i.
Select the left module as the source.
j.
Select
Close
to close the open window.
k.
Turn off channel 1 on the oscilloscope by pressing the
1
key above the module (LED off).
Pulse Rise Time, Fall Time and Overshoot
The following procedure describes the measurement of rise time, fall time, and overshoot of the MG3702xA's
pulse modulated RF output.
Repeat the measurements of the pulse rise time, pulse fall time, and pulse overshoot based on the DUT
frequencies according to
“Section 3-10 Pulse Modulation Tests”
.
Pulse Rise Time
1.
Set up the MG3702xA as follows:
a.
Preset the instrument by pressing
Preset
. After preset, the CW menu is displayed.
b.
Turn RF output off.
c.
Press
Edit Frequency
to open the current frequency parameter for editing.
d.
Set F0 to the first/next applicable frequency in the test record.
e.
Press
Edit Level
to open the current power level parameter for editing.
f.
Set L0 to the maximum specified leveled output power level for the frequency and
instrument being tested (refer to
,
“MG3702xA Technical Data Sheet”
).
g.
Connect a fixed attenuator with the proper attenuation value (see
) to the
MG3702xA
RF Output
, then connect the RF coaxial cable from the
Channel 1
input of the
oscilloscope to the fixed attenuator.
h.
Turn
RF output
ON.
i.
Press
Modulation | Internal
to select the Internal Pulse Status menu.
j.
Press
PRI
and enter 4 µs.
k.
Press
W1
and enter 1 µs.
l.
Press
Enable
to On to turn the internal pulse mode on.
2.
Set up the oscilloscope as follows:
a.
Select the
Time/Delay
button on the bottom of the display.
b.
Set the scale to 10 ns/div and the delay to 4 µs. Select
Close
to close the window.
c.
Press the
Clear Display
key. Allow the oscilloscope to sample the signal and wait for a
clearly defined waveform to appear on the display.
d.
