Introduction to Programming
Switch and Attenuator Programming
This section covers programming of switches/attenuators (Table 1-2) from the
Web interface. The Web interface is used to demonstrate setting preset states
that are optimized for the switches supported by the distribution boards.

Agilent N1810/N1811/N1812 Series Switches
The Agilent N1810 / N1811 / N1812 series switches are supported on the
following distribution board:
• Y1150A
The bank diagram is shown in Figure 4-10 (the 34945A is in 34980A slot 1).
Presetting the Bank
In order to preset the banks on the 34945EXT module (the programming of any
switch or attenuator must begin with the preset state), '
ure 4-2) must be selected and the module's channel drive must be off (Config-
ure Module... button).
To set the preset values for the N181x series switches (Figure 4-10), select

equivalent to sending the SCPI commands shown, or to configuring the
switches to the settings indicated in the bank, module, and channel
configuration windows.
Changing Settings and Enabling the Channel Drive
Following the preset, use the bank configuration and channel configuration
windows (Figure 4-10) to change the preset settings as required. The SCPI
Command Interface window can also be used to send commands to the
instrument.
When complete, use the module configuration window to enable the channel
drive. (If using more than one 34945EXT, the channel drive source must be set
to EXTernal for all 34945EXT modules other than the master.) Use the bank
diagram to control (open/close) the switches (see "Y1150A Switch Control" in
Chapter 5 for more information).
Settings (commands) from any of these sources can be logged for transfer
to other programming environments (see "Logging SCPI Commands").
