Operating modes

Triggered Burst

Each active edge of the trigger signal will produce one burst of the waveform.
Carrier waveforms:
Maximum carrier frequency:
Number of cycles:
Trigger repetition rate:
Trigger signal source:
Trigger start/stop phase:

Gated

Waveform runs while the gate signal is true and stops while false.
Carrier waveforms:
Maximum carrier frequency:
Trigger repetition rate:
Gate signal source:
Gate start/stop phase:

Sweep

Frequency sweep capability is provided for both standard and arbitrary waveforms.
Arbitrary waveforms are expanded or condensed to exactly 4096 points and DDS
techniques are used to perform the sweep.
Carrier waveforms:
Sweep mode:
Sweep direction:
Sweep range:
Sweep time:
Marker:
Sweep trigger source:
Sweep hold:
