N9069EM0E Noise Figure Measurement Application

• Added support for making pulsed noise figure measurements (2025.0501)

• Added support for noise figure measurements on N9042B UXA for frequencies > 50 GHz (2025.0501)

• Fixed issue causing DUT Profiles to not be saved properly. All DUT Profiles inherited the same frequency range of the last DUT Profile edited (XSA-51444, XSA-54927)

• Added support for U1833G USB Smart Noise Source, 500 MHz to 67 GHz (2025.0101)

• Added USB Noise Sources as a selection in the Signal Path Configuration

• Fixed issue that caused the DUT LO and System Downconverter LO to not be recalled properly after having saved a state (XSA-46536)

• Fixed issue causing 346CK40 noise source to not appear Noise Source list in the Signal Path Config (XSA-45245)

• Fixed issue preventing the deletion of the selected source in the External LO Setup menu (XSA-43265)

• Updated the “Auto Load ENR” behavior with a USB Smart Noise Source (SNS) connection when a state file is recalled. Previously, the stored ENR data in the state file was automatically applied regardless of which SNS is currently connected. Now, the ENR data is newly reloaded from the currently connected SNS

• Added H-band (220 to 330 GHz) noise figure support (VDI)

• Measurement now uses ENR at System Downconverter’s LO frequency when making a DSB measurements (XSA-32038)

• Fixed issue causing the Fixed Frequency value to not always be displayed when Freq Context is set to System Downconverter LO (XSA-31269)

• Added W-band support for 75 to 110 GHz with a Virginia Diodes Inc (VDI) down converter (2022.1201)

• Enhancement of markers to scroll along X-axis between measurement points to retrieve results (2022.1201)

• Enhancement of Frequency Context to be LO when system downconverter is in DSB mode (2022.1201)

• Increase number of points to 1301 (from 501)

• Support of U1832C and U1833C/D USB Noise Sources

• UI update for support of V3050A Signal Analyzer Frequency Extender

• Fixed issue to allow List Mode start frequencies entered manually to be above the range of the RF Input maximum when measuring downconverters. Entries entered via remote UI are OK. (XSA-26901)

• Fixed issue that caused errors when reading some *.ENR files (XSA-23842)

• New support for N9021B

• Fixed issue that caused unstable noise figure measurement values at frequencies > 3 GHz on CXA (XSA-3426)

• Fixed issue that caused current User Calibration to be invalidated the first time a SNS Noise Source is connected, even though Auto Read SNS is set to Off and noise source preference is set to Normal (XSA-5733)

• Fixed issue causing unstable calibrated trace in noise figure measurement on N9000B CXA when frequency is > 3 GHz. (XSA-3426)

• Fixed Help text on multitouch analyzers to indicate that SCPI commands [:SENSe]:NFIGure:CORRection:LOSS:BEFore|AFTer:TABLe:DATA and [:SENSe]:NFIG:CORRection:LOSS:BEFore|AFTer:TABLe:COUNt? are supported (XSA-3117)

• Fixed issue that caused NF measurements made using RBW > 4 MHz on analyzers with Opt FS1 to be approximately 0.5 dB worse than when RBW = 4 MHz is used (XSA-3757)

• Fixed issue for NFA-B SNS that caused noise source write functionality to be dysfunctional (513607)

• Fixed issue where Instrument Noise Figure changed after alignment or temperature change, invalidating user cal (CS1481424)

• Fixed issue in NFA-B analyzers to allow new ENR table to be written to SNS via SCPI command (513879)

• Added ability to import S2P correction files from PNA directly into Noise Figure measurement and apply them

• Added support for the U1831C USB Smart Noise Source connectivity

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.
