–
voltageRange—voltage range for the selected output channel
•
0: ± 10.0V
•
1: ± 1.00V
•
2: ± 100mV
•
3: OFF (not supported)
•
Set Hardware Update Rate
Default Value: 51200.0 S/s; Valid Range: 1,250.0 to 51,200.0 S/s.
•
Configure source
signal on or off, and sets the desired output signal type. Valid source
signal types are Sine (dual tone), Chirp, Noise, and Arbitrary.
–
sourceOn—turns the output source signal on or off
•
0: off (default)
•
1: on
•
2: one-shot
–
type—sets the type of output signal to generate. The valid values
for type, and the function to use to further define the outputs as
follows:
•
0: Default. Sine (dual tone). Use
next.
•
1: Chirp. Use
•
2: Noise. Use
•
3: Arbitrary. Use
•
Configure Sine source
–
Freq 1: Frequency of the first tone
–
Amp 1: Amplitude of the first tone
–
Freq 2: Frequency of the second tone
–
Amp 2: Amplitude of the second tone
–
DC Offset: DC offset, in volts, of the dual-tone signal output
If the source type is noise, you can also use the Noise Type and
Band-Limited Noise parameters. Refer to the NI-DSA online help for
more information.
