ROUTe:SCAN (@<ch_list>)
ROUTe:SCAN?
The command will disable the DMM Digitize data acquisition mode and the instrument will be in Scan mode.
However, no error will be generated when you send this command in DMM Digitize mode.
Selects the channels to be included in the scan list. This command is used in conjunction with the CONFigure com-
mands to set up an automated scan. The specified channels supersede any channels previously defined to be part of
the scan list. To start the scan, use the INITiate or READ? command.
Parameter Typical return
(none) (none)
Use CONFigure command to configure two channels for DC voltage measurements. The ROUTe:SCAN command puts the two channels
into the scan list (and redefines the scan list). The INITiate command places the instrument in the "wait-for-trigger" state and then sends
the readings to reading memory. The FETCh? command transfers the readings from reading memory to the instrument's output buffer.

The query returns a list of channel numbers in definite-length block format. The syntax is a pound sign (#) followed
by a non-zero digit representing the number of characters to follow. This digit is followed by a decimal integer indic-
ating the number of data bytes to follow. This is followed by a block of data containing the specified number of
bytes. An empty scan list (one with no channels selected) will indicated by "#13(@)"
For example:
– To remove all channels from the present scan list, issue the command ROUT:SCAN (@).
– The instrument scans the list of channels in ascending order from slot 1 through slot 3 (channels are re-ordered
as needed).When you specify a range of channels in the <ch_list>, the channels are always sorted in ascending
order. Therefore, (@109:101) will always be interpreted as 101, 102, 103,..., 109.
– You can use either the internal DMM or an external instrument to make measurements of your configured chan-
nels. However, the DAQ970A/DAQ973A allows only one scan list at a time; you cannot scan some channels using
the internal DMM and others using an external instrument. Readings are stored in DAQ970A/DAQ973A reading
memory only when the internal DMM is used.
