Return Format
The command returns a value between 0 and the maximum number of scanned channels in the 34980A (up to 640 channels). Since the non-sequential scanning mode allows duplicate channels in the scan list (see ROUTe:SCAN:ORDered command), each occurrence of a channel is counted and included in the returned value.
