NOTE:
Do not use the standard piece of the open-circuit device or short-circuit
device for transmission response correction.

Figure 4-4 Standard piece connection for transmission measurement response error correction
Response and isolation error correction for transmission measurement
a) Select the measurement type as required in the VNA mode:
To measure forward transmission (S21), press
【
Meas
】
→[S21].
To measure reverse transmission (S12), press
【
Meas
】
→[S12].
b) Set other parameters for device measurement, including the start frequency, stop frequency, output
power, sweep points or IF bandwidth.
c) Open the calibration menu, and press
【
Calibrate
】
.
d) Select the frequency response error correction function, press [M Cal>]→[Resp.& Iso S12]
or[Resp.& Iso S21] to pop up a prompt automatically “Connect Thru cable between P1 and P2,then
press corresp. menu button to start!”. Conduct cable connection at the point to measure the device
at this time.
NOTE:
All adapters and cables to be used for device measurement shall be
prepared, that is, to connect the standard device to the position for
measurement.
e) After the trace is stable, press [THRU] to prompt “Calibrating standard piece measurement...” during
standard piece measurement, and show underline (for example, [THRU]) indicating item test
completion after measurement and error factor calculation and prompt “Connect the load to P1 and
P2, then press corresp. menu button to start!”.
f) At this time, connect the impedance matching load to P1 and P2 of the microwave analyzer.
g) After the trace is stable, press [ISO] to prompt “Calibrating standard piece measurement...” during
standard piece measurement, and show underline (for example, [ISO]) indicating item test
completion after measurement and error factor calculation and prompt “Press [Done] to complete
the measurement!”. [Done] is displayed at the same time.
h) Press [Done], the system will calculate the isolation error factor, and analyzer displays the corrected
data record line, indicating such channel data has been activated.
i) That is to complete the response and isolation correction for transmission measurement. The DUT
can be connected and measured at this time.
