Scanning
For remote operation, scanning is normally performed with continuous initiation disabled
(INIT:CONT OFF). The sample count (SAMP:COUNt) specifies the number of channels
to scan and store in the buffers (sample buffer and data store) and the trigger count
(TRIG:COUNt) specifies the number of scans to perform. Note that if the trigger count is
>1, the data for each subsequent scan will overwrite the data stored in the sample buffer
and data store.
7702 module scanning
Once the scan is properly configured, INIT or READ? will start the scan. READ? also
returns the scanned readings (data arrays) from the sample buffer or the CALC1 block if
Math is enabled. FETCh? will not start a scan, but it will return the readings already
stored.
While a scan is in process, SENS:DATA? and CALC1:DATA? commands can be used to
return the latest data array. When used after the scan is finished, they will return the data
array for the last stored reading.
7751/7752/7753 module scanning
Once the memory pattern locations and the scan are properly configured, INIT or READ?
will start the scan. READ? also returns the scanned memory patterns readings. FETCh?
will not start a scan, but it will return the readings already stored.
