4-26 Pulse Modulation Tests with the 86100C Oscilloscope
The pulse modulation tests verify the operation of the pulse modulation circuits in the MG362x1A. Rise time,
fall time, overshoot, and power accuracy of the pulsed RF output are verified using a high speed digital
sampling oscilloscope. Pulse depth (on/off ratio) is measured using a spectrum analyzer. This procedure uses
the Keysight 86100C oscilloscope with the 86118A sampling head.
Test Setup
Connect the equipment shown in
1.
Using the 2.4 mm (f) to K (f) adapters, connect a 6 dB fixed attenuator to the oscilloscope’s
Channel 1
Sampling Head
and
Trigger
inputs.
2.
Connect a RF coaxial cable to the 6 dB attenuator at the oscilloscope’s
Channel 1 Sampling Head
input.
3.
For models without internal pulse, use a BNC to SMA adapter to connect a 50
BNC cable from the
Function Generator’s
SYNC
to the 6 dB attenuator at the oscilloscope’s
Trigger
input.
4.
For models with internal pulse, use a BNC to SMA adapter to connect a 50
BNC cable from the
MG362x1A’s PULSE SYNC OUT to the 6 dB attenuator at the oscilloscope’s
Trigger
input.
Index
Description
1
Connect the PULSE SYNC OUT from the MG362x1A or the SYNC from the function generator as
appropriate.
2
The function generator is required only if the MG362x1A does not have Option 24 or Option 27.
3
Connect the attenuator as specified in the procedure.
