NOTE:
If you have set this
Bias Voltage
to
On
, the instrument
will
supply a DC bias of
set level (12
– 30 V) from the
SMA
port
to
an
external bias-tee device.
Performing calibration
Perform the mechanical or electronic O-S-L Calibration by tapping the
Cal
icon
in the right side bar. The
instrument displays on-screen instructions for you to follow through.
Making a measurement
Once the O-S-L calibration is done, the instrument is now ready to make a reflection measurement in
VSWR or Return Loss.
Procedure
1
Disconnect the calibration kit from the calibration point.
2
Connect an antenna or feed line to the calibration point, which is usually at the extension cable end if
used.
3
Your measurement result is displayed on the screen in real time.
CAUTION
Do not apply or connect power exc30 dBm to the
Reflection /
RF Out
port. When the input signal power is greater than +30 dBm, it may cause a
damage to the CAA module and instrument.
NOTE
Do not change the connected port extension cable or frequency settings, or it
may cause a measurement error.
WARNING
Do not attempt to connect the instrument to the antenna when there is a risk of
