Pulse On/Off Ratio
The following procedure measures the pulse on/off ratio of the MG362x1A’s pulse modulated RF output.
Test Setup
Set up the equipment shown in
, as follows:
1.
Connect the MG362x1A’s rear panel 10 MHz REF IN to the spectrum analyzer's 10 MHz OUT
(Switched).
Test Procedure
Measure the pulse on/off ratio as follows:
1.
Set up the MG362x1A as follows:
a.
Reset the MG362x1A by pressing
SYSTEM
, then
Reset
.
After reset, the CW menu is displayed.
b.
Press
FREQUENCY
to open the current frequency parameter for editing.
c.
Set F1 to the first/next applicable frequency in the test record for the model being tested.
d.
Press
Level
to open the current power level parameter for editing and set L1 to the
maximum specified leveled output power level.
e.
Press
Modulation
, then
Pulse
to select the
External Pulse Status
menu.
f.
Press
Low RF On
and ensure that the pulse mode is turned off.
2.
Connect the MG362x1A
RF Output
to the spectrum analyzer’s
RF Input
.
Note
If a message similar to “System needs alignment” appears on the screen of the E4448A, perform a
system alignment by pressing System | Alignment | Align all now. This will take a few minutes to
complete.
