F7 - Mark Data Point (executed when key pressed)
This key is active only when data are being recorded. Pressing <F7> marks the current sample so
it can be easily located when the data are later analyzed. On the graphical plot, this mark is
shown as a colored vertical bar. Each time <F7> is pressed, the event counter (shown to the left
of the active key) is incremented by one (it starts at 0). If data are being recorded, the marked
data point can be easily located in the data by the value of the event counter recorded with each
sample (see Section 3). The event counter has a maximum value of 999 and will start over at 0 if
incremented beyond this value.
Note
: The event counter is incremented by 10 whenever data recording is stopped and started
(using the Ctrl+S and Ctrl+Q keys described below).
F9 - Reset Trace (key pressed)
This key resets the graphical plots. That is, the traces are erased and plotting proceeds from the
left side.
Space Bar - Pause Display (executed when space bar pressed)
Pressing the space bar will freeze the screen display. Pressing the space bar again will resume the
display update. After a pause, there may be a discontinuity in the traces because data collected
during the pause are lost for display. During a pause, the program is still collecting and recording
data (if enabled).
Status
This is not an active key, but an indicator of the current state of the ADV. If external synchroni-
zation has been enabled, and the ADV is waiting for the first sync pulse, it will show
WAITING
FOR SYNC
. If data collection has been started and recording has not been enabled, it will show
NOT RECORDING
. If data collection has been started, recording has been enabled, and data are
currently being written to the computer disk, it will show
RECORDING
.
If data collection has been started, recording has been enabled, but data are not currently being
written to the computer disk, it will show
NOT RECORDING
and will alternatively flash this por-
tion of the display. This can occur during burst sampling when recording is stopped between
bursts or during continuous sampling if recording has been turned off with the Ctrl+S key.
Ctrl+Q
This will start recording from within the data acquisition mode, and is most commonly used in
burst recording mode (see ¶2.3). It can also be used when continuous recording has been stopped
using Ctrl+S. Note
: When the Ctrl+Q key is used to start data collection, the event counter is in-
cremented by 10. The current value of the event counter is displayed next to
F7-Mark Point
.
Ctrl+S
This key stops data recording, but keeps the system in data acquisition mode. After pressing
Ctrl+S, the software will continue to display real-time velocity data, but data will not be written
to disk. See the description of continuous and burst recording modes (¶2.3) for more information.
Alt+F10 - Stop Program (Confirm Yes/No)
To stop data acquisition, press the Alt+F10. You will then be prompted to confirm your intention
to stop data collection. Data collection proceeds normally until the confirmation is given. Once
stopped, the program returns to the setup mode.
