Operational Modes
Continuous: Output runs continuously
Triggered: Output is quiescent until triggered by
selected trigger source, then generates the number
of cycles set by the trigger count.
Gated: Output is quiescent until gate (trigger)
signal goes true. Output is continuous for duration
of gate signal.
Frequency Sweep: Standard functions and
arbitrary waveforms may be swept from 1 mHz to 20
MHz.
Trigger (Burst) Count:
For waveforms: 1 to 1,048,575
For sequences: 1 to 65,536
Note: Triggered and Gated limited to 10 MHz
waveform frequency. Sweep frequencies limited to
< 20 MHz.
