Modes of Operation
There are four components to the mode of operation:
• Coupling between channels
• Trigger mode
• Waveform type
• Advanced modes
Coupling between channel 1 and 2
The two channel version has two distinct modes of operation:
• Coupling off: The two channels operate independently. Frequency generation for both
channels is based on the same clock reference, but can be selected independently.
• Coupling on: The frequency, trigger mode, waveform type and advanced mode are
identical for both channels. The fix delay of channel 1 and channel 2 is the same.
Trigger modes
• Continuous: Continuous waveform, burst, sweep or modulation. The External In is not
used in continuous mode.
• Externally triggered: Each active transition at the External In (rising, falling or both)
generates a single waveform, burst or sweep.
• Externally gated: The active level (high or low) at the External In enables waveforms,
bursts or sweeps. The last waveform, burst or sweep is always completed.
• Internally triggered: The internal clock replaces the external trigger source. This can
be applied for waveform, burst, or sweep.
• Manual: This generates a single trigger. The source is either a button
on the front panel or a remote command.
Trigger rate: 1 µHz to 120 MHz (external or internal)
