Description

Each channel has a CLOSE or OPEN position. On Agilent relays, the OPEN path is the path between the input terminal labeled 1 on the relay and the input terminal labeled C. It is recognized that CLOSE and OPEN are arbitrary for this type of switch; they are, however, in keeping with the SCPI language specification.

Example Command ROUTE:OPEN (@101,2(0:5),3(1,3,5),406:410);

During any switching operation (OPEN or CLOSE) the settling bit in the OPER status register is set (1). It is cleared (0) when the operation completes.

Sending the above command causes channel 1 on card 1, channels 0 through 5 on card 2, channels 1, 3 and 5 on card 3, and channels 6 through 10 on card 4 to be opened. Channels must be part of the drive list (DRIVE:ON) to be opened or they will be ignored.

Example Query ROUTE:OPEN? (@101,103,105);

Sending the query (optional question mark) causes the channels in the channel list parameter to be checked for opened channels. The readback is a list of 1’s and 0’s separated by commas, one for each channel in the list. A 1 is sent if the specified channel is opened, otherwise a 0 is sent. Although this command is not strictly necessary (ROUTE:CLOSE? is sufficient), it is included for completeness.

Devices for which sensing is on, read back the position in which they were sensed the last time a switching operation took place. Devices with sensing off simply read back the currently programmed state (which will be the state they were set to at power up if they haven’t been switched since power up). Devices with DRIVE:OFF read back the last value to which they were set.
