Agilent Technologies manual User-Defined Channel Labels, All L4400 series instruments

3Operating and Programming

•The simulation setting is stored in volatile memory and will be lost when power is turned off. To re- enable the simulation mode after power has been off, you must send the command again. The command used is:

SYSTem:ABUS:INTerlock:SIMulate {OFFON}

User-Defined Channel Labels

Usage:

•All L4400 series instruments

You can assign user- defined labels to any channel, including Analog Bus channels on the L4421A and L4433A instruments. User- defined channel labels are available for identification purposes only and cannot be used in place of a channel number within a command string.

•When shipped from the factory, each channel is assigned a unique factory- default label (cannot be overwritten). From the instruments’ Web interfaces, the factory- default labels are displayed as the channel number (e.g., “1001”, “1020”, etc.).

•If desired, you can assign the same user- defined label to multiple channels within the same module or on different modules (i.e., channel labels are not required to be unique).

•You can specify a label with up to 18 characters. You can use letters (A- Z), numbers (0- 9), and the underscore character. If you specify a label with more than the allowed 18 characters, it will be truncated (no error is generated).

•From the Web Interface, a limited number of characters can be displayed due to space constraints in the browser window. If the user- defined label it too long to be displayed properly, it will be truncated (no error is generated).

•All user- defined channel labels are stored in non- volatile memory, and do not change when power has been off, after a Factory Reset (*RST command), after an Instrument Preset (SYSTem:PRESet command), or after a stored state is recalled (*RCL command).

The following command assigns a label (“TEST_PT_1”) to channel 3 in slot 1.

ROUT:CHAN:LABEL "TEST_PT_1",(@1003)

The following command clears the user- defined label previously assigned to channel 3 in slot 1. The channel will now be identified by its factory default label (e.g., “MUX CH BANK 1”, “MATRIX1 ROW3 COL4”,

“DIO BYTE 1”, etc.).

ROUT:CHAN:LABEL "",(@1003)
