PC repeatedly. This mode is very useful to Monitor signals while making connections. The speed
of the continuous run will vary depending on the PC hardware and the Model of DigiView. With the
DV3xxx series, you can adjust the buffer to its smallest setting ( 1%) to have a virtual "LIVE"
mode.
the buffer is full. If you do not want to wait for a long capture, you can select the "STOP" button to
force a transfer of the current data captured. If you are waiting on a Trigger condition that you
expected to occur, you can still select the "Continuous Run" button to view the current signal
activity.

currently being analyzed.
Note that the DigiView hardware is always capturing and storing data in a circular queue. While
you are looking at the last capture, the hardware is pre-filling the buffer up to the 1/2 full point
(DV1-100 only) or to the buffer size selected (all other models). When the buffer reaches the
pre-fill setting, the hardware continues capturing and storing data in a circular queue fashion so
that the most recent data is always available but the remaining buffer is still available.
When you click on 'Run', you are actually arming the trigger circuit. Upon trigger, the hardware
allows the buffer to continue past the pre-fill point and to continue filling up (post-fill). Once the
buffer is full, it is transferred to the PC. After the buffer is transferred (or you abort the capture),
the hardware immediately resets and begins pre-filling in preparation for the next capture.
