and input the frequency value, and complete the center frequency setting by
pressing corresponding frequency unit on the touch screen.
3
Set Measurement Port
To make a reflection measurement on port 1, keep the instrument default settings.
For reflection measurement on port 2, please perform the following operations:
a)
Press
【
Measure
】
→ [Meas Port 1 2], switch [Meas Port 1 2] and change the default measurement
type from 1 port to 2 port.
For transmission measurement, when the excitation source port is port 1 or port 2, please use the same
operation method to switch.

Calibration
Before performing the vector voltage test, after completing the frequency setting and other measurement
settings, calibration must be performed to eliminate the systematic error of the microwave analyzer to
ensure the validity and correctness of the measurement results.
One port reflection error correction
Single port correction can be conducted on S11 or S22 measurement of the microwave analyzer. The
two processes are basically the same, the difference is that the selected parameters and ports.
a)
In vector voltage measurement mode, select the type of measurement you want to make:
To measure reflection at port 1 (forward, S11), keep the default instrument settings.
If user wants to make a reflection measurement on port 2 (reverse, S22), press
【
Measure
】
→ [Meas
Port 1 2] , switch to [Meas Port 1 2] , switch port 1 to port 2, and measure parameters automatically
switch from S11 to S22.
b)
Set other parameters for measurement: center frequency, measurement type is the default
reflection measurement etc.
c)
Open the calibration menu, and press
【
Calibrate
】
.
d)
Press
【
Calibrate
】
→ [Cal Kit] to see if the calibration kit is consistent with the kit specified under
the current softkey. If not, press the corresponding softkey to select the correct calibration kit model.
Press [Back] to return to
【
Calibrate
】
menu bar, press [M Cal >] and select the type to be
corrected.
If user wants to make a reflection measurement on port 1, press [S11 One Port].
If user wants to make a reflection measurement on port 2, press [S22 One Port].
e)
If it is on the port 1, the system will automatically prompt user to connect the open device to the port
1, and then press the corresponding menu button to start the measurement! At this time, connect
the standard connector of the open-circuit device to the port to be used as the test port (P1 for S11,
and P2 for S22).
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.
f)
After the display trace is stable, to measure the normal part, press [OPEN] and analyzer will display
“Cal std measuring……” during the measurement of the normal kit. After the measurement is
completed and the error coefficient is calculated, it will display the prompt of ”Connect Short in P1,
then press corresp. menu button to start!” At this time, underline of the menu indicates the item is
tested completely, for example, [OPEN].
g)
Disconnect the open device and connect the short device to the test port.
h)
When the trace to be displayed is stable, to measure the normal kit, press [Short-circuit Device], the
microwave analyzer will display “Measuring……” during the measurement of the normal part. After
