132 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
Using Pulse Modulation (Option UNU or UNW or 320)
Pulse Train (Option 320 – Requires: Option UNU or UNW)
4. Set the pulse period to 100 microseconds: Press Pulse > Pulse Period > 100 > usec.
5. Set the pulse width to 24 microseconds: Press Pulse > Pulse Width > 24 > usec
6. Turn on both the pulse modulation and the RF output.
The PULSE annunciator displays and the RF output LED lights.
If the modulation does not seem to be working properly, refer to “No Modulation at the RF Output”
on page 318.
Pulse Train (Option 320 – Requires: Option UNU or UNW)
The Option 320 Pulse Train feature enables the specification of up to 2047 independent pulse cycles,
each of which has an “On Time”, during which the RF output is measurable at the RF output
connector, and an "Off Time", during which the RF output is attenuated. Each pulse cycle is similar
in function to other MXG Pulse modes—the new feature has up to 2047 cycles, instead of only a
maximum of two (with Doublets). There are also repeat counts available for each pulse. These
repetitions count against the total count of 2047 cycles.
The instrument can import pulse trains from a .csv (comma separated values) file or some other
common ASCII format. It can also export to ASCII/CSV files as well. Export allows specification of
the decimal separator and a column separator. The import allows specification of the decimal
separator (to allow for ","), but the column separator is auto- detected. Refer to “Pulse Train Menu
Softkeys” on page 133 and “Display Pulse Train Menu Softkeys” on page 134.
