Click the

Run

button ( ) to initiate waveform generation.

The FGEN SFP default settings instruct the signal generator to generate a continuous sine wave at a
frequency of 1 MHz, with a peak-to-peak amplitude of 1 V into a 50 Ω load, and no offset. The

FGEN

SFP Help

includes more information about the FGEN SFP.

Generating an Arbitrary Waveform

To generate an arbitrary waveform using the FGEN Soft Front Panel, complete the following steps:

Note

NI 5402/5404/5406 devices do not support arbitrary waveform generation.

1.

Launch the FGEN SFP from

Front Panel

.

2.

Verify that the device you installed appears on the FGEN SFP display. You can choose a different
signal generator by navigating to

Device Configuration

to launch the device configuration

dialog box and selecting a device from the

Device

list.

3.

(NI 5450/5451 only) Select a channel from the

Channel

list where you want the waveform

configured. When using the NI 5450/5451 to generate waveforms on multiple channels, perform
steps 4 through 8 to load a waveform on to each channel on which you want to generate.

4.

Click the

Single Arbitrary Waveform Mode

button (

) to configure your device for arbitrary

waveform generation.

5.

Click the

Download Waveform

button (

) to download a waveform to the device onboard

memory.

6.

Select

Load Waveform from disk

. The Select File dialog box opens and displays waveform

example files. You also can download a waveform by selecting

File

»

Load New Waveform

. For

the installation location of the example waveforms, refer to the

NI-FGEN Instrument Driver Readme

.

7.

Select a waveform such as

arbMode-sine.lvm

and click

OK

. The File Load dialog box

and Waveform Preview window launch. You can close or minimize the Waveform Preview window.

8.

In the File Load dialog box, select one of the following settings from the

Waveform

drop-down

listbox:

NI 5412—

sine, 16MHz@40MS/s

All other signal generators—

sine, 40MHz@100MS/s

The FGEN SFP default settings instruct the arbitrary waveform generator to generate a continuous sine
wave, with a peak-to-peak amplitude of 1 V into a 50 Ω load, and no offset. The

FGEN SFP Help

includes more information about the FGEN SFP.

Tip

You can use the NI Analog Waveform Editor to create arbitrary waveform files.

Generating Waveforms Programmatically

You can control your signal generator programmatically with an ADE using the supplied NI-FGEN
Interchangeable Virtual Instrument (IVI) driver. You also can run the NI-FGEN examples to demonstrate
the functionality of your device.
