GtWaveSetOffset

Supported By

GX110, GX1120

Applies To

Function Generator and Arbitrary Waveform Generator modes.

Purpose

Sets the output DC offset voltage.

Syntax

GtWaveSetOffset (nHandle, nChannel, dOffset, pnStatus)

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.
dOffset
DOUBLE
GX1120:
Output offset voltage ranges from -4.0V to +4.0V.
The output level may be programmed from 0.1V to 8V p-p into 50 Ohm (0.2V to 16V p-p into an open circuit).
GX1120:
Output offset voltage ranges from -5.0V to +5.0V.
The output level may be programmed from 0.01V to 10V p-p into 50 Ohm (0.2V to 20V p-p into an open circuit).
pnStatus
PSHORT
Returned status: 0 on success, negative number on failure.

Comments

Offset may be applied to the output to shift the signal either positive or negative. Offset and amplitude are inter-related, i.e. the maximum positive or negative peak voltage at any time cannot be more then +/- 4V (GX1120) and +/- 5V (GX1120).

Example

The following example sets the output offset voltage to +2.0V:

 

DOUBLE dOffset;

GtWaveSetOffset (nHandle, GTWAVE_CHANNEL_A, 2.0, &nStatus);
