Parameters
Name |
Type |
Comments |
nHandle |
SHORT |
Handle to a GX11X0 board. |
nChannel |
SHORT |
Specified
Channel number.
GX1120:
0
= GTWAVE_CHANNEL_A: Channel A.
GX1120:
0
= GTWAVE_CHANNEL_A: Channel A.
1 = GTWAVE_CHANNEL_B:
Channel B. |
pnWaveform |
PSHORT |
Standard waveforms can be one of the following:
0. GTWAVE_WAVEFORM_SINE:
Sinusoidal waveform.
1. GTWAVE_WAVEFORM_SQUARE:
Square waveform.
2. GTWAVE_WAVEFORM_TRIANGLE:
Triangular waveform.
3. GTWAVE_WAVEFORM_RAMP_UP:
Positive ramp waveform
4. GTWAVE_WAVEFORM_RAMP_DOWN:
Negative ramp waveform
5. GTWAVE_WAVEFORM_RAMP_DC:
Constant voltage
6. GTWAVE_WAVEFORM_NOISE:
White noise |
pnStatus |
PSHORT |
Returned status: 0 on success, negative
number on failure. |
Example
The following example loads a sinusoid waveform:
SHORT nWaveform;
GtWaveFuncGetWaveform (nHandle, GTWAVE_CHANNEL_A, &nWaveform,
