•<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."
