Troubleshooting How to Return Your Analyzer for Service Figure 4-1 4-8 Chapter 4
Troubleshooting How to Return Your Analyzer for Service Other Packaging CAUTION Analyzer damage can result from using packaging materials other than those specified. Never use styrene pellets in any shape as packaging materials. They do not adequately cushion the equipment or prevent it from shifting in the carton. They cause equipment damage by generating static electricity and by lodging in the analyzer louvers, blocking airflow.
Troubleshooting Error Messages Error Messages The analyzer can generate various messages that appear on the display during operation. There are four types of messages. • Status Messages appear on the right side of the analyzer display and/or set status bits in the SCPI Status Register system. These messages indicate a condition that may result in erroneous data being displayed. Most messages will only be displayed until the error condition is corrected.
Troubleshooting Status Messages Status Messages The following messages indicate a condition that may result in erroneous data being displayed. In each case the name of the corresponding status bit is indicated in parenthesis. It will be noted if only a status bit is used (no message). * (Invalid Data) This indicator is displayed when data on the screen may not match the screen annotation, for example while analyzer settings are changing or when any trace is in view mode.
Troubleshooting Status Messages E4411B only: disconnect any signals from the INPUT prior to performing this procedure. Align RF Skipped (Align RF Skipped) The RF alignment has been skipped because a 50 MHz signal was detected at the INPUT; alignment will resume when the 50 MHz signal is removed. The alignment will not work when there is too much input power at 50 MHz. The instrument may not continue to measure properly. To remove the message, remove the 50 MHz input signal, then perform an Align Now, RF.
Troubleshooting Status Messages Input is internal (no corresponding status bit) This message applies to the Agilent Technologies E4401B and E4411B only. Indicates the 50 MHz Amptd Ref selection is On. With the 50 MHz amplitude reference on, the input is routed through an internal signal path. (LO Align Failure) status bit only, no message A failure has occurred during the alignment of the local oscillator (LO). Measurement results may be invalid.
Troubleshooting Status Messages Overload: Reduce Signal and press (Input Overload Tripped) This message applies to the Agilent Technologies E4401B and E4411B only. A signal has been applied to the input connector that caused the overload protection circuitry to engage. The input signal must be reduced. After the signal is reduced, press ESC to reset the overload detector so that you can continue using the analyzer.
Troubleshooting Status Messages Source Unlevel (Source Unleveled) Indicates the source power is set higher or lower than the analyzer can provide, the frequency span extends beyond the specified frequency range of the tracking generator, or the calibration data for the source is incorrect. (TG Align Failure) status bit only, no message A failure has occurred during the tracking generator (TG) alignment.
Troubleshooting Informational Messages Informational Messages The following messages provide information that requires no intervention. The information provided in brackets, for example or , is a variable that represents a specific input provided previously. Informational messages are displayed at the bottom of the screen in the status line (green on color displays). directory deleted The directory indicated has been successfully deleted.
Troubleshooting Informational Messages Atten auto set to 15 dB Indicates that an input signal has been detected which is of sufficient level to force the input attenuator to be autocoupled at 15 dB. If the signal level is reduced, the attenuator will stay at 15 dB. This overload protection occurs at an input power level of 13 dBm (68 dBmV for Option 1DP) and ± 7 dB when the input attenuation is autocoupled and set to <15 dB.
Troubleshooting Informational Messages Default spur table values loaded. No spur table has been previously saved when the Out-of-Band Spurious measurement begins. Press Meas Setup, Edit Table to enter the frequency ranges of interest and press Save Table to save that information. This saved table will be loaded the next time the measurement is run. Device = Mobile. Code Domain not available. Code Domain measurement is grayed out when the device is set to mobile under the Mode Setup front-panel key.
Troubleshooting Informational Messages Measurement halted. Press a measurement key to continue. This error occurs after you choose Cancel to refrain from setting the attenuator to 0 dB during the Receive Channel Power and Receive Spur measurements. Not enough frequency range to measure harmonics for channel. Selected harmonics are above the frequency range of the instrument. Option activated This message is displayed after entering the selected option’s License Key.
Troubleshooting Informational Messages Table saved successfully. This message appears after the user presses the Save Table key on the second page of the edit table for the out-of-band spurious measurement. It indicates that the current spur table has been written successfully to disk and is available to be loaded by means of the Load Table key. Volume formatted The indicated disk has been successfully formatted. The calibration data is invalid, and has been cleared.
Troubleshooting Error Queues Error Queues When a user-error condition occurs in the instrument as a result of SCPI (remote interface) activity, it is reported to both the front-panel display error-queue and the SCPI error queue. If it is a result of front-panel activity, it reports to the front panel display error queue, and may also report to the SCPI error queue depending on the error. These two queues are viewed and managed separately.
Troubleshooting Error Message Format Error Message Format The system–defined error numbers are chosen on an enumerated (“1 of N”) basis. The error messages are listed in alphabetical order within each error message type section. In this chapter, an explanation is included with each error to further 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.
Troubleshooting Error Message Types Error Message Types Events do not generate more than one type of error. For example, an event that generates a query error will not generate a device-specific, execution, or command error. –499 to –400: Query Errors These errors indicate that the instrument output queue control has detected a problem with the message exchange protocol described in IEEE 488.2, Chapter 6. Errors in this class set the query error bit (bit 2) in the event status register (IEEE 488.
Troubleshooting Error Message Types 201 to 799: Device-Specific Errors These errors indicate that a device operation did not properly complete, possibly due to an abnormal hardware or firmware condition. These codes are also used for self-test response errors. Errors in this class set the device-specific error bit (bit 3) in the event status register (IEEE 488.2, section 11.5.1). The string for a positive error is not part of the SCPI standard.
Troubleshooting 0: No Error 0: No Error 0 No error The queue is empty. Every error in the queue has been read or the queue was purposely cleared by power-on or *CLS.
Troubleshooting –499 to –400: Query Errors –499 to –400: Query Errors The instrument output queue control has detected a problem with the message exchange protocol described 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 in IEEE 488.2, 6.5.
Troubleshooting –499 to –400: Query Errors –440 Query UNTERMINATED after indefinite response Indicates that a query was received in the same program message after a query requesting an indefinite response was executed (see IEEE 488.2, 6.3.7.5).
Troubleshooting –399 to –300: Device-Specific Error Messages –399 to –300: Device-Specific Error Messages An error number in the range [−399 to −300] indicates that the instrument has detected an error where some device operations did not properly complete, possibly due to an abnormal hardware or firmware condition. This is not a error in response to a SCPI query or command, or command execution.
Troubleshooting –299 to –200: Execution Error Messages –299 to –200: Execution Error Messages An error number in the range [–299 to –200] indicates that an error has been detected during instrument execution. Execution Error Message Descriptions –221 Settings conflict; parameter currently disabled This parameter is grayed out (unavailable) in the current context. Check the individual parameter help/documentation for more information.
Troubleshooting –199 to –100: Command Errors –199 to –100: Command Errors The instrument 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: • Either an IEEE 488.2 syntax error has been detected by the parser (a control-to-device message was received that is in violation of the IEEE 488.2 standard.
Troubleshooting –199 to –100: Command Errors –100 Command error This is a generic syntax error for devices that cannot detect more specific errors. The code indicates only that a command error as defined in IEEE 488.2, 11.5.1.1.4 has occurred. –110 Command header error An error was detected in the header.

The maximum number is 10.
Front-Panel Key Reference MEASURE MEASURE In the Spectrum Analyzer (SA) mode, accesses a menu of keys that allow you to make adjacent channel power, channel power, occupied bandwidth, emission bandwidth, and harmonic distortion measurements. NOTE When a measurement is activated, Signal Track, Video Averaging, Segmented Sweep, Band Power and Marker Noise will be turned off.
Front-Panel Key Reference MEASURE Occupied BW Integrates the power of the displayed spectrum and puts markers at the frequencies between which a selected percentage of the power is contained. The measurement defaults to 99% of the occupied bandwidth power. The power-bandwidth routine first computes the combined power of all signal responses contained in the trace. For 99% occupied power bandwidth, markers are placed at the frequencies on either side of 99% of the power.
Front-Panel Key Reference MEASURE When measuring the Nth harmonic, the analyzer will choose the narrowest resolution bandwidth that is ≥N times the resolution bandwidth used to measure the fundamental. Widening the resolution bandwidth allows the measurement to capture all modulation on the harmonics. An asterisk (*) will appear next to the amplitude of measured harmonics for which the desired resolution bandwidth could not be set.
