Good day,
I am generating 16 GHz pulses using a mixer connected to a AWG and LO and I measured the power using a spectrum analyzer in time domain.
I encountered several comments from someone with more experience but I could not get further explanation from him.
I am a new in this field and I would like to ask the opinions of gurus in this field about his opinions.
He suggested me to:
1. each instrument is has phase noise so I should lock the phases of the instruments to minimize phase error. A maximum of about 3 dB error may occur if i did not do that. The AWG 10 MHz REF_IN is connected to the LO's REF_OUT but not to the spectrum analyzer.
2. The pulse width is 3 us and the PRF is 100 Hz. The RBW of 10 MHz is insufficient to accurately determine the power of such pulses.
I would like to know more about his comments but I am still doing a lot of hunting and I cannot really find the answer to these questions.
I might be searching in the wrong documents.
Would anyone be kind enough to shed some light or point me to the right direction please?
Thank you in advance.
