ASKey:STATe {0OFF1ON}

Carrier Waveform

The ASK carrier waveform consists of Sine, Square, Ramp, Triangle, or Arbitrary waveform. The default waveform is Sine wave. You cannot use Pulse or DC as the carrier waveform.

Soft Front Panel Operation

For Arbitrary waveforms, select Arb at the top panel as shown in Figure 2- 2 and select the desired waveform

from the drop down list as shown in Figure 2- 16.
