VXi VT1422A Manuale Utente

Examples:
     On-board channels 0 through 15=100:115
     Remote channels 0000 through 0131=10000:10131
     
By using commas to separate them, individual and range 
specifications can be combined into a single channel list:
     0, 5, 8 through 3331 and 45=(@100,105,108:13331,145)
Notice that the range specified (108:13331) included a mix of 
on-board channels as well as remote channels. The VT1422A 
will correctly address all channels in the range according to the 
type of SCP installed at the channel position (remote for 
VT1539A SCPs and on-board for all other SCP models).

When a channel range includes both on-board and remote channel references, the 
command that specifies this range must be applicable to the function of the SCPs 
installed at those addresses or a 3007 "Invalid signal conditioning plug-on" error will 
be generated.

The standard SCPI Relative Channel specification syntax is:
(@cc(nn,nn,nn:nn ... ))
where cc = card number and nn = channel number. Notice that 
with this form the card number digit moves from in front of each 
channel number, to outside of the inner parentheses.
Example:

0, 5, 6 through 32 and 45 = (@1(0,5,6:32,45))

The Relative form has special meaning when used in the 
VT1422A’s ROUTe:SEQuence:DEFine (@<ch_list>) 
command. For the VT1422A, the syntax changes to:
(@d(1nn,1nnee,1nn:1nn,1nn:1nnee,1nnee:1nnee,1nnee:1nn ...) 
Notice that cc (standard form card number) has changed to d
where d is now the "Data Destination" digit. The value of d 
controls the destination of the values read from the specified 
channels in the following manner:

Getting back to the relative channel syntax above, notice also 
that all channels start with "1."
