Analog IF Input Detector Adjustment Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Analog IF Input Detector Adjustment The adjustment determines the power detected by the A8 Analog IF (AIF) input power detector under known conditions. The detector gives a DC level which corresponds to this power. An ADC converts this DC level to a digital value which is then stored in the A8 EEPROM. The 321.4 MHz calibrator on the A10 Third Converter is used to provide a stable -7 dBm, 21.

YTF Alignment (RYTHM and SBTX) Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software YTF Alignment (RYTHM and SBTX) The instrument firmware tunes the YTF (Yig Tunable Filter) via a DAC. The relationship between DAC value and tuned center frequency follows a 3rd order polynomial curve. The non-linearity of this curve is enough to offset the center frequency of this filter by several tens of MHz. This alignment calculates the coefficients of the 3rd order polynomial.

Frequency Response Adjustment Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Frequency Response Adjustment This adjustment procedure performs the following steps: The instrument’s internal flatness corrections are turned off. Amplitude error as a function of frequency from 9 kHz to 26.5 GHz is measured and normalized to the 50 MHz measurement. Predetermined frequency points are used when testing from 9 kHz to 50 MHz and 3 GHz to 26.5 GHz.
Frequency Response Adjustment Two sources, and two sets of power sensors are used to provide the needed frequency range. To measure frequencies below 100 kHz, a DVM with a 50 ohm load replaces the power sensor and a function generator is used as the source. For improved amplitude accuracy below 3 GHz, the power splitter is characterized using a specially-calibrated power sensor (the “reference” sensor) connected to one power splitter output port.

Troubleshooting Test Failures Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Troubleshooting Test Failures If a test will not proceed, then suspect either the setup is incorrect, or the test equipment or DUT is faulty. Specifically you should: ● ● ● ● Compare your test connections with the test setup on the computer screen. Ensure the cables and adapters are correct and not damaged. Check the output and input connectors on the test equipment for damage.

Residual Responses Troubleshooting Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Residual Responses Troubleshooting Related Adjustments ● None If the residuals test fails, check the results of the DANL TEST. If DANL is out of spec, there is a good possibility that the high average noise level is causing the residuals test to indicate a false failure. Also assure the 50 ohm load is attached to the analyzer RF Input connector.
Displayed Average Noise Level Troubleshooting Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Displayed Average Noise Level Troubleshooting Related Adjustments ● None An increase in the Displayed Average Noise level is often the result of incorrect gain in the signal path.

Gain Compression Troubleshooting Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Gain Compression Troubleshooting Related Adjustments ● ● ● Lowband Mixer Bias Adjustment Switched LO Distribution Amplifier Adjustment Second LO Power Adjustment Failures can be caused by the A20 Lowband assembly or the or the A10 3rd Converter.

IF Amplitude Ripple Troubleshooting Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software IF Amplitude Ripple Troubleshooting Related Adjustments ● None If the IF Amplitude Ripple Test fails, the most likely caused by the A8 Analog IF. Less likely is the A10 Third Converter or A7 Digital IF. http://mktwww.soco.agilent.com/field/lp/PSA/PSAcalSWwebhelp/Troubleshooting/troubleifamprip.
IF Phase Ripple Troubleshooting Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software IF Phase Ripple Troubleshooting Related Adjustments ● None A failure of the IF Phase Ripple test would most likely be the A12 synthesizer board, provided the other tests passed. http://mktwww.soco.agilent.com/field/lp/PSA/PSAcalSWwebhelp/Troubleshooting/troubleifphaserip.
Input Attenuation Switching Uncertainty Troubleshooting Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Input Attenuation Switching Uncertainty Troubleshooting Related Adjustments ● None A faulty attenuator (A14 or A15) will cause this to fail. A second possible cause can be the A13 Front End Driver not properly driving an attenuator. NOTE: This test might fail due to incorrect calibration data of the 8494 and 8496 step attenuators.
Display Scale Fidelity Troubleshooting Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Display Scale Fidelity Troubleshooting Related Adjustments ● None If this test fails at input power levels greater than -15 dBm, suspect the A8 Analog IF Assembly (gain compression), or possibly the A7 Digital IF Assembly. Failures at input power levels of less than -15 dBm may be caused by the A7 Digital IF Assembly (ADC).
Absolute Amplitude Accuracy Troubleshooting Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Absolute Amplitude Accuracy Troubleshooting Related Adjustments ● ● ● 50 MHz Calibrator Amplitude Adjustment Switched LO Distribution Amplifier Adjustment Second LO Power Adjustment Perform the 50 MHz Calibrator Adjustment if this test fails.

Noise Sidebands Troubleshooting Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Noise Sidebands Troubleshooting Related Adjustments ● None If the Noise Sidebands test fails, check the results of the DANL TEST. If DANL is out of spec, there is a good possibility that the high average noise level is causing the noise sidebands test to indicate a false failure. Phase Noise is a parameter that describes short term instability of LO tune frequency.
Noise Sidebands Troubleshooting Oscillator (OCXO) on the A11 Reference Board. Failures at other offsets can be caused by the A12 Synthesizer Assembly. See the PSA Service Guide for troubleshooting information on how to determine which half of the A12 Synthesizer assembly is at fault. Another, but least likely, assembly that could cause a Phase Noise failure would be the A13 Front End Driver assembly. http://mktwww.soco.agilent.com/field/lp/PSA/PSAcalSWwebhelp/Troubleshooting/troublenoisesb.
Frequency Response Troubleshooting Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Frequency Response Troubleshooting Related Adjustments ● Frequency Response Adjustment If the Frequency Response Test fails by a small amount (5 dB or less) the instrument can probably be fixed by performing the Flatness Adjustment. If an adjustment cannot fix the problem, or the test fails by a large error (5 dB or more), this would indicate a faulty assembly.
Frequency Response Troubleshooting If the frequency response test fails at frequencies below 3 GHz (Low band), the following should be done: Perform the Frequency Response Adjustment in its entirety. If the adjustment does not fix the problem, or the adjustment cannot complete, suspect a hardware problem. Major assemblies to suspect are: The A20 Lowband Assy, the optional A22 Lowband preamp, optional A27 Electronic attenuator, or the A13 Front End Driver circuits that control the assemblies listed.
Option 266/Basic Mode Conflicts Agilent Technologies PSA Series Spectrum Analyzers Test and Adjustment Software Option 266/Basic Mode Conflicts The A.03.xx release of PSA firmware introduced Option 266 (8566 code compatibility). It was discovered that Option 266 I/O commands collided with the Basic Mode I/O. Since it was reasonable to assume that Basic Mode (with Option B7J for digital comms measurements) and Option 266 would not be needed at the same time, there were two firmware builds created.
