N9068EM0E Phase Noise Measurement Application

• Added support for Total Discrete Jitter and Random Jitter results to Log Plot measurement (2025.0501)

• Added support for N9042B-575, Frequency Range 2 Hz to 75 GHz

• Added support for spurious search parameters

• Fixed issue causing Help to not be available for Trace controls (XSA-42122)

• Fixed issue in Log Plot measurement which resulted in amplitude corrections not being applied in the FFT region (XSA-38995)

• Fixed issue causing the Auto/Man value for Signal Tracking Span to not be shared between measurements (XSA-31006)

• Fixed issue in Log Plot measurement that prevented the ADC Clipping message from appearing when the AM Rejection offset is set to a value >> 1 MHz (e.g. 40 MHz) (XSA-34282)

• Fixed issue that caused Log Plot measurements to be much slower on N9000B CXA analyzers (XSA-32305)

• In several measurements, corrected the SCPI command that appears when pressing Show SCPI command. For example, in Log Plot measurement, “:SENSe:FREQuency:CENTer <value>” should be “:SENSe:FREQuency:CARRier <value>” (XSA-32736)

• Fixed result of SYST:HELP:HEAD? query to return both CENTer and CARRier mnemonics (XSA-31808)

• Fixed issue that caused Log Plot measurement to limit the maximum Rejection Offset to 500 MHz on analyzers that had analysis bandwidth of 2 GHz (XSA-18060)

• Fixed issue in Log Plog measurement that caused the attenuator in the V3050A Frequency Extender to not be set properly (XSA-21891)

• Allowed selection of either Auto Align Partial or Auto Align Normal when ADJIF ON command is sent (XSA-17257)

• Fixed issue that caused a NullReferenceException to occur when switching from SA mode to Phase Noise mode (XSA-16079)

• Fixed issue in Log Plot measurement that caused large false spur to appear when changing the number of sweep points to large values (for example, >4000) (XSA-9757)

• In Log Plot measurement, fixed minor error between integrated noise marker values reported in dBc compared to values reported in degrees, radians, or seconds (jitter) (515294)

• In Log Plot measurement, fixed calculation of Residual FM, which could report 22% higher than the true value (527110)

• Fixed issue in Log Plot measurement that caused Signal Tracking to not track well when slow FM is applied to a CW signal under test and AM Rejection is ON (520873)

• Fixed issue in Log Plot measurement that caused the application to crash if the decade table was enabled and the results were read back using “READ:LPL6?” SCPI command (512460)

• Added PM Rejection feature, which rejects PM phase noise contribution, thus showing AM phase noise contribution. This is a complementary feature to the existing AM Rejection feature.

• Added ability to save Marker Table results to the Save, Measurement Data menu for the Log Plot measurement.

• In Log Plot measurement, added support for trace hold type Max Hold and Min Hold selection in the Trace Control menu

• In Log Plot measurement, added support for trace filtering function with High Cutoff Freq, High Cutoff Slope, Low Cutoff Freq, and Low Cutoff Slope in the Trace menu

NOTE:

A.20.22 fixes the defect found in instrument software versions A.20.03 and A.20.04 that caused measurement accuracy issues. Any analyzer running A.20.03 or A.20.04 should be upgraded to A.20.22 or later.
