NC = "Normally closed" switch position
NO = "Normally open" switch position
C
= Common terminal of the SPDT relay
In this simple example, the two signal paths for the first and second test step are:
●
"Path_A"
(for the first part of the frequency range) =
Transducer 1
to
NC terminal
to
common terminal
to
test instrument
●
"Path_B"
(for the second part of the frequency range) =
Transducer 2
to
NO terminal
to
common terminal
to
test instrument

, the R&S
OSP supports
a wide range of switching applications.
The following basic step-by-step instruction demonstrates how to integrate a switch
unit in a typical application:
To configure a measurement:
1. Devise a test plan that specifies the signal paths for all test steps.
2. Evaluate the required switching actions.
3. Determine the required switch modules.
4. Consult with your sales representative for ordering.
5. Equip your switch unit with the required switch modules.
6. Define the relay states for each signal path.
7. Save all required combined relay states as path definitions.
8. Connect the switch unit to your test control system.
9. In your test control software (for example
path definitions in the specifications of test steps.
10. During tests, let your test control system consecutively activate the required signal
paths.
