how to read a spectrum analyzer
Dear all,
I'm new to spectrum analyzer and having difficulty to calculate the measured signal voltage received by spectrum analyzer. Here's the case :
- I tap a signal to an oscilloscope and it read 2 Vpp
- I tap the signal to a spectrum analyzer and it read -23.37 dBm in a 50 ohm system.
My calculation for -23.37 dBm is about 0.42 Vpp.
Is there something wrong I did in my calculation or there is something else I didn't consider in my measurement using spectrum analyzer?
FYI, I forget to mention that there is 20 dB Attenuation measurement result in spectrum analyzer'.
