What's the meaning of MCA Read Rate and MCA Status Rate? What's the influence when change them? #13

Does MCA Read Rate means the rate of MCA spectra to be read and MCA Status Rate means the rate of MCA status to be read?

MCA status is same as the detector status, right?

If I set them to periodically process(e.g. "1 second"), the MCA status and MCA spectra will be read periodically(i.e. "1 second"). If I set them to passive, the MCA status and MCA spectra will be read once when acquisition completes.

If I set MCA Read Rate and MCA Status Rate to periodically process, will them be read when acquisition completes?

Will different settings about MCA Status rate and MCA Read Rate affect the detector's data quality?

This makes me a little confused. Looking forward to your reply. Thanks!

Yes.

It is things like elapsed real time, elapsed live time, other statistics, etc.

Yes.

Yes.

Yes.

No.

It is documented here: https://epics-modules.github.io/dxp/dxpDoc.html#dxpMED

Look for StatusAll and ReadAll.

OK, Thanks very much.
