Narrow Band/Wide Band Sweep Measurement
Here explains how to set different measurement conditions between channel 1 and 2.
•
880MHz band-pass filter is used as DUT.
Setup (filter connection) (refer to sub-section 3.5.1) and preset (refer to sub-section
4.4.1).
Set the measurement conditions of channel 1 and channel 2 independently.
[MEAS]
{COUPLED CH ON/OFF}
Set the measurement mode, the bandwidth and the format of channel 1.
[MEAS]
AG type
: {B/R}
BG type
: {TRANSMISSION}
CG type
: {S21 TRANS FWD}

Calibrate the frequency characteristic of channel 1.
Remove DUT and connect the through adapter instead.
Normalize in this state.
[CH 1]
[CAL]
{NORMALIZE (THRU)}
Note:
OPT11 or OPT14 uses a different [MEAS] menu.
For more information, refer to the description on page 7-10.
Calibrate the frequency characteristic of channel 2 in the same way.
[CH 2]
{NORMALIZE (THRU)}
Following the completion, return the connection to DUT (filter).
