SIGLENT Remote Manual
7 SDM3055/SDM3055A
1.2. FETCh?
Waits for measurements to complete and copies all available measurements to the
instrument's output buffer. The readings remain in reading memory.
Parameter Typical Return
(none)
-5.75122019E-04, -5.77518360E-04,
-5.73923848E-04, -5.76020647E-04
Set the trigger source for immediate trigger,the INIT command will instrument in
"waiting for trigger" state, in the immediate trigger condition, measurements will
immediately be triggered and the measurement results are sent to the
measurement of memory,The FETCh? query transfers the measurement from
reading memory to the
instrument's output buffer.
TRIG:SOUR IMM //Set the trigger source for immediate trigger
TRIG:COUN 10 //Set the trigger source for 10 times
INIT //Set the trigger state for “wait for trigger”
FETC? //Read the resulting measurement value
The FETch? query does not erase measurements from the reading memory. You can
send the query multiple times to retrieve the same data.
You can store up to 1,000 measurements in the reading memory of theSDM3055x . If
reading memory overflows, new measurements will overwrite the oldest
measurements stored; the most recent measurements are always preserved. No
error is generated, but the Reading Mem Ovfl bit (bit 14) is set in the Questionable
Data Register's condition register (see Status System Introduction).
The instrument clears all measurements from reading memory when the
measurement configuration changes, or when any of these commands is executed:
