MEASUREMENT METHOD EXAMPLE
This chapter describes the operating method of the R3765/67G series.
All the screen displays used here are display sample of R3767CG.
5.1
Measurement of Transmission Characteristic (2 Trace Display)
5.1.1
Overlap Display Mode (Two Traces per Screen Measurement)
Here explains magnitude and phase measurement method using simultaneous display of 2 traces.
•
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.
Note:
OPT11 or OPT14 uses a different [MEAS] menu.
For more information, refer to the description on page 7-10.
Calibrate the frequency characteristic
Remove DUT and connect the through adapter instead.
Normalize in this state.
[CAL]
{NORMALIZE (THRU)}
Following the completion, return the connection to DUT (filter).
Change the scale of displayed trace
When the format is 2 trace simultaneous display like this, select which trace is to be
changed by “TRACE”.
Adjust the scale for the first trace (magnitude).
