Remotely Control Data Recording
The recording can be controlled remotely via an external device, such as a behavioral control system. The remote
signal can be sent to the NSP through the digital input or the serial input. The recording can be remotely started,
stopped, paused, or a new session can be started. To setup remote recording using individual digital bits do the
following:
1) Open Central.
2) Open the File Storage app.
3) Click on Remote Recording.
4) Choose the input type to be Digital Bit Input for any of the four remotely controllable tasks.
5) On the second column choose a bit to be used for this function.
6) On the third column choose high or low for activating this tasks.
For example, to setup remote recording so recording starts whenever digital bit 3 on the DB-37 is set to high set the
second column to D3 and set the third column to High for “Start Recording” task.
Visualize an Input Channel on the Digital Oscilloscope
The digital oscilloscope app enables you to visualize up to two channels at a very high resolution. Triggering can
also be setup for improved visualizing of the signal. To setup the oscilloscope do the following:
1) Open Central.
2) Click on Oscilloscope. The Oscilloscope app will open.
3) Enable Channel 1 and/or Channel 2.
4) Select the channels from the drop down menus.
5) Click on Settings to make sure a sampling rate is selected for the given channel. If <none> is selected for sampling rate
then a trace will not appear in Oscilloscope.
6) Set the amplitude of each trace by changing the slider bar for each channel. The upper slider modifies the range of
values and the lower slider selects a value within the selected range. The units are µV/Division.
7) Move the trace location up or down by dragging the small triangle on the left side of the trace.
8) Set the time resolution by changing the resolution slider bar. The upper slider modifies the range of values and the
lower slider selects a value within the selected range. The resolution can be as small as 0.1 milliseconds.
9) (Optional) A trigger can be set for the traces. Select a trigger type (Single, Normal or Auto).
a. Auto: The trace will display continuous signal until the trace crosses the trigger level. When the trace crosses
the trigger level, it will momentarily pause until either the trace crosses the trigger level again, or after a short
pause, will resume displaying the continuous signal.
b. Normal: The trace will freeze as soon as the trace crosses threshold until the trace crosses the trigger level
again in which case the screen will update with the new trace.
c. Single: A single trace is captured as soon as it crosses the trigger level. To capture another threshold-crossed
trace click on Single again.
d. Choose a channel source to the trigger.
e. You can set the trigger lever by either entering a voltage value in the field or by sliding the trigger up and
down manually using a mouse.
f. Assign a trigger delay. Note that at 0, the trigger will be placed at the very left edge of the screen and may not
be visible. Set a negative value to push the trigger point to the right.
