external file to generate more complex waveforms. We'll use a
simple sine waveform for this example. From the Waves menu
select the Sine. Leave the parameters in the Sine dialog box as
is and press OK.
12. The last step is to download the modulating waveform to the
LW120. Press the download button to send the modulating
waveform to the instrument.
Figure 3-22. Using ArbExplorer to Generate Arbitrary Modulating
If you did not make any programming errors, the front panel outputs
will generate frequency modulated waveforms having carrier
frequency of 2 MHz, deviation frequency of 100 KHz and
modulating frequency of 100 Hz.
We'll now check the results at the rear-panel sine output connector
and compare what we get there to what we see on the front panel.
Remove the cable from the main output connector and connect to
the rear-panel SINE OUT connector. Here is what you should
expect to see when you check this output:
1. Carrier is sine waveform with fixed amplitude level of 1V
into 50Ω.
2. Carrier frequency is 64 MHz
3. Deviation range is 3.2 MHz above and below the carrier
