<ch_list>
Channel
List
One or more channels (only for the
multiplexer channels), the rules are as
follows:
(@101): channel 01 on the module in Slot1;
(@101:103): channel 01 through 03 on the
module in Slot1;
(@101:103,301,406:408): channel 01
through 03 on the module in Slot1, channel
01 on the module in Slot3 and channel 06
through 08 on the module in Slot4.
If the
parameter is
omitted, this
command will
be applied to
the whole scan
list.
Explanation  Channel delay is the time interval between two neighboring channels during a scan as
shown in the figure below. During the scan, the instrument immediately disconnects
the previous channel and closes the current channel after finishing measuring the
previous channel; and then, starts measuring the current channel after the specified
channel delay.
 You can select a unique delay for each channel on the module. The default channel
delay is automatic; the instrument determines the delay based on the measurement
function, range, integration time and AC filter setting.
 The channel delay is only valid during a scan.
 The
CONFigure Command Subsystem and MEASure Command Subsystem commands
set the channel delay to automatic.
 The instrument sets the channel delay to automatic after a Factory Reset (the
*RST
command). An Instrument Preset (the
SYSTem:PRESet command) or Card Reset (the
SYSTem:CPON command) does not affect the current channel delay setting.
Return
Format
The query returns the delays of the specified channels in scientific notation. Multiple return
values are separated by commas.
Example ROUT:CHAN:DEL 5,(@213,215)
ROUT:CHAN:DEL? (@213,215)
Tquery returns +5.00000000E+00,+5.00000000E+00.
