Selecting an
Output Function
The 3152B has four basic output function types. Use the following
commands to select the waveform type:
func:mode fix
The 3152B outputs the standard
waveform currently selected by the
FUNC:SHAP command (default sine, 1
MHz, 5Vp-p).
func:mode user
The 3152B outputs the arbitrary waveform
currently selected by the TRAC:SEL
command (default trace is 1).
func:mode seq
Selects the Sequenced Waveform
function. Waveform segments must be
downloaded to the instrument before it
can sequenced generate waveforms. In
addition, the SEQ:DEF command must be
used to define the sequence.
When programming a waveform function, you must consider the run
mode, since combinations of waveform types that are legal in one
mode may not be legal in a different mode. For example, arbitrary
and sequenced waveforms that do not conflict in Continuous mode
may conflict in Burst mode.
Selecting a Run
Mode
The 3152B offers five run modes:
•
Continuous
•
Triggered
•
Re-triggered
•
Gated
•
Burst
In Continuous mode, the 3152B repeats the selected waveform
continuously. The other four modes are known as
interrupted
, that
is, the output does not generate waveforms until an event initiates a
single- or multiple-output cycle.
Interrupted modes require a single trigger or multiple triggers to
initiate output cycles. Trigger events come from various inputs, such
as VXIbus backplane trigger lines or the front-panel connector.
Information on selecting a run mode and trigger source is given in
