b) Response error correction of transmission measurement
1) In the VNA mode, select the desired type of measurement:
If transmission measurement is required in the positive direction (S21), press
【
Measure
】
→ [S21].
If transmission measurement is required in the reverse direction (S12), press
【
Measure
】
→ [S12].
2) Set other parameters of the equipment measurement: Start Freq, Stop Freq, Power,
Points or IF BW, etc..
3) Press [Cal] to open the calibration menu.
4)
Select the frequency response error correction function, Press [M Cal>] → [Freq
Resp>] → [THRU S12>] or [THRU S21>], and the system will automatically prompt
"Connect Thru cable between P1 and P2, then press corresp. menu button to start!"
Then connect N-type cable between ports 1 and 2.
All adapters or cables used in device measurement should be
included, i.e. connecting standard equipment to the location where
the DUT is to be connected.
5) After the display trace is stable, press [THRU], the analyzer will display "Cal std
measuring..." during the measurement of the standard piece, and after completing
the measurement and calculating the error coefficient, the measured item will be
underlined, e.g., [THRU], with the soft key [Done] displayed.
6) Press [Done] to complete the error correction of reflection measurement, which
allows for connection and measurement of the DUT.
Do not use open circuit device or short circuit device standard
pieces for transmission response correction.
