NOTE: The channel number is not required because the cal factor frequencies
are rounded to the nearest 500 MHz.
Step 8.
With no power applied to the sensor, press the
AMPLITUDE
key then the
Zero
soft key to zero the sensor. Zeroing the sensor is recommended when making
power measurements below –20 dBm.
Using Attenuators
Step 9.
Press the
AMPLITUDE
key and select the
Offset dB
soft key.
Step 10.
Connect the attenuator between the DUT and the sensor.
Step 11.
Enter the offset value of the attenuator, or select the

key.
Step 13.
Press the
Running Averages
soft key and use the keypad to enter the number of
averages to use (up to 50).
Step 14.
Press the
Max Hold
soft key to display the maximum value. If Averaging is se-
lected, Max/Hold will display the maximum value of the non-averaged data.
Step 15.
Press the
RUN/HOLD
key to hold the display in the current condition.
Setting Limits
Step 16.
Press the
MEAS/DISP
key.
Step 17.
Press the

Step 18.
Press the
Lower Limit
soft key and enter the lower limit value in dBm or in
Watts.
Step 19.
Press the

soft key and enter the upper limit value in dBm or in
Watts.
Step 20.
Press the
Limit ON/OFF
soft key to turn on the limits. The number display will
turn green if the measurement is passing, or red if the measurement is failing.
The word
PASS
or

Press the
AMPLITUDE
key.
Step 22.
With the desired base power level input to the sensor, press the
Rel
soft key. The
message area will show
Relative On
and the power reading will show 0 dB and
100%. If measuring a 10 dBm signal with the
Rel
key selected, a drop to 7 dBm
will show –3dB and 50%.
Saving the Measurement
Step 23.
Press the
