Waveform & Digital Pattern Output Window
The “A” series DaqTemp models
have a waveform mode for their
analog output channels. DaqView
allows the DACs to be configured in
interactive mode or waveform mode.
With “A” series DaqTemps, both the
Analog Waveform and Streaming
Output tabs are enabled.
• Selecting the Analog Waveform
tab accesses the standard analog
output window.
• Selecting the Streaming Output
tab accesses the arbitrary
waveform window.
Note: This window is not available
when the analog output window is
visible.
The following material identifies the
functions of various buttons and
regions of the window. Refer to the
screen shot at the right as needed.
Waveform and Digital Pattern Output Window –
Analog Waveform Tab Selected
In the Waveform Type box, you can select a standard function generator waveform (sine, square, triangle,
sawtooth) or a freehand drawing. In Freehand, move the mouse to the waveform window and draw a
waveform using the left mouse button.
The Save Waves button allows you to save the values of each displayed waveform to disk in an ASCII
format. The files created are compatible with spreadsheets and word processors, allowing you to
numerically inspect and/or alter the saved waveforms.
Sample Waveform File Format Examples
One Channel Two Channels
2043 2432293
1019 394345
300 29343456
923 743875 In the two-channel example (to the immediate
left), the entry preceding the is for
the first channel and the entry after the TAB is
for the second channel.
The Load Waves button reads any ASCII file of numbers up to the number of points specified in the
Updates per Channel field.
