Electrical Sampling Modules
Power-Meter/Power
Sensor Zero/Cal
Follow this procedure to zero and calibrate the Waveguide power sensor to the
Power meter:
1.
Connect the Waveguide power sensor to the Power Ref output of the Power
meter as shown in the following
fi
gure.
2.
Connect the attached cable end of the Waveguide power sensor to the channel
input of the Power meter as shown in the following
fi
gure.
3.
Zero and Cal the Power meter to the Waveguide power sensor.

Measure the Power In
Follow this procedure to measure the power in of each SNA reference signal
at each frequency.
1.
Refer to the above
fi
gure as you perform the following substeps:
a.
Start with the test setup as was left from step 6.
b.
Remove the Waveguide short from the Waveguide section.
c.
Connect the Waveguide power sensor directly to the Waveguide section.
d.
Connect the attached cable of the Waveguide power sensor to the
Ch B
input of the Power meter.
2.
On the SNA, recall the Setup/Cal from Memory Location 2.
3.
Set the SNA Frequency Span to
0 Hz
to set the SNA to single frequency mode.
4.
Perform the following substeps:
a.
Set the SNA signal frequency and the Power meter frequency to each of
the frequencies listed in the
Frequency
column of the table. (See Table 9.)
b.
In the Horz Setup dialog box, set the main instrument Horizontal Scale to
(
1/Frequency),
where Frequency is the RF signal frequency.
c.
Turn Trace Hold on the SNA to
On
