High Dynamic Range Active Measurement Configuration
With a few jumper changes, you can configure the active measurement configuration for
higher dynamic range measurements. By swapping the front panel jumpers for one port,
signal flow through the corresponding coupler is reversed, increasing the test signal
sensitivity by 15 dB.
In the forward direction, as shown in Figure 5-5, the signal flow through the test port 2
coupler (A22) is reversed by arranging the front panel jumpers such that RCVR B IN
connects to CPLR THRU and CPLR ARM connects to SOURCE OUT.
Search for "Option 014" in the embedded help index in the analyzer for more information.
