3.7.7 Reading the 'ELCH' status
There are several possibilities to see whether the 'ELCH' measurement sequence is
still running or not:
•
Query the ELCH status directly:
":ELCH:RUN?"
(time consuming, especially if
the ELCH sequence is still running)
•
Read the Block Function Event Register of the PRO8000. If ELCH has finished,
bit 1 is set to 1 (
":STAT:BFR?"
)
•
If enabled via the Block Function Enable Register, read bit 2 of the Status byte
(faster)
"*STB?"
•
If enabled via the Service Request Register, trigger a service request (takes no
additional time)
•
Poll the status byte with the low level IEEE 488 messages serial poll sequence
SPE and SPD (refer to IEEE 488, section 2.5.1)
3.7.8 Reading the measured values
With the command:
:ELCH:TRIG?
You can step through the list of measured values.
If you use this command more often than measurement-steps have been defined,
you will get the last answer string again and again.
Example of an answer string:
7.12345678E-003,6.94673825E-002,1.00000<LF>
