GO/NG Measurement Using Limit Line Function
GO/NG of DUT can be judged by using the limit line function of the R3765/67G series.
Besides the judgement of magnitude, GO/NG of Smith chart and Polar coordinates display can be
judged.

The following shows an example of how the limit line of 880MHz band-pass filter is generated.
Setting procedure
Setup (filter connection) (refer to sub-section 3.5.1) and preset (refer to sub-section
4.4.1).
Press [CH 2] to set the active channel to 2.
Setup start-frequency and stop-frequency.

Calibrate the frequency characteristic.
Remove DUT and connect the through adapter instead.
Normalize in this state.
Following the completion of [CAL]
{NORMALIZE (THRU)}, return the connection
to DUT.
Set the measurement format to magnitude (log display).
The display on the screen is as follows.
