AM:STATe {OFFON}

Carrier Waveform

The AM 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 waveform, select Arb at the top panel as shown in Figure 2- 2 and then select the desired

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