Introduction to Programming Switch and Attenuator Programming
Keysight 87204 / 87206 Series and 87606 Switches
The Keysight 87204/87206 series and 87606 switches are supported on the
following distribution board:
- Y1152A
- 87204/87206 series and 87606 (one switch)
- N181x series (two switches)
The bank diagram applies to both types of switches. The diagram is shown in
Figure 4-12.
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 N181x series, the 872xx series, and 87606
switches (Figure 4-12), select ‘
Preset Bank
’ in the Bank Configuration window.
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 4-12) 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 “Y1152A 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”).
