Agilent E1538A Enhanced Frequency/Totalize/PWM SCP 23
• <index_type> can be either of the strings "MISSing", or "EXTRa"
• <ch_list> must be the first channel on the SCP, but can contain more
than one channel provided that each channel is on a separate
E1538. See
following note. The related Error Messages are:
3110, "Channel specified is invalid for RVELocity function.
Note Only one channel on any E1538 SCP can be assigned to the
SENS:FUNC:RVEL function, and it must be the first channel on the SCP."
Example of Rotational Velocity Sense
Channel 40 senses RVEL and the algorithm reads and returns the velocity
value in CVT element 40
