Measuring Channel Select
Choose channel selection for channels to be recorded
The channels to be recorded are selected with this
command. MCS cannot be used for selection during data
acquisition. In this case, the command is acknowledged
with a "?". The query command is also possible during
recording.
MCS p1,.., pxx (x)
p1,.., pxx 1,.., xx Channel selection
MCS 0 (x) selects all the existing channels
MCS (x) deselects all channels
Channels 17, 18 and 19 are the internal time stamps. The
time stamp is a 6‐byte counter with a rate of approx.
153,640 Hz. Time channels 17, 18 and 19 do not appear
in commands PCS?/SPS?. Times do not have
subchannel realizations (SMS command).
The binary ("measurement") data have a length of 8
bytes, where the highest valued two bytes are zero.
Time data are always placed at the end of one measval
line.
There is an implicit connection between the Sample rate
group and the three time channels:
Channel 17: Sample rate group 0
Channel 18: Sample rate group 1
Channel 19: Sample rate group 2
The response depends on the SRB command. Have a
look at STF and NTP command too. The multi IO‐card
PX878 is not selectable here. It does not create measure­
ment values.
