9.4.3. Connect the necessary accessories (connectors, adapters and cables) to the device ports
P1
and
P2
through which the device will connect to the test device. Thus, as a result of calibration, the cali-
bration plane is transferred from the device ports
P1
and
P2
to the ends of the connected accessories.
Connect the loads from the standard set of calibration measures in series to the cable or connector
connected to port
P1
(not included in the delivery package):
Idle and press the
Open
button on the device screen;
Short circuit and press
Short
button on the screen;
Matched load, and press the
Load
button.
If you are performing a full two-port calibration of the device, connect the cables connected to ports
P1
and
P2
via a jumper and press the
Through
button on the screen.
After calibration, the buttons on the screen will turn green. To delete a calibration, click the
Open
,
Short
,
Load
, or
Through
button again. Connect the appropriate calibration measure and calibrate the
device.
Back
button-exit to the main menu.
Figure 9.9 - Device calibration process
9.4.4. Calibration information will appear in the information bar on the screen:
Factory
– there is no custom calibration. The device is factory calibrated. Displayed on the
device screen in white.
SOL
/
SOL+T
– one-port / two-port calibration performed. Calibration and frequency range are
the same. In this mode, the measurement results are the most accurate. The type of calibra-
tion is displayed in white on the screen.
If during measurements the frequency range does not coincide with the range in which the calibra-
tion was performed, but the frequencies are within the calibration range, the device uses a mathemati-
cal method to calculate the calibrations based on interpolation. The measurement accuracy will be
lower and the calibration type will be displayed in
blue
.
If the frequency range is outside the calibration range, the device uses a mathematical method to
calculate calibrations based on extrapolation. The type of calibration will be displayed in
red
on the
screen. The measurement accuracy is the lowest.
