Introduction to Programming
Agilent 87104/87106/87406 - L7104/L7106/L7204/L7206 Switches
The Agilent 87104/87106/87406 series and L7104/L7106/L7204/L7206 series
switches are supported on the following distribution board:
• Y1151A
The bank diagram is shown in Figure 4-11. In this example, the 34945A is in
34980A slot 1.
Presetting the Bank
In order to preset any of the banks on the 34945EXT module (the programming
of any switch or attenuator must begin with the preset state), '
(Figure 4-2) must be selected and the module's channel drive must be off (Con-
figure Module... button).
To set the preset values for the 87xxx and L7xxx series switches (Figure 4-11),
select '
on this distribution board have the same preset settings. Presetting the bank is
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 4-11) 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 "Y1151A 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").
