new features

• Increase external trigger delay, ranging from 0-10s
• Add command: SYSTem: OVERload: TIME? Read the time of the last overload occurrence

• Add DTF support for saving CSV files, VNA support for saving S1P files

Enhanced functionality

• Change the maximum number of VNA points to 10001
• The minimum value of the VNA circle chart scale has been changed to 0.001
• Change the menu Sqrt Nyquist to Root Raised Cosine and Nyquist to Raised Cosine in the MA Filter Type, consistent with the SCPI command
• Add a line to display product model and version number when saving CSV file, and print frequency accurate to 1Hz
• The MA mode has upgraded the filter and optimized the low-frequency demodulation performance
• The default rbw/step for EMI mode has been changed from 1.0 to 3.0

Problem solved:

• SA marker and peak values are sometimes inconsistent; Marker style modification, with labels displayed on the right side; Center freq setting error; SA limit fails and stops, which is invalid; Auto frequency deviates by one point, and changing the frequency requires Auto twice; Automatically save normalized trace after modifying parameters after normalization
• EMI mode, offset setting error; After saving std lim, exit. Pressing save will save the file to an illegal path
• Changing the IP address through the web page is invalid, and after changing the login password through the web page, it is impossible to log in
• VNA switching to non-zero scan width waveform abnormality after zero scan width calibration; Loading CSA file calibration result error; Save STA file content error; Phase measurement error; VNA mode S21 calibration failed; Enhanced calibration failure
