DaqTemp Applications

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<CR> 2432<TAB>293<CR>

1019<CR> 394<TAB>345<CR>

300<CR> 2934<TAB>3456<CR>

923<CR> 743<TAB>875 <CR>

In the two-channel example (to the immediate

left), the entry preceding the <TAB> 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.
