R3765/67G Series Network Analyzer Operation Manual
5.1 Measurement of Transmission Characteristic (2 Trace Display)
5-6
5.1.2
Split Display
Here explains how to measure logarithmic magnitude and phase with simultaneous display of
channel 1 and 2.
•
880MHz band-pass filter is used as DUT.
Setup (refer to sub-section 3.5.1) and preset (refer to sub-section 4.4.1).
The setting of the R3765/67G series is as follows.
Change the input port of channel 1.
Note:
OPT11 or OPT14 uses a different [MEAS] menu.
For more information, refer to the description on page 7-10.
Calibrate the frequency characteristic.
First, remove DUT and connect the through adapter instead.
Normalize in this state.
