Keysight 87104/87106/87406 - L7104/L7106/L7204/L7206 Switches
The Keysight 87104/87106/87406 series and L7104/L7106/L7204/L7206 series
switches are supported on the following distribution board:
- Y1151A
- 87xxx series and L7xxx series (two switches)
The bank diagram is shown in Figure 4-11.
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), ‘
Allow Full Control
’
(Figure 4-2) must be selected and the module’s channel drive must be off
(Configure Module... button).
To set the preset values for the 87xxx and L7xxx series switches (Figure 4-11),
select ‘
Preset Bank
’ in the Bank Configuration window. All switches supported 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 L4491A Option 002 is installed, the channel drive source must be set to
EXTernal for the second 34945EXT - remote module 2.) 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”).
