LabVIEW
Spectrum Bandwidth 6dB Limits
Equipment: E4440A Spectrum Analyzer
Software: Labview, required driver all downloaded already
Connection: GPIB-USB-HS
- So my objective is to write a labview program to auto do setting on this equipment, where values like Span, Res BW, VBW and Sweep are constant.
- The only 2 controls at front panel are Center Freq and Ref Lvl.
- After the wavefrom is produced, my labview program will capture a screenshot and save in my PC.
the photo below is the steps:
➡️➡️➡️➡️➡️ So what i need help is: part (g) ⬅️⬅️⬅️⬅️⬅️
How do i get the peak value.
Use the peak value minus by 6 = X
Then, use X to draw a straight horizontal limit line
Find the 2 intersection point of the waveform and the limit line.
