DTF Testing
40
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 or Quick calibration is done, the instrument is now ready to make a DTF measurement in
VSWR or Return Loss. If you like to not only measure the DTF cable length but also get highly accurate
and reliable data, you need to perform a full O-S-L calibration.
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
If O-S-L or Quick calibration has been done at the end of the port extension
cable for DTF measurement, the length of the port extension cable is
compensated automatically and is not included in the distance to the point of
discontinuity.
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
lightning. Electric shock may cause malfunction of or damage to the instrument.
