Electrical Sampling Modules
1.
Refer to the following
fi
gure as you perform the following steps:
a.
Connect the output of a +12 V power supply to the dual-banana plug
end of the OLM DC power cable.
b.
Connect the remaining end of the OLM DC power cable to the +12 V
input of the Re
fl
ectometer.
c.
Connect the RF output of the SNA to a Wave Guide-to-1.85 mm female
adapter. Connect a 50
Ω
, cable from the adapter to the RF input of the
Re
fl
ectometer.
d.
Connect the Re
fl
ection output of the Re
fl
ectometer to Input B of the SNA
through an Aritsu 560-10BX-2 cable.
e.
Connect the Ref output of the Re
fl
ectometer to External Level input of the
SNA the through a 50
Ω
, BNC cable.
f.
Connect one end of a Waveguide section to the DUT port of the
Re
fl
ectometer.
g.
Connect the Waveguide short directly to the remaining end of the
Waveguide.
2.
Set the SNA as follows:
Output level:
+9 dBm
Frequency Multiplier:
4
Frequency Span:
50 GHz to 65 GHz
No. of Averages:
8
Leveling:
External
Channel 1:
Off
Channel 2:
Input B
Channel 2 Meas/ Mode:
Return Loss
3.
Push the Calibration key to start calibrating the SNA to the Re
fl
ectometer.
4.
Follow the instructions on the SNA screen to complete the calibration,
with the following exception: leave the Waveguide short connected to the
Waveguide section throughout calibration. Ignore the instruction on screen to
connect a Waveguide open.
5.
Save the Cal/Setup in Memory Location 2.
6.
Leave the test equipment hooked up for use in later steps. You will use it
when you do the steps under
Measure the Power In.
