ROUTe
The ROUTe subsystem provides a method to query the overall channel list definition
for its sequence of channels.
Subsystem Syntax
ROUTe
:SEQuence
:DEFine?
:POINts?
ROUTe:SEQuence:DEFine?
ROUTe:SEQuence:DEFine? < type > returns the sequence of channels defined in
the scan list.
Parameters
Comments
•
The channel list contents and sequence are determined primarily by channel
references in the algorithms currently defined. The SENS:REF:CHANNELS,
and SENS:CHAN:SETTLING commands also effect the scan list contents.
•
The <type> parameter selects which channel list will be queried:
"AIN" selects the Analog Input channel list (this is the Scan List).
"AOUT" selects the Analog Output channel list.
"DIN" selects the Digital Input channel list.
"DOUT" selects the Digital Output channel list.
•
Returned Value: Definite Length Arbitrary Block Data format. This data
return format is explained in “Arbitrary Block Program and Response Data”
on page 160. Each value is 2 bytes in length (the C-SCPI data type is an int16
array).
•
*RST Condition: To supply the necessary time delay before Digital inputs are
read, the analog input (AIN) scan list contains eight entries for channel 0
(100).This minimum delay is maintained by replacing these default channels
as others are defined in algorithms. After algorithm definition, if some delay is
still required, there will be repeat entries of the last channel referenced by an
algorithm. The three other lists contain no channels.
