3-10 Pulse Modulation Tests
Pulse modulation tests are performed only if Option 26 or 37 is installed.
For the following test, refer to the test record table in
“Section 3-10 Pulse Modulation Tests”
.
The pulse modulation tests verify the operation of the pulse modulation circuits in the MG3702xA. Rise time,
fall time, overshoot, and power accuracy of the pulsed RF output are verified using a high speed digital
sampling oscilloscope. The external power accuracy is also verified to insure the operation of the external pulse
input. Pulse depth (on/off ratio) is measured using a Spectrum Analyzer.
Test Setup
1.
Connect the equipment shown in
, as follows:
2.
Using the 2.4 mm (f) to K (f) adapters, connect a 6 dB fixed attenuator to the oscilloscope's
Channel 1
and
Trigger
inputs.
3.
Connect a RF coaxial cable to the 6 dB attenuator at the oscilloscope's
Channel 1
input.
4.
Use a BNC to SMA adapter to connect a 50
BNC cable from the MG3702xA's
PULSE SYNC OUT
to the
6 dB attenuator at the oscilloscope's
Trigger
input.
5.
Set up the oscilloscope as follows:
a.
Press the
Default Setup
key.
b.
From the title bar, select:
Measure | Math | Function 1
c.
Set the operator to MAX and turn on the
Function 1
display.
d.
Select
Close
to close the open window.
e.
Select the
Trigger Level
button on the bottom of the display.
f.
Set the trigger level to 500 mV.
g.
Set the bandwidth to DC to 2.5 GHz.
h.
Select
rising edge triggering
(soft key appears as a rising edge square wave).
Note
Before performing this procedure ensure that all test equipment is calibrated. Refer to the
manufacturer’s test equipment manual.
