Advanced Modes

Three advanced modes exist:

• Modulation: selects the modulation type: AM, FM, PM, FSK, PWM

• Sweep: for frequency sweeps

• Bursts: repeats selected waveform n times

A modulation input (for AM, FM, PM, FSK, PWM) for each channel is provided on the
back-panel. In the two channel instrument one channel can also modulate the other
channel.
