The analyzer provides the GPS time base
calibration function (Option GPS is required).
Locate the analyzer on an open ground to receive
the GPS signal from satelites. Then press
[System] >
{More} > {Service} > {Calibration} > {Time Base by GPS}
to
perfrom a GPS time base calibration.
Amplitude Calibration
The analyzer privides the internal amplitude
calibration function. Please refer to the procedures
below to perform an amplitude calibration:
1
Press
[System] > {More} > {Service} > {Calibration} >
{Amplitude calibration} > {Calibration}
2
Connect a 50 MHz CW signal to RF IN connector.
The allowed amplitude range is from –2 dBm to
2 dBm. Then press
[Enter]
to continue.
3
Input the amplitude number of the 50 MHz
signal in the pop- up window and press
[Enter]
as
a terminator.
The analyzer will perform a calibration according
to the input amplitude value. Press
{Clear data}
to
set to the factory- preset status with default
amplitude calibration data. The amplitude
calibration function is only available with the
firmware revision A.02.08 or later.
NOTE
Time base calibration takes only a short time when the inner
temperature is stable. When the inner temperature is
increasing, calibration takes a long period of time or will fail. If
the input reference signal is abnormal, the calibration cycle
will take a long and unpredictable time to exit, and the LCD
displays an error message.
