Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual

13-6 3700S-901-01 Rev. C / July 2008

Logical instruments also look like TSP tables. In addition to the logical

instrument-specific attributes and the commands to which they respond, there

are a few attributes that provide information about the logical instrument. These

attributes are listed below:

name: A string that represents the logical instrument's name. For example,

dmm.

node: A reference to the TSP-Link

node of which the logical instrument is a

part. Default value is 2.

Query commands

Channel response query commands can return a comma-delimited string (for

example, channel.getcount and other channel response query commands).

When a channel query command like channel.getcount or

channel.getstate is sent, the response is a comma-delimited list. The list

starts with the lowest channel through to the highest. After the channels are

listed, the analog backplane relays are listed, starting with Bank 1 followed by

each subsequent bank.

For example (Model 3720 card installed in Slot 4, returning 72 comma-

delimited values):

Send the following command:

print(channel.getclose('slot4'))

The first 60 values returned are for Channels 1 to 60, starting with 1 and

increasing to 60. The next six values are for analog backplane relays in Bank 1

(starting at 1 and increasing to 6). The final 6 values are for analog backplane

relays in Bank 2 (again, starting at 1 and increasing to 6).
