Notice:
This firmware must be upgraded from V3.2.2.4.0 or later. If your analyzer has an earlier version,please update to V3.2.2.4.0 first and then proceed to update to the latest version.
New Functionality:
• VNA mode Ecal add Ecal Check, S11 Ecal, S21 Ecal. Add SCPI Command for Ecal Check
[:SENSe#]:CORRection:ECAL:CONFidence:CHECk. Add SCPI Command for PV test
[:SENSe#]:CORRection:ECAL:S11:PVTest, [:SENSe#]:CORRection:ECAL:S21:PVTest
Improvements:
• Display the exit command in Remote Control mode interface.
• SA/EMI/MA mode saves the current trace when saving user configuration
• SA mode auto tune does not change the amplitude Unit and Scale Type (Log/Linear)
• EMI mode exports Freq Interpoaltion (Log/Linear) when saving lmt file, and import the configuration when recalling the lmt file.
Solved Issues:
• Fix the problem of MA mode setting the SCPI command for filter type:
DDEMod:FILTer:MEASurement setting root raised cosine and raised cosine failed.
• Fix the problem that when the EMI mode does not have touch screen function, it is impossible to pull down to see more measurement results
• Fix the problem of unit error when the command DISPlay:WINDow:TRACe:Y:SCALe:RLEVel for setting the reference level in the RTSA mode does not contain units
• Fix the problem that when the RTSA mode’s Persistence state is infinite, using the command DISPlay:VIEW:DENSity:PERSistence can still set the Persistence time
