SetAoSweep

Function

Set the sweep information.

Format

Ret = SetAoSweep (AoChannel, SweepType, SweepTimes, SweepStart, SweepStop, Arg1)

Parameters

AoChannel [ VB.NET : Short ] [ C++ : short ] [ C# : short ]

Specify the channel number.

SweepType [ VB.NET : Short ] [ C++ : short ] [ C# : short ]

Specify the sweep type.

・Sinewave

0	None
1	Frequency sweep
2	Amplitude sweep
3	DC offset sweep

・Square

0	None
1	Duty ratio sweep

・Other waveforms

None

SweepTimes [ VB.NET : Short ] [ C++ : short ] [ C# : short ]

Specify the times of frequency.

Please specify a value between 0 and 10.

SweepStart [ VB.NET : Single ] [ C++ : float ] [ C# : float ]

Specify the initial value of the sweep used for conversion.

SweepStop [ VB.NET : Single ] [ C++ : float ] [ C# : float ]

Specify the value at the end of the sweep used for conversion.

Arg1 [ VB.NET : Short ] [ C++ : short ] [ C# : short ]

Fixed to 0. (Reserved)

Return Value

Ret [ VB.NET : Integer ] [ C++ : long ] [ C# : int ]

Return Value	Description
0	Normal completed
10006	Cannot execute because the device is in operation.
22000	Number of channels is outside the settable range.
22008	Sweep type is outside the settable range.
22009	Sweep time is outside the settable range.
22010	The value before the sweep change is outside the settable range.
22011	The value after the sweep change is outside the settable range.

The others (See also: Error Code List)

Initial Value

Sweep Type : 0 (None)

Remarks

The basic waveform can be swept.

This can be used when the basic waveform is a sine wave or square wave.

For other waveform types, there will be no sweep.

You can select from 4 types for sine wave and 2 types for square wave.

If the device is in operation, this function cannot be performed.

Example

Condition: Waveform type sine

The sweep type of channel 0 is set to frequency sweep, from 5Hz to 0.5Hz in the time of one waveform.

VB.NET

Dim Ret As Long

Ret = c_fgen.SetAoSweep(0, 1, 1, 5, 0.5, 0)

C++

long Ret;

ICWaveformGeneratorPtr c_fgen;

Ret = c_fgen->SetAoSweep(0, 1, 1, 5, 0.5, 0);

int Ret;

Ret = c_fgen.SetAoSweep(0, 1, 1, 5, 0.5, 0);
