5.3 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}
[CENTER] [8] [8] [0] [MHz]
[SPAN] [1] [0] [0] [MHz]
[FORMAT] {LOG MAG}
Set the format and the bandwidth of channel 2.
[CH 2]
[CENTER] [8] [8] [0] [MHz]
[SPAN] [6] [0] [0] [MHz]
[FORMAT] {LOG MAG}
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).
