2. Overview of Remote Control 2 Overview of Remote Control This chapter gives an overview of the GPIB remote control system and GPIB commands.
Overview of Remote Control Setting Up a GPIB Remote Control System Setting Up a GPIB Remote Control System This section describes how to set up a GPIB remote control system. What is GPIB? GPIB (General Purpose Interface Bus) is an interface standard for connecting a computer with peripherals. It complies with these international standards: IEEE 488.1, IEC-625, IEEE 488.2, and JIS-C1901.
Overview of Remote Control Setting Up a GPIB Remote Control System Possible sizes and configurations of your remote control system One GPIB system can host up to 15 devices. • Device-to-device cables should be no longer than 4 m. The total length of connection cables used in one GPIB system should not exceed 2 m ´ N, where N is the number of connected devices (including controller). In any case, do not construct a system whose total cable length exceeds 20 m.
Overview of Remote Control Sending GPIB Command Messages Sending GPIB Command Messages Types and structure of GPIB commands GPIB commands available with the 4287A can be divided into two groups: 4287A specific commands These commands are specific to the 4287A. They provide access to all measurement features and some generic features built into the 4287A. Commands in this group have a hierarchical (multi-level) structure called the “command tree” (see Appendix D, “GPIB Command Tree”).
Overview of Remote Control Sending GPIB Command Messages Figure 2-2 Using colons and semicolons 2. Overview of Remote Control Message syntax This section describes the syntax for sending program messages via GPIB. Program messages are sent by the user from an external controller to the instrument to control the instrument. A program message contains one or more commands along with any required parameters. Case sensitivity Program messages are not case sensitive.
Overview of Remote Control Sending GPIB Command Messages Remote mode The 4287A does not have a remote mode. Therefore, the 4287A is not automatically set to the remote mode when it receives a GPIB command. Furthermore, there is no local key to clear the remote mode on the 4287A’s front panel. Use the key lock function to prevent mis-input from the front panel keys. To lock the front panel, the keyboard or the mouse, use the following commands.
3. Specifiying Measurement Conditions 3 Specifying Measurement Conditions This chapter explains how to set measurement conditions and configure the instrument’s display of measurement results.
Specifying Measurement Conditions Setting Measurement Parameters Setting Measurement Parameters You can assign measurement parameters 1 through 4 (:PAR1, :PAR2, :PAR3, and :PAR4) independently of the other parameter settings.
Specifying Measurement Conditions Setting Measurement Point Setup Tables (Signal Source and Averaging Factor) Setting Measurement Point Setup Tables (Signal Source and Averaging Factor) You can use up to eight measurement point setup tables (Tables 1 through 8) to define the signal source frequency and averaging factor for each measurement point. Each measurement point setup table can contain up to 32 measurement points. When you set measurement points, new settings are applied to the active table.
Specifying Measurement Conditions Choosing Whether to Measure the DUT at a Single Point or Multiple Points Choosing Whether to Measure the DUT at a Single Point or Multiple Points Before starting a measurement session with the 4287A, you need to choose whether to measure the DUT at all points defined in the table or at a single point, that is, list measurement versus single-point measurement.
Specifying Measurement Conditions Setting How the Instrument Displays Measurement Results (Enabling/Disabling Deviation Measurement Mode) Setting How the Instrument Displays Measurement Results (Enabling/Disabling Deviation Measurement Mode) You can have the instrument display measurement results as absolute values or as deviations relative to the reference value (deviation measurement mode). You can change this setting for each of the measurement parameters 1 through 4 (:PAR1 through :PAR4).
Specifying Measurement Conditions Configuring Screen Display Configuring Screen Display Configuring the display of measurement results Showing/hiding all measurement results You can instruct the instrument to show or hide the entire set of measurement results, which includes the measurement results for measurement parameters 1 through 4, test signal level monitoring, and Rdc measurement).

4. Preparing for Accurate Measurement 4 Preparing for Accurate Measurement This chapter explains how to carry out calibration, compensation, and test fixture selection (port extension compensation).
Preparing for Accurate Measurement Performing Calibration Performing Calibration Setting calibration kit values You can select either the 4287A option 700 (16195B 7-mm calibration kit) or a user-defined calibration kit. To make this selection, use the following command: :CORR1:CKIT on page 231 • If you opt to use a user-defined calibration kit, you need to specify how you define the calibration kit and then enter the definitions.
Preparing for Accurate Measurement Performing Calibration After obtaining the data for calculating the calibration coefficients for all of the OPEN, SHORT, and LOAD standards (including the data for both impedance and Rdc measurements), issue the following command to calculate the calibration coefficients and turn on the calibration function: • NOTE :CORR1:COLL:SAVE on page 246 You cannot directly turn on or off the calibration function.
Preparing for Accurate Measurement Performing Calibration Step 4. To measure a low-loss capacitor, connect the low-loss capacitor and then issue the :CORR1:COLL or :CORR1:COLL:RF command, which designates “STAN4” as the parameter. Step 5. Connect the OPEN standard for Rdc measurement and then issue the :CORR1:COLL:DC command, which designates “STAN1” as the parameter. Step 6. Connect the SHORT standard for Rdc measurement and then issue the :CORR1:COLL:DC command, which designates “STAN2” as the parameter.
Preparing for Accurate Measurement Performing Calibration LOAD standard: 25 to 100 W OPEN standard: 100 W or higher NOTE When you validate the Rdc measurement results returned by the :DATA:RCAD{1-3}? command, you should use the absolute value for the following reasons. When you measure the SHORT standard, whose resistance is extremely low (nearly zero) and susceptible to disturbance during measurement, the command may return a small negative Rdc value.
Preparing for Accurate Measurement Performing Calibration Sample program Example 4-1 shows a sample program that demonstrates how to obtain the measurement data for calculating the calibration coefficients. You can find the source file of this program, named calib.bas, on the sample program disk. The sample program begins by configuring the measurement point setup table and calibration kit.

Preparing for Accurate Measurement Selecting a Test Fixture (Port Extension Compensation) Selecting a Test Fixture (Port Extension Compensation) Using port extension compensation function To compensate for the delay due to the test fixture that holds the DUT (port extension compensation), you must tell the instrument which test fixture is used in your measurement. This can be done by selecting data for electrical length compensation, which is predefined and specific to each test fixture.
Preparing for Accurate Measurement Running the Compensation Process Running the Compensation Process NOTE You must turn on the calibration function before using it. In other words, when the calibration function is off, you cannot perform any of the compensation related operations, including measuring the data for calculating the compensation coefficients, calculating the compensation coefficients, turning on or off the compensation function, and retrieving or setting the compensation coefficients.
Preparing for Accurate Measurement Running the Compensation Process source is not Internal trigger, you must trigger the instrument after issuing the command. To define the OPEN and SHORT compensation standards using the commands described so far, follow these steps: If you use the same standards for both impedance and Rdc measurements or you omit Rdc measurement: Step 1. Connect the OPEN standard and then issue the :CORR2:COLL command, which designates “STAN1” as the parameter.
Preparing for Accurate Measurement Running the Compensation Process Calculating compensation coefficients and turning on/off compensation function After measuring the data for calculating the compensation coefficients, issue the following commands to calculate the compensation coefficients and turn on the compensation function: Measured data OPEN and SHORT OPEN only GPIB command Status of compensation function after calculation OPEN SHORT :CORR2:COLL:SAVE on page 255 On On :CORR2:COLL:OPEN on pag
Preparing for Accurate Measurement Running the Compensation Process The measurement data of the OPEN and SHORT standards used for calculating the compensation coefficients for impedance measurement are stored in the calibration data array (see “Compensation Data Arrays” on page 81). You can retrieve this data with the following command: • :DATA:CMD{1-2}? on page 261 This command returns RF measurement data without compensation, which require more complex handling than Rdc values.
Preparing for Accurate Measurement Running the Compensation Process Sample program Example 4-2 shows a sample program that demonstrates how to obtain the measurement data for calculating the compensation coefficients. You can find the source file of this program, named compen.bas, on the sample program disk. The sample program begins by configuring the measurement point setup table, retrieving the calibration coefficients determined in Example 4-1 from the file, and configuring the instrument accordingly.

5 Starting Measurement Cycle (Triggering) and Detecting End of Measurement 65 5. Starting Measurement Cycle (Triggering) and Detecting End of Measurement This chapter explains how to trigger the instrument to start a new measurement cycle and how to detect the end of a measurement cycle.
Starting Measurement Cycle (Triggering) and Detecting End of Measurement Starting a New Measurement Cycle (Triggering) Starting a New Measurement Cycle (Triggering) Trigger system The trigger system is responsible for such tasks as detecting the start of a measurement cycle (triggering) and controlling the pre-measurement delay time. As shown in Figure 5-1, the trigger system has three states: Idle, Waiting for Trigger, and Measurement.
Starting Measurement Cycle (Triggering) and Detecting End of Measurement Starting a New Measurement Cycle (Triggering) Waiting for Trigger state (Trigger Event Detect state) The trigger system is put into Measurement state (arrow b in Figure 5-1) after the elapse of the trigger delay time (set with the :TRIG:DEL command on page 308) if the instrument is triggered (a trigger is detected) or the :TRIG command on page 308 is issued while the trigger system is in Waiting for Trigger state.
Starting Measurement Cycle (Triggering) and Detecting End of Measurement Starting a New Measurement Cycle (Triggering) Measurement state (sequence operation state) In Measurement state, the trigger system waits until the measurement point delay time (set with the :TRIG:SEQ2:DEL command on page 309) elapses and then starts measurement for each measurement point.
Starting Measurement Cycle (Triggering) and Detecting End of Measurement Starting a New Measurement Cycle (Triggering) Starting a measurement cycle (Triggering the instrument) Configuring the instrument to automatically perform continuous measurement (initial setting): Step 1. Issue the :TRIG:SOUR command on page 310 to set the trigger source to Internal trigger. Step 2.
Starting Measurement Cycle (Triggering) and Detecting End of Measurement Waiting for (Detecting) End of Measurement Waiting for (Detecting) End of Measurement The status of the 4287A can be detected through the status registers. This section describes how to detect the end of measurement by using the status registers. For a complete description of the status report mechanism, including the specifications of each bit, see Appendix B, “Status Reporting System.
Starting Measurement Cycle (Triggering) and Detecting End of Measurement Waiting for (Detecting) End of Measurement Sample program Example 5-1 is a sample program using an SRQ to detect the end of measurement. This program is given the file name srq_meas.bas and stored on the sample program disk. This program aborts the trigger system, makes the SRQ setting, and then initiates the trigger system one time.

6. Retrieving Measurement Results 6 Retrieving Measurement Results This chapter explains how to retrieve the results of impedance measurement, test signal level monitoring, and Rdc measurement. It also describes how the Agilent 4287A internally processes the data.
Retrieving Measurement Results Data Transfer Format Data Transfer Format When you transfer data with the following commands, you can select either the ASCII format or binary format. NOTE When you transfer data with commands other than the following, you cannot select the data transfer format because it is fixed as the ASCII format.
ASCII format When you select the ASCII format as the data transfer format, numbers are transferred as ASCII bytes, each of which corresponds to one of the formats shown below. Note that numbers are separated by a comma (,) in accordance with the IEEE 488.2 specification. NOTE Since numeric data strings vary in length, commas appear at varying points in the data. Keep this in mind as you extract data from retrieved numeric data strings in your program.

Figure 6-3 Binary Format In this format, the data is represented with a hash (#) mark, the number 6 (indicating that is 6 bytes), the number of the binary data to be transferred (), the binary data itself, and finally the message terminator ^END.
Internal Data Processing Data flow Figure 6-5 gives an overview of the 4287A's internal data processing flow. Figure 6-5 4287A's data processing flow Chapter 6 77 6.
Retrieving Measurement Results Internal Data Processing Internal data arrays The instrument has a number of internal data arrays/sets that can be read and/or written and contain either real or complex numbers (Table 6-1).
Data Array The Data Array contains complex numbers (R-X) that indicate the results of calibrating raw measurement data. To retrieve the Data Array, use the following command: • :DATA:RAW? on page 264 Display Data Arrays As shown in the table below, the instrument has four Display Data Arrays corresponding to parameters 1 through 4.
Retrieving Measurement Results Internal Data Processing Calibration Data Arrays As shown in the table below, the instrument has eight Calibration Data Arrays corresponding to two measurement passes for each of the OPEN, SHORT, LOAD, and LOW LOSS CAPACITOR standards. Each Calibration Data Array contains the standard measurement data (complex numbers) necessary for calculating the calibration coefficients.
NOTE When setting calibration coefficients, note the following: • To ensure that the instrument will provide correct measurement results, you must first configure the instrument to use the same measurement points (point setup table settings) as when you obtained measurement data for calibration and then set all the coefficients. • You must turn on the calibration functions before setting the calibration coefficients.
Retrieving Measurement Results Internal Data Processing Current/Voltage Monitor Arrays The Current/Voltage Monitor Arrays contain the real numbers to be displayed as the monitored values of the test signal voltage and current levels. Each value contained in these arrays is calculated based on the test signal level setting and the impedance value determined by performing port extension and compensation on the Data Array.
Rdc Display Data The Rdc Display Data is the data obtained by performing Rdc-specific calibration and compensation on the results of Rdc measurement. To retrieve this data, use the following command: • :DATA:RDC? on page 267 Calibration coefficients and calibration data for Rdc measurement When the instrument performs Rdc measurement (DC measurement), it uses a specific set of calibration coefficients (real numbers) that are different from those used for impedance measurement.
Retrieving Measurement Results Internal Data Processing Rdc compensation coefficients and compensation data When the instrument performs Rdc measurement (DC measurement), it uses a specific set of compensation coefficients (real numbers) that are different from those used for impedance measurement. This means that the standard measurement data (real numbers) necessary for calculating the compensation coefficients is measured and retained separately from those for impedance measurement.

Sample Application Programs Measuring Array (Multi-Element) Components Measuring Array (Multi-Element) Components When measuring an array component with the scanner, you must select appropriate calibration coefficients for each channel, switched by the scanner, to make a correct measurement (by eliminating errors that depend on measurement paths). The 4287A can handle up to 8 tables for different measurement conditions (including calibration coefficients).
Sample Application Programs Measuring Array (Multi-Element) Components Step 3. Performing measurement After setting the channels, perform measurement for each channel while changing the active table to the corresponding table with the :READ? command on page 293. During measurement, use the /READY_FOR_TRIG signal for appropriate trigger timing. For details on the timing of trigger input, refer to “Trigger Input Timing When Using the :READ? Command” on page 98.

B. Status Reporting System B Status Reporting System This appendix describes the status reporting system of the Agilent 4287A.
Status Reporting System General Status Register Model General Status Register Model The Agilent 4287A has a status reporting system to report the condition of the instrument. Figure B-1 General Status Register Model The status reporting system has a hierarchical structure as shown in Figure B-1.When the instrument satisfies a particular condition, the corresponding bit of the event register is set to 1.Therefore, you can check the instrument status by reading the event register.
Status Reporting System General Status Register Model Event register The event register reflects the corresponding condition of the 4287A (e.g., occurrence of an event) as a bit status. These bits continuously monitor changes in the 4287A’s state and change the bit status when the condition (e.g., change bit status to “1” if a specific event occurs) for each bit is met. You cannot change the bit status by issuing a GPIB command.
Status Reporting System General Status Register Model Condition register and transition filter When the status register has a transition filter, there is a lower register called a condition register under the event register. The transition filter is between the event register and the condition register. The transition filter enables you to select a positive and/or negative transition of the condition register bit in order to set a bit in the corresponding event register.
Status Reporting System Status Register Structure Status Register Structure The status reporting system has a hierarchical structure as shown in Figure B-3. The status byte register is a summary of registers in the lower level. This section describes status registers in each hierarchy. Each bit of the status register is described in Table B-1 through Table B-4. Figure B-3 Status Register Structure B.
Status Reporting System Status Register Structure Table B-1 Status Bit Definitions of Status Byte (STB) Bit Position 0, 1 Name Description Not used Always 0 Error/Event Queue Set to “1” if the error/event queue contains data; reset to “0” when all of the data has been retrieved. 3 Questionable Status Register Summary Set to “1” when one of the enabled bits in the status event status register is set to “1.

1. Chapter Title 2. Chapter Title 3. Chapter Title H. Error Messages H Error messages 365 5. Chapter Title The Agilent 4287A provides error messages to indicate its operating status. This appendix describes the error messages of the 4287A in order of error number. To search error messages alphabetically, refer to the Operation Manual.
Error messages Error number: No number Error messages are displayed at the top of the 4287A’s LCD. Error messages generated during the execution of a GPIB command are preceded by the string “[GPIB]” or “[TELNET]” and can be read out using the GPIB command. This section describes each error message and its remedy. You can clear error messages displayed on the screen using the following commands.
0 (No error) No error has occurred. 1. Chapter Title Error messages Error number: 0 This message is not displayed on the LCD. 0 is returned as the error number if no error has occurred in the instrument when the :SYST:ERR? command on page 304 is sent through GPIB. 6 Additional standards needed Measure all of the required data. 7 2.
Error messages Error number: 104 104 Save error When saving a file, anomalies in the storage media are detected. For example, when you attempt to save a file on a floppy disk, there is not enough space on the disk. Make sure there is enough space on the floppy disk. 105 Recall error An error occurs while reading out (recalling) a file. For example, you attempt to read out a file with invalid contents (such as an instrument setting file with extension “.
-100 Command error A comprehensive syntax error occurs for which the 4287A cannot detect further details of the error. This error code simply indicates the occurrence of a command error that is defined in IEEE488.2,11.5.1.1.4. -101 Invalid character Syntax error There is a command or data type that cannot be recognized. For example, in a correct program message “:SYST:PRES”, a colon (:) is inserted by mistake to give “:SYST::PRES”. -103 2.
Error messages Error number: -121 -121 Invalid character in number An invalid character for the data type of the syntax analysis target is received. For example, alphabetical characters exist in a decimal value or “9” exists in octal data. -123 Exponent too large The absolute value of the exponent exceeds 32,000. (Refer to IEEE488.2,7.7.2.4.1.) -124 Too many digits The number of digits of the mantissa of the decimal value data element exceeds 255 except for preceding 0s. (Refer to IEEE488.27.7.2.4.1.
-170 Expression error An error not included in error numbers between -171 and -179 occurs during the syntax analysis of equation data. -171 1. Chapter Title Error messages Error number: -170 Invalid expression The equation data element is invalid. (Refer to IEEE488.2,7.7.7.2.) For example, parentheses are not paired or a character violates the standard.
Error messages Error number: -310 -310 System error One of the “system errors” defined for the 4287A occurs. -321 Out of memory An internal operation needed more memory than is available. -400 Query error A comprehensive Query error occurs for which the 4287A cannot detect further details. This code simply indicates the occurrence of a Query error that is defined in IEEE488.2,11.5.1.1.7 and 6.3. -410 Query INTERRPUTED This indicates the status that causes an “INTERRUPTED” Query error.
