The setting up of the signals themselves is discussed in the relevant sections later in this
manual, e.g. trigger is covered in chapter 7, Triggered Burst and Gate and position
markers in chapter 9, Arbitrary Waveform Generation.
Pressing the SYNC OUT key calls the SYNC OUT set-up screen:
SYNC OUT is turned on and off by alternate presses of the output soft-key.
The selection of the signal to be output from the SYNC OUT socket is made using the
src (source) soft-key; repeated presses of src cycle the selection through all the
choices (waveform sync, position marker, etc.) listed above. Alternatively,
with the src selected (double-headed arrow) the rotary control or cursor keys can be
used to step backwards and forwards through the choices.
The source selection of the SYNC OUT waveform can be made automatic (auto) or
user-defined (manual) with alternate presses of the mode soft-key. In automatic mode
the SYNC OUT waveform most appropriate for the current main waveform is selected.
For example, waveform sync is automatically selected for all continuous standard
and arbitrary waveforms, but trigger is selected in trigger or gated waveform
modes. The automatic selection will be mentioned in each of the appropriate main
waveform mode sections and a full table is given in appendix C.
The automatic selection can still be changed manually by the src soft-key even when
auto mode has been selected but the selection will immediately revert to the automatic
choice as soon as any relevant parameter (e.g. main waveform frequency or amplitude) is
adjusted. You must select manual with the mode soft-key for a source other than
the automatic choice to remain set. The auto selection will generally set the most
frequently used signal, for example waveform sync for all continuous main
waveforms, but you will need to use manual for any special requirements, such as
position markers on arbitrary waveforms.
Produces a pulse coincident with the last cycle of the burst.
Produces a pulse coincident with the end of a waveform
sequence.
Selects the current trigger signal (internal, external,
adjacent channel or manual). Useful for synchronizing
burst or gated signals.
Outputs the sweep trigger signal.
Used to lock two or more generators. Produces a positive
edge at the 0 º phase point.
