4263B GPIB Interface GPIB Interface is used for remote control of the 4263B using the General Purpose Interface Bus (GPIB). GPIB is a standard for interfacing instruments to computers, and supports for IEEE 488.1, IEEE 788.2, IEC-625, and JIS-C1901. GPIB allows instruments to be controlled by an external computer which sends commands or instructions to and receives data from the instrument.

4263B Technical Information This section discuss the 4263B's theory of operation and the technical information. Overall Impedance Measurement Theory The 4263B measures the impedance of the Device Under Test (dut ) in the following manner: Figure 3-6. Simpli ed Model of Impedance Measurement Figure 3-6 shows the simpli ed model of the 4263B impedance measurement. Vs is the test signal level (voltage) and Rs is the source resistance.
PAGE 94
4263B In Figure 3-7, R: X: jZj : Resistance Reactance : Absolute value of impedance Phase of impedance The 4263B denotes the absolute value jZj of impedance with Z. Note Impedance, Z, can also be expressed as admittance, Y. Admittance is expressed in terms of impedance, Z, as follows: 1 Y = Z Figure 3-8. Relationship Between Impedance and Admittance For parallel connected circuits, it is better to use admittance, Y. Figure 3-9.
PAGE 95
4263B The 4263B denotes the absolute value jYj of admittance with Y. Note The 4263B measures a DUT's impedance, Z, which is a vector value, and gives the result using the following equivalent circuits: Figure 3-10.
PAGE 96
4263B Transformer Parameters Measurement Note This function only applies to the 4263B with option 001. DCR measurement | Ls-Rdc, Lp-Rdc Where, Ls : Lp : Equivalent series inductance Equivalent parallel inductance Rdc : DC resistance The 4263B has an internal DC voltage source for DCR measurement. The DC voltage level is 2 V. The 4263B switches test signal source to DC for DC Resistance measurement, and to AC for LS or LP measurement.
PAGE 97
4263B Warning While H terminal of the 4263B is connected to a terminal of the transformer, high-voltage can be induced at the other terminals. For safe operation, when connecting or disconnecting a transformer, connect the transformer leads in the following order: Connect transformer, rst to L , L , and H terminals, and then connect the H terminal last. Disconnect the transformer from the H terminal rst, and then the H , L , and L terminals.
PAGE 98
4263B Test Current Level Figure 3-6 shows the 4263B's simpli ed model. The actual current level applied to a DUT depends on the test signal level (Vs), the DUT's impedance value (Z), and the 4263B's source resistance (Rs) which is in series with the DUT. The actual current level (I) through the DUT is calculated using the following equations. There are two di erent equations according to which voltage source is used: AC or DC.
PAGE 99
4263B When measuring DCR or R2, the actual test current level through the DUT can be obtained as follows: The source resistance, Rs, is selected by measured the DUT's resistance value, RDUT .

4 Remote Operation (To Control from a Computer) This chapter provides step-by-step instructions for controlling the 4263B using GPIB remote mode. The examples in this manual use the HP 9000 series 200 or 300 BASIC language. This chapter covers the following: Getting started Setting up the 4263B Triggering a measurement Retrieving measurement data Other features If you have a problem Refer to Chapter 5 for the description of each GPIB command.
PAGE 102
4263B Getting Started This section will teach you the basics of operating the 4263B in GPIB remote mode (from now on referred to as remote). This includes reading the GPIB address, sending commands to the 4263B, and retrieving data from the 4263B. Input/Output Statements The statements used to operate the 4263B in remote depend on the computer and the programming language being used. In particular, you need to know the statements the language uses to input and output information.
PAGE 103
4263B Returning to Local Mode When you press a key on the 4263B's keyboard while operating in remote, the 4263B does not respond. This is because in remote (as indicated by the display's Rmt annunciator) the 4263B ignores all front panel inputs except the key. To return the 4263B to the Local mode, press the . Query Commands There are several commands in the alphabetic command directory that end with a question mark.
PAGE 104
4263B Remote Operation Most measurements can be modeled by the following simple three step sequence: 1. Set up the instrument. Typically, you begin the setup step by sending *RST to set the instrument to its default settings. Next, if you need values di erent from the default settings, change the settings one by one as required. 2. Trigger the measurement. The trigger may be generated automatically by steps taken in your setup commands, or you can send an explicit trigger command.

4263B Reading Out Measured Result This section describes how to read out the measured result. You can read out the measured result in two ways: reading out data for each measurement or reading out data of several measurements in batch. The three commands shown in the table below can be used to read out the measured data for each measurement.
PAGE 117
4263B Reading out measured result using *TRG command This command actually performs two tasks: it triggers the instrument and returns the results. It is useful, for example, when you want to retrieve measurement results immediately after triggering the instrument from an external controller. The readout procedure using the *TRG command is described below. 1. Use the :TRIG:SOUR command to set up the trigger mode to the GPIB trigger (Bus). 2. Execute the *TRG command. 3.

4263B Concept of Subsystem Command Tree The top of the subsystem command tree is called the root command , or simply the root . To reach the low-level commands, you must specify a particular path (like DOS le directory path). After Power ON or after *RST, the current path is set to the root. The path settings are changed as follows: Message Terminator A message terminator, such as < new line> character, sets the current path to the root.

7 Impedance Measurement Basics This chapter contains more detailed information on measurements using the 4263B, that should help you to work more e ciently. The following sections are included.
PAGE 190
4263B Characteristics Example Figure 7-1 shows typical characteristics of various components. As can be seen in the gure, a component can have di erent e ective parameter values dependent upon its operating conditions. The measured values most useful in actual applications are obtained from precise measurement under the actual operating conditions. Figure 7-1.
PAGE 191
4263B Parallel/Series Circuit Mode There are two equivalent circuit models used to measure L, C, or R components. They are the parallel and series models as shown in Table 7-1. Circuit Model Cp Model Cs Model Lp Model Ls Model Table 7-1.
PAGE 192
4263B Selecting Circuit Model for Capacitance Measurement The following description gives some practical guide lines for selecting the appropriate capacitance measurement circuit model. Small Capacitance Values Small capacitance yields a large reactance, which implies that the e ect of the large value parallel resistance (Rp) has relatively more signi cance than that of the low value series resistance (Rs). So the parallel circuit model (Cp-D, Cp-Q, or Cp-G) is the one to use. (Refer to Figure 7-2 (a).
PAGE 193
4263B Selecting Circuit Model for Inductance Measurement The following description gives some practical guide lines for selecting the appropriate inductance measurement circuit model. Small Inductance Values For low values of inductance the reactance is typically small so Rs is more signi cant. Therefore , the series circuit model (Ls-D, Ls-Q, or Ls-Rs) is appropriate. (Refer to Figure 7-3 (a).
PAGE 194
4263B Four-Terminal Pair Con guration The 4263B uses the four-terminal pair measurement con guration which permits easy, stable, and accurate measurements and avoids the measurement limitations due to factors such as mutual inductance, interference of the measurement signals, and unwanted residual in the test connections. Figure 7-4 shows the four-terminal pair measurement principle. The UNKNOWN terminals consists of four coaxial connectors.
PAGE 195
4263B Measurement Contacts To realize accurate measurements using the four-terminal pair measurement technique, the following two conditions are required: (Refer to Figure 7-5 for each numbered point.) 1. The signal path between the LCR Meter and DUT should be as short as possible. 2. For a four-terminal pair measurement circuit con guration, the outer shields of HCUR and HPOT, LCUR , and LPOT terminals must all be connected together at a point as near as possible to the DUT. Figure 7-5.
PAGE 196
4263B Capacitance to Ground To measure capacitors of 10 pF or less, the stray capacitance between the measurement contacts and the conductors near the capacitor will in uence the measurement, as shown in Figure 7-6. Figure 7-6. Model of Capacitance to Ground To minimize the stray capacitance of the test leads, the center conductor of the test leads should be kept as short as possible, as shown in Figure 7-7, (A).
PAGE 197
4263B Contact Resistance Contact resistance between the contacting terminals and the DUT causes measurement error when measuring large values of capacitance, especially in D (dissipation factor) measurements. When measuring large capacitance values, the four-terminal measurement contacts have the advantage of less measurement error as compared to the two terminal method. Select a test xture which can hold the DUT tight to stabilize the connection and to give the lowest contact resistance. Figure 7-8.
PAGE 198
4263B Using a Guard Plate for Low Capacitance Measurements Use a guard plate to minimize measurement errors caused by stray capacitance when measuring low capacitance values, such as chip capacitors. See Figure 7-10. Figure 7-10. Example of DUT Guard Plate Connection Shielding Shielding minimizes the e ects of electrical noise picked up by the test leads. So, provide a shield plate and connect it to the outer shield conductors of the four-terminal pair test leads as shown in Figure 7-11. Figure 7-11.
PAGE 199
4263B Contact Check To realize accurate measurements and to make the contact check function work correctly, use the following guide lines. Using the four-terminal pair con guration, place your test leads as near as possible to the DUT. Minimize CHL and CPC by arranging your test leads as shown in Figure 7-12. If CHL is large, the valid range of the contact check is reduced. If CPC is larger than about 3 pF, the contact check function may perceive that the DUT is connected even if it is not. Figure 7-12.
PAGE 200
4263B Correction Functions of the 4263B The 4263B has the following correction functions, Cable Length correction, OPEN, SHORT, and LOAD corrections. These correction functions are used to correct errors due to test xtures and test leads. Table 7-2 lists these correction functions with a brief description of each. Correction Selection Cable Length Correction OPEN/SHORT Correction OPEN/SHORT/LOAD Correction Table 7-2. Correction Functions Description Correct phase shift error due to the test leads.

4263B Measurements using Agilent test leads and a test xture. In this case, the Cable Length correction and the OPEN/SHORT correction are used. Measurement using a xture that has complicated residual errors. Perform the OPEN/SHORT/LOAD correction using a LOAD standard.
PAGE 202
4263B Standard for the LOAD Correction You need a standard to do the LOAD correction. This can be any standard which has speci ed reference values. The type of standard does not have to be same as the device to be measured. That is, a capacitor standard can be used when you want to measure inductors. Using a Standard Supplied by a Component Manufacturer Use the manufacturer speci ed values of the standard as the reference values for the LOAD correction.

B Handler Interface Installation Introduction This appendix describes the electrical characteristics of each signal line of the handler interface. Electrical Characteristics Output Signals Each DC output is isolated using open collector output opto-isolators. The output voltage of each line is enabled by putting pull-up resistors on the main board, and by connecting the pull-up resistors to an externally applied DC voltage.

PAGE 280
4263B Input Signals The DC isolated input signals are connected to the cathodes of the LEDs in the opto-isolators. The anodes of the LEDs are powered by an external voltage source (EXT DCV2). The OFF state voltage (high level) of the DC isolated input signals depends on the pull-up voltage powered by an external voltage source (EXT DCV2). (The input current is restricted by using a switch on the main board.) The electrical characteristics of the input signals are listed in Table B-2.
PAGE 281
4263B Handler Interface Board Setup Before using the handler interface, connect the pull-up resisters to enable the output signals and set the dip switch to select the voltage level for the input signals. Caution SUSCEPTIBLE TO DAMAGE FROM ESD. Perform the following procedures only at a static-safe workstation and wear a grounding strap. Tools and Fasteners The 4263B mechanical components are secured using metric threaded fasteners.
