Signal Separation Group Operation
The signal separation group divides the source incident signal into a reference path and a
test path. Refer to
Figure 5-3 on page 5-15 .
• The reference signal are transmitted to the receiver group as the R1 and R2 inputs.
• The test signal is transmitted through—and reflected from—the device under test
(DUT) and then is transmitted to the receiver group as the A and B inputs.
• Control lines to this group are routed from the A16 test set motherboard.
In this section, the following assemblies are described:
• A19 Switch/Splitter/Leveler/Amplifier/Multiplier (SSLAM)
• A21 and A22 Test Port Couplers
• A25 and A26 60-dB Source Step Attenuators (Option 1E1)
• Front Panel Jumpers— Configurable Test Set (Option 014)
