Loss and Power Measurements
Set-‐Up for Loss and Power Measurements
To prepare the meter for loss and power measurements:
1.
Follow the “POWERING UP THE METER” sequence on page 15.
2.
Press the
!
or
"
key to select the required output port.
3.
Clean the output port on the front of the meter and the FC/APC
connector of the measurement jumper (see the “CLEANING THE
CONNECTOR ENDS” section on page 34).
4.
Connect the FC/APC end of the jumper to the output port on the
meter.
NOTE: Ensure that you are using the measurement jumper and not the
calibration jumper, which is labeled as such.
5.
Attach the appropriate detector adapter to the detector on the
front of the meter.
6.
Connect the output connector of the measurement jumper to the
detector adapter. This end of the measurement jumper is user-‐
selected and must be compatible with the input connector of the
DUT.
7.
Press the
λ
key to select the desired wavelength.
8.
Press the POWER key to set the meter to Power mode. When in
Power mode, the meter displays “Absolute Power” at the bottom of
the screen, in contrast, “Relative Power” is displayed during relative
power mode.
9.
Press REF key to take a reference. The display reads 0.00 dB. The
loss of the measurement jumper is subtracted from the DUT loss or
power measurement to be made (see Figure 9).
10.
Pressing and holding the REF key will take a reference at each
wavelength.
11.
Repeat steps 1-‐10 for the next required output port.
