Description

This command adds or removes relays from the “sense list”, the list of relays for which sensing is enabled.

This command only works with relays that have the ability to sense the state of the switch. Refer to the list of Agilent compatible switches and attenuators that have this capability.

In systems without CMOS RAM it is necessary to execute a write to EEROM to ensure that the VERify data will survive a power cycle. Refer to the MEM:SAVE command.

Example Command ROUTE:VERIFY:ON (@101,103,105);

This command adds channels 1, 3, and 5 on card 1 to the "sense list" . Due to the nature of sensing relays, enabling this sensing mode of operation may increase switching times, as the sense lines must settle after the switch is thrown. The default sensing delay is 20 ms. Refer to the command :DELay

to adjust switching time when sensing is enabled.

With sensing on for a given switch, if that switch fails to switch, either on a ROUTe command or on *TST?, an error is generated. Furthermore, after any switching operation, all of the relays for which sensing is on (and for which DRIVe is also on) have their sense lines checked; erroneous values generate errors.

ROUTE:VERIFY:OFF (@101,103,105);

This command removes channels 1, 3, and 5 on card 1 from the "sense list" .
