Hello everyone,

I encountered a problem with my HM5014-2 instrument.
There is dipping in my waveform. This is not usually happened.

Can you help me to figure out the problem and how to solve it?
I attach the waveform.

Thank you very much.

This is due to inappropriate instr. setting. You cannot set this three parameters independently. To solve this problem you have to do one or two of the following:
1. increase the RF BW
2. increase the sweep time
3. decrease the sweep width
I hope this helps.

First you'd have to find out if the problem remains at the same spot at all settings, or scales with span and center frequency?
Also please give more description what are you trying to measure and how?
