For these commands, the 34945EXT address is in the form:
<slot #><34945EXT #><00>
where:
For example, for a 34945A installed in 34980A slot 1:
ROUT:RMOD:BANK:PRES 2,(@1200)
presets bank 2 on 34945EXT slave module number 2.
Relay/Channel Relationship
The Agilent switches and attenuators listed in Table 1-2 are latching relays.
Therefore, there is a relay coil for each switch or attenuator position. In the
factory default configuration (
distribution board channel is assigned to each relay coil. There are 16
channels per distribution board.
Channel Pairing
Channel numbers on the distribution boards are arranged to facilitate channel
pairing for dual-coil switches and attenuators. In paired configurations,
channels 01-08 are paired with 11-18 (bank 1), 21-28 with 31-38 (bank 2),
41-48 with 51-58 (bank 3), and 61-68 with 71-78 (bank 4). Paired channels are
controlled by a single command (e.g.
channel of the pair is specified. When a command (
the operation sends a drive pulse to either the first or second channel in the
pair - either opening or closing the channel.
For the channel pair 01/11, the following syntax:
ROUT:CLOS (@1101)
ROUT:OPEN (@1101)
22
slot # - is the 34980A slot where the 34945A is installed. This is a single digit
between 1 and 8.
34945EXT # - is the 34945EXT module. This is a single digit between 1 (the
master 34945EXT) and 8. 34945EXT modules are numbered according to
their position in the daisy-chain sequence relative to the master.
