258 HP E1419 Command Reference
The ROUTe subsystem provides a method to query the overall channel list
definition for its sequence of channels.

ROUTe

:SEQuence
:DEFine?
:POINts?
ROUTe:SEQuence:DEFine? <type> returns the sequence of channels defined in the
scan list.
Parameter Parameter
Name Type
type (string)
•
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 Data" on page 6-185 of this
chapter. 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.
