The analyzer can generate various messages that appear on the displa y during operation. There are four types of messages.

• Status Me ssages, beginning on page 37, appear on the right side of

the ana ly z er display and /o r set status bit s in t h e SC PI Status Register syst e m . T hes e m e ssa ge s indicate a conditi on th at m ay result in erroneous data being displayed. Most messages will only be displayed unt il t h e error condi t ion is corre c t e d . M u lt iple messages can be displayed and will be listed in the display area. In each case the name of the corresponding status bit is indicated in parenthes i s . It will be no t e d if o n ly a st at u s bi t is u se d (n o me ssage).

• Informat ional Messages, beginning on page 42, provide information

that requires inter venti on. These messages appear in the status line at the bottom of the display. If you have a color display and are using the default display colors, the message will appear in green. The message will remain until you preset the analyzer, press anothe r messa ge is displayed in th e status lin e. The info rmatio n provided in brackets, for example <filename> or <directory>, is a variable that represents a specific input provided previously.

• User Error Messages, beginning on page 18, appear when an attempt h as been made to se t a parameter inco rre ctly or an operation has fa iled ( s uc h a s s aving a file). These messages are often generate d du ring remote op e rat ion when an invalid progra mm in g command has been entered. These messa ge s a ppe ar in the status line at the bottom of the display. If you have a color display and are using the default d isplay colors, the message will appear in yellow. The message will remain until you preset the analyzer, press

ESC, or

another message is displayed in the status line. A summary of the last 30 error messages preceded by an error number may be viewed in the Error Queue by pressing,

System then Show Errors. Refer to

Table 1-1 for more inf ormation on the characteristics of the Error

Queue. When a remote interface initiates activity that generates an error , the messages are outp ut to the remote bus. When output to the remote interface, they are preceded by an error number.

When a user error conditi on occurs in the analyzer as a result of SCPI (remote interface) activi ty, it is repor ted to both the front panel display error queue and the S CPI error queue. If i t is a res ult of front panel activity, it reports to the front panel display err or queue, and depen din g on the error, may also re po rt t o th e SCPI error que u e . These two queues are viewed and managed separately.

In this ch apter, an explanation is included with each er ro r t o fur ther clarify its meaning. The last error described in each class (for example, –400, –300, –200, –100) is a “generic” error. There are also references to the IEEE Standard 488.2-1992, IEEE Standard Codes, Formats,

Error Message Types

Events do not generate m ore than one type of error. For example, an event that generates a query error will not generate a device-specific, execution, or com m and error.

–499 to –400: Query Errors

–399 to –300:

Device-Specific Errors

–299 to –200: Execution Errors

–199 to –100: Command Errors

These errors indicate that the analyzer output queue control has detected a problem with the message exchange protocol describ ed in IEEE 488.2, Chapter 6. Errors in this class set the query error bit (bit 2) in the event status register (IEEE 488.2, section 11.5.1 ) . These errors correspond to message exchange protocol errors described i n IEEE

488.2, 6.5. In t his case:

• Either an attempt is being made to read data from the output queue when no output is either present or pending, or

• data in the output queue has been lost.

An error nu mber in the ran ge –399 to –300 indicates that the analyzer has detected an err or where some device operations did not properly complete, possibly due to an abnormal hardware or firmware condition. This is not a er ro r in re sponse to a S C PI query or command, or command execution. The oc curr enc e of a ny error in this class will cause the device-specifi c error bit (bit 3) in the event status register to be set.

These errors indicate that an error has been detected during analyzer execution.

These errors indica te that the analyzer parser detected an IEEE 488.2 syntax error. Errors in this class set the command error bit (bit 5) in the event status register (IEEE 488.2, section 11.5.1). In this case:

Instrument Messages Introduction

• Either an IEEE 488.2 synta x error has been detected by the parser (a control-to-dev ice message was received that is in violation of the IEEE 488.2 standard. Possible violations include a data element which violates dev ice listening formats or whose type is unacceptable to the device.), or

• an unrecognized header was received. These include incorrect device-specific headers and incorrect or unimplemented IEEE 488.2 common commands.

201 to 799: Device-Specific Errors

These errors indicate that a device operation did not pr op erly complete, possibly due to an abnormal hardware or firmware condition. These codes are al so u se d fo r se lf -t e st re spo n se e rro rs. Errors in this class set the device-specific error bit (bit 3) in the event status register (IEEE

488.2, s e ction 11. 5.1).

The <error_message> string for a positive error is not part of the SCPI standard. A positive error indicates that the anal yzer det ect ed an error within the GPIB system, within the analyzer firmware or hardware, during the transfer of block data, or during calibration.

What You Will Find in This Chapter

This chapter describe s t he f unct ional tes ts and pr ovi des inf or mation on how to perform them .

What Are the Functional Tests?

Functional tests are t e sts of var i o u s instrument parameters that give a high degree of confidence that the analyzer is operating correctly. They are recommended as a check of analyzer operation for incoming inspection or after a repair. Mea surement uncertainty analysis is not available for functional tests, and the analyzer is checked against limits that are wider than the published specifications. The functional tests are designed to test an analyzer operating within the temper ature range defined by the analyzer specifications using a minimum set of test equipment. If a test does not pass, performance tests must be run to confirm a proble m exists .

Functional Test Versus Performance Verification

Performance verification tests check a wide range of analyzer parameters and provide the highest level of confidence that the analyzer is opera ting satisfactorily. They are used to verify that the analyzer conforms to publi shed speci fications. They are tim e consuming and require extensive test equipment. The functional tests c heck a much smaller range of parameters and a limited number of data points for each parameter. They require only limited test equipment.

Test Descript ions

Each of the following test descriptions include the tes t limits (pass/fail criteria), a desc ription of what the test does or what it measures, a list of equipment required for the performanc e of the tes t, a n il lustr a tion o f the test setup used, and a step by step test procedure. The tests are designed to be run on an analyzer operating within the operationa l temperature range defined by the analyzer specific ations. Only perform tests after the spe ci fi ed warm-up time.

At the end of each test is a test results worksheet. Copy a worksheet to record your test re su lts for each proce du re y ou’ll be conducting.

Test Description

Scale Fidelity

A 50 MHz CW signal is applied from a synthesized sweeper to the input of the analyzer. The source is a djusted for a response at the reference level. The synthesized sweeper amplitude is adjusted to achieve a nominal amplitude below the reference level. The analyzer’s amplitude marker is compared to the actual source change to determine the scale fidelity error. Most of the err or is the source’s output attenuator inaccuracy from the synthesized sweeper.

Test Description

To test second harmonic distortion, a 50 MHz low pass filter is used to filter the sourc e output, ensuring that harmonics read by the analyzer are internally generated and not coming from the source. The source power and input attenuation on the analyzer are adjusted so –20 dBm is the power level at the first mixer.
