Pulse Train (Option 320 - Requires: Option Unw) - Agilent Technologies X Series User Manual

Pulse Train (Option 320 – Requires: Option 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 X- Series signal generator Pulse modes—the Pulse Train 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

Free-Run continuously plays
the pulse train, ignoring all
triggers.
Triggered runs the pulse
train (after waiting the Pulse
Delay) each time an external
trigger is supplied to the
PULSE BNC, the Trigger
Immediately softkey is
pressed, or the Trigger SCPI
command is sent.
Gated runs the pulse train
while an external trigger is
supplied (level triggered) to
the PULSE BNC connector.
The state of the GATEd
trigger is detected only when
the playback is transitioning
to or in idle. This means that,
once started, playback is
always completed, even if
the GATE trigger changes to
the inactive state.
