Hi all,
I did a measurement on my 26MHz crystal oscilator and found something strange with different setting as below:
with ref level set to 10 dbm i got the weird measurement with a lot of sideband ripples. Did i over compress my signal? But the power lvl is only -13.67dbm, i assume using ref lvl 10 dbm is ok.
with ref level set to 20 dbm, i get a cleaner output.
Anyone tell me which setting is correct? or something wrong with my crystal oscilator output. thanks.
regards
Bao
