WGxx Arbitrary Waveform Generator Front Panel Operation
If the SyncPos value exceeds 9999, a simplified display format (see third
memory cell of Fig.13) will be applied.
Mode of Sync-Signal
Trigger Mode
With this menu the behavior of the sync signal can be modified. There, the
modes ‘normal’ (rising edge?), ‘inverted’ (falling edge?) and ‘pulse’ are
available using buttons 1 to 3 . Pressing button 3 again results in
a reversion of the pulse polarity.

If arbitrary waveform generation mode is selected, in addition the position sync
signal can be modified using the rotary knob.

Fig.15: Menu sync modes (for arbitrary waveform generation)
This menu allows the selection of continuous (cont), manual (man) or external
(ext) triggering of the instrument.
Remark: This menu is not active for WG810 in case of sinusoidal, triangular or
square-wave mode (i.e., analog waveform generation?).

For operating mode ‘continuous’ the arbitrary wave shape is restarted
automatically if the last sampling instant of at full cycle is reached.
Using trigger mode ‘manual’ (or ‘single-shot’) the instrument generates a
single arbitrary waveform cycle if button 2 is pressed.
For mode ‘external’ a single cycle is triggered by a TTL signal fed to the
AM/FM input. In this case AM/FM modulation is not possible.
