Hi all,
This is EPR related question. Does anyone have ER 4122SHQE cavity in your
facility? I recently got some background signal from it and Bruker asked me
to do a background signal test. It is to test the ratio of "background
amplitude" with "weak pitch amplitude*calibration factor". If the ratio is
over 1/2, then it passes the test. If you are interested, I can send you
the procedure separately. It is different from the Signal to Noise ratio
test.
Has anyone done this test before? If you have done this, what is your value
of this ratio? In my opinion, for SHQE cavity, it is really easy to pass
this test. My ratio is about 0.04.
Thank you.
Lingchao
