1 Command Guidelines Rules and guidelines for using General Purpose Interface Bus (GPIB) programming are contained in this chapter. Chapters 3 and onwards outline each GPIB command subsystem used with the Agilent 8922M/S. Each subsystem chapter starts with a syntax diagram followed by a simple explanation of each command within that subsystem.
Command Guidelines Command Names Command Names Generally all commands of greater than four characters have an alternate abbreviated form using only the upper case letters and number (if used). Upper or lower case characters may be used for all commands.
Command Guidelines If you have Agilent Technologies 8922M/S Option 010 Quotation marks “ ”, enclose command and string entries. Be sure to follow the correct syntax for using quotations that are specific to your basic language. Colons :, are used to separate keywords and show hierarchical relationship. ”RFANalyzer:FREQuency 935 MHz” A Semicolon and a Colon ;:, are used to separate two or more root level command statements on the same line.
Command Guidelines Units of Measure Units of Measure Units for measurements These are implemented such that a measurement query result will be returned in the current GPIB unit. Units for settings These are implemented such that if a unit is not sent along with the setting value, then a default GPIB unit is used. • For example, RFGenerator:AMPLitude1 assumes dBm and RFGenerator:FREQuency assumes Hz. If a unit is sent with the setting, then this unit will be used.
Command Guidelines Measurement Subsystems Measurement Subsystems Measure Subsystem Commands Measure commands are used to control measurements and get back the value of the displayed measurement. To get a valid measurement, the instrument must first be set up to access the desired measurement. In most cases, this means that you must be on the screen (or set of screens) associated with the measurement.
Command Guidelines Optional Commands Optional Commands The following lists the optional command groups that are used with many of the GPIB Command Subsystems. The list describes the abbreviation used for each optional set and its corresponding Appendix, that gives more details of the options available.
Command Guidelines Command Descriptions Command Descriptions Each command in this guide is given a description, an example of its syntax and possible options. These commands are shown as follows; Command Name Description This gives a brief description of what the command can be used for. Some units that can be used with the command, are also listed. Syntax This gives the syntax for the command.
Command Guidelines Output RF Spectrum Modulation Reference Measurement Averaging Output RF Spectrum Modulation Reference Measurement Averaging The Agilent 8922M/S makes the modulation reference measurement of the Output RF Spectrum (ORFS) due to modulation test based on a single burst measurement. If you wish to comply with the GSM Recommendation 11.10, then the following information will be of interest.
2 GPIB Tutorial and Examples This Chapter introduces the user to automatic GSM mobile phone testing using the Agilent 8922M and Agilent 8922S GSM Test Set. GPIB (IEEE 488.2) is used in conjunction with BASIC programming exercises and example programs to illustrate the most effective techniques for efficient and high speed phone tests.
GPIB Tutorial and Examples GPIB Programming Exercises GPIB Programming Exercises Before Starting Power-up the Agilent 8922M/S and carry out the following checks before beginning the exercise: ❒ On the rear panel, the OPT 001 REF OUT should be connected with a short BNC cable to the REF IN connector. ❒ Use the front panel knob to select the CONFIG screen. Check the Compatible field is set to 8922M or 8922S. ❒ On the CONFIG screen, set the GPIB address to 14 and check the GPIB mode is set to talk&lstn.
GPIB Tutorial and Examples Exercise A - Establishing a Link Exercise A - Establishing a Link Originate a Call Begin the program by setting the GPIB address variable Uut=714, then select commands from section “GPIB Commands Used in Exercises” to carry out the following actions: ❒ Preset the Agilent 8922M/S and set up the paging IMSI and external cable loss, zero the power meter. ❒ Page the mobile. ❒ Establish a program loop to wait for the mobile to answer the call.
GPIB Tutorial and Examples Example B - Controlling the Mobile Example B - Controlling the Mobile Mobiles need to be tested on a variety of frequency channels (ARFCN) and transmitter power levels (TX Level). The Agilent 8922M/S uses over-the-air signalling to command the mobile to any ARFCN or TX Level. ARFCN changes can be made using channel assignments, with the signalling taking place over the GSM Fast Associated Control Channel (FACCH).
GPIB Tutorial and Examples Example B - Controlling the Mobile Tips: The BASIC FOR NEXT loop is ideal for controlling the TX Levels. For example, start the loop with FOR Txlevel = 5 TO 15 and end with NEXT Txlevel. Use a REPEAT UNTIL structure to check the reported TX Level. This time, use a delay of WAIT 0.4. For more help, look at the ‘PERFORM FAST POWER MEASUREMENTS’ section of example program 1 in section “Example Programs”.
GPIB Tutorial and Examples Example C - Making Measurements Example C - Making Measurements In this section we first add a TX Power measurement, then modulation accuracy and receiver sensitivity tests. TX Power Measurement TX peak power is measured using the Fast TX Carrier Power measurement. This measurement can take place in parallel with GSM signalling operations such as ARFCN or TX Level changes. TX peak power is normally displayed on the Cell Control screen.
GPIB Tutorial and Examples Example C - Making Measurements Tips: For help, look at the “PERFORM FAST POWER MEASUREMENT” section of example program 1. DSP Measurements Modulation accuracy for GSM is determined by measuring the phase and frequency error. The Agilent 8922M/S uses its DSP analyser for making this measurement. When triggered, the DSP analyser samples a single GSM TDMA burst and performs several measurements in parallel namely: peak phase error, rms.
GPIB Tutorial and Examples Example C - Making Measurements Select commands from section “GPIB Commands Used in Exercises” to create the following program flow: ❒ Select single trigger mode for DSP measurements. ❒ Establish call as in exercise A. ❒ Perform TX peak power test on channels 1, 63, 124, levels 5 to 15 with code from exercise B and C. ❒ Display the DSP analyser phase and frequency error screen. ❒ Set up a loop to count through three TX Levels: 5, 10 and 15.
GPIB Tutorial and Examples Example C - Making Measurements Receiver Sensitivity Test Bit Error Ratio (BER) is the primary measure of GSM receiver sensitivity. For a handheld mobile, the residual type II BER should be less than 2.4% at -102dBm. For most mobile testing, the downlink power will be maintained at a relatively high level of around -80dBm. This level is dropped to -102dBm to perform the BER test, then increased again to -80dBm once the test is complete.
GPIB Tutorial and Examples Example C - Making Measurements Tips: Experiment with shorter AGC settling times, notice the reported BER increase. Try increasing the RF Generator power to -40dBm at the start of the program and removing the wait statement. Does the phone drop the call? The required delay depends on the mobile and the size of the level change. Look at the mobile’s SACCH reports of RXQual and RXLev. Consider modifying your program to use these reports to decide when the mobile’s AGC has settled.
GPIB Tutorial and Examples Example D - Adding Robustness Example D - Adding Robustness There are several additions which can be made to your program to increase its robustness: ❒ Check input power falls within +/-3dB specified analyser range ❒ Check DSP measurement status ❒ Check for Agilent 8922M/S error logs ❒ Provide a time-out for any measurements which do not complete These checks add little value to a program designed to test phones which are known to meet specification.
GPIB Tutorial and Examples Example E - Faster Testing Example E - Faster Testing Load and run example program 1, then program 2, then program 3, or look at the test times tabulated in section 4 for the Agilent 8922M. The three programs are configured to perform an identical list of tests, yet their test times are different. This is achieved using various techniques. Example program 1 does use some techniques to improve speed: ❒ The complete set of DSP measurements are performed in parallel.
GPIB Tutorial and Examples Example E - Faster Testing Example program 3 uses the Agilent 8922M/S Aux RF Out port to simulate a mobile operating in a test mode. Mobiles controlled in test modes react much faster to channel and TX Level change commands. ❒ Delays associated with the GSM SACCH and FACCH are removed. ❒ Measurements are made with no signalling overhead time. The time savings made in programs 2 and 3 have been almost completely during the TX part of the test.

IEEE 488.2 Common Commands *CLS (Clear Status) *CLS (Clear Status) Description The *CLS (clear status) common command clears the status data structures, including the device defined error queue. This command also aborts the *OPC. If the *CLS command immediately follows a PROGRAM MESSAGE TERMINATOR, the output and the MAV (message available) bit will be cleared.
IEEE 488.2 Common Commands *ESE (Event Status Enable) *ESE (Event Status Enable) Description The *ESE command sets the Standard Event Status Enable Register bits. The Standard Event Status Enable Register contains a mask value for the bits to be enabled in the Standard Event Status Register. A “one” in the Standard Event Status Enable Register will enable the corresponding bit in the Standard Event Status Register, a logic zero will disable the bit.
IEEE 488.2 Common Commands *ESR? (Event Status Register) *ESR? (Event Status Register) Description NOTE The *ESR? query returns the contents of the Standard Event Status Register. Reading the Standard Event Status Register clears the contents of the register.
IEEE 488.2 Common Commands *IDN? (Identification Number) *IDN? (Identification Number) Description The *IDN? query allows the instrument to identify itself. It returns the string: ”Hewlett-Packard,8922M,0,X.UU.VV” X.UU.VV = the firmware revision of this instrument. An *IDN? query must be the last query in a message. Any queries after the *IDN? query in this program message will be ignored. Query Syntax *IDN? Returned Format Hewlett-Packard,8922M,0,X.UU.
IEEE 488.2 Common Commands *OPC (Operation Complete) *OPC (Operation Complete) Description The *OPC (operation complete) command will cause the instrument to set the operation complete bit in the Standard Event Status Register only when all pending operations are complete. The *OPC? query places an ASCII “1” in the output queue when all pending device operations are complete. There is a one second minimum delay between the query and the response.
IEEE 488.2 Common Commands *OPT? *OPT? Description The *OPT? query will return a string containing the instrument options that are installed. Returns a “0” for any options that are not installed. Available options are “SPECTRUM ANALYZER”, “LOW POWER RF ATTEN”,“CIPHERING”, “HP83220A”, ”HP83220E”, “ELECTRONIC ATTEN”. Query Syntax *OPT? Return Syntax Where = “0,0,0,0,0,0” with no options installed Example Here are two examples of possible return strings for a fully loaded instrument.

An instrument setup must have been stored previously in the specified register. Registers 0 through 99 are general purpose and can be used with the *SAV command. Command Syntax *RCL Where = 0 through 99 though the total number of registers used may be limited by the amount of memory available.
IEEE 488.2 Common Commands *RST (Reset) *RST (Reset) Description The *RST command places the instrument in a known state.
IEEE 488.2 Common Commands *SAV (Save) *SAV (Save) Description The *SAV command stores the current state of the instrument in an internal save register. The data parameter is the number of the save register where the data will be saved. Internal registers 0 through 99 are valid for this command. The total number of registers which can be saved is limited by the number of settings which differ from their preset condition and the memory available.
IEEE 488.2 Common Commands *SRE (Service Request Enable) *SRE (Service Request Enable) The *SRE command sets the Service Request Enable Register bits. The Service Request Enable Register contains a mask value for the bits to be enabled in the Status Byte Register. A logic one in the Service Request Enable Register will enable the corresponding bit in the Status Byte Register, a logic zero will disable the bit. The *SRE query returns the current setting.
IEEE 488.2 Common Commands *STB? (Status Byte) *STB? (Status Byte) Description The *STB? query returns the current value of the instrument’s status byte. The RQS (request service) bit is reported on bit 6. The RQS indicates whether or not the device has at least one reason for requesting service.
IEEE 488.2 Common Commands *TST? (Test) *TST? (Test) Description NOTE The *TST query causes the instrument to perform a self-test. The result of the test will be placed in the output queue. Prior to sending this command, all front panel inputs must be disconnected. A zero indicates the test passed and a non-zero value indicates the test failed. Command Syntax *TST?
