Internal
This mode is the simplest acquisition mode, and is most useful when
used without buffering. Data is sent to the host at the maximum rate
that the communications channel allows. The F3200E runs indefinitely
after it is initiated.
External Start
The acquisition starts after it is initiated and a trigger edge is detected at
the gate input
External Start/Stop
The acquisition starts after it is initiated and a trigger edge is detected at
the gate input. It stops when the opposite edge is detected.
External Start/Hold
The acquisition starts after it is initiated and a trigger edge is detected at
the gate input. A single measurement is made on each trigger edge.
External Windowed
The acquisition starts after it is initiated and a trigger edge (rising for
example) is detected at the gate input. The acquisition pauses on the
falling edge, resumes on the rising edge and so on.
Sweep
The acquisition starts after it is initiated and a trigger edge (rising for
example) is detected at the gate input. Sweep Length number of
samples are buffered. This is repeated for each subsequent rising edge
and the data is averaged with the previous until Sweep Averaging
number of sweeps have been averaged. The averaged data is returned
to the PTC DiagnosticG2 program for display, and the process repeats
indefinitely.
Encoder Driven
This mode is not currently supported on the F3200E.
In Custom mode you must specify what starts, pauses and stops an acquisition. In other modes
you will need to set up some of the conditions.
11.8.1.2
Start On:
You can start the F3200E acquisition immediately when the Initiate message is received from the
host computer, or on the first gate edge after the Initiate. The required gate edge can be
configured to be rising or falling. The F3200E can look for the gate as a TTL signal on the Gate
In coaxial connector, or on the gate optical input. Note that the gate optical input is the same
connector that is used for fiber optic communications where the F3200E is the loop controller.
Loop controller function is unavailable if you use the input for triggering.
The start conditions are also the resume conditions if you set up pausing.
11.8.1.3
Pause On:
Pausing is optional. You can pause when a particular number of readings has been made (the
Burst Size). This is best used for buffered acquisitions, and in particular you can use it to get a
