ROUTe:CHANnel:VERify:POLarity
Syntax
ROUTe:CHANnel:VERify:POLarity <polarity>, (@<ch_list>)
ROUTe:CHANnel:VERify:POLarity? (@<ch_list>)
Description
This command sets the logic polarity of the position indicator lines on the specified channels on the 34945A Microwave Switch/Attenuator Driver. The verification feature relies on the position indicator lines to indicate the state of the switch. You can specify the polarity as "normal" (active high, indicating "closed") or "inverted" (active low, indicating "closed").
Used With:
34945A Microwave Switch/Attenuator Driver

Remarks
Use the ROUTe:CHANnel:VERify[:ENABle] command to enable verification when channels are opened or closed.
The default logic polarity is evaluated when the following commands are issued:
The ROUTe:RMODule:BANK:PRESet command restores the polarity to its default for the Distribution Board type in use. See the Agilent 34980A User's Guide for more information.
The SYSTem:RMODule:RESet command restores the polarity to NORMal for all channels.
When two channels are paired, both channels of the pair assume the polarity of the lower numbered channel.
The logic polarity setting for each channel is stored in non-volatile memory on the 34945EXT remote module.
Return Format
The query command returns "NORM" or "INV" for the specified channels. Multiple responses are separated by commas.
Examples
The following command selects an inverted polarity (active low) for channels 01 and 05 on Bank 2 on 34945EXT remote module #2 (slot 3).
