WaveStation 3000 Function and Arbitrary Waveform Generator
Generating Sweep Waveforms
Sine, Square, Ramp, and Arb(itrary) waveforms may be swept using a Frequency function, which sweeps
either from an absolute start frequency to stop frequency or across a frequency span at a specified sweep
rate.
Pulse, Noise, and DC waveforms cannot be swept.
1.
Set up a basic wave
of type SIne, Square, Ramp, or Arb.
2. Before outputting, press the Front Panel
Sweep
function button.
3. Set the following sweep parameters:
l
Sweep Time
- sets the overall sweep rate.
l
StartFreq
and
StopFreq
- the specific frequencies where the sweep begins and ends. If you choose
to set StartFreq and StopFreq, you do not set MidFreq and FreqSpan.
l
MidFreq
and
FreqSpan
- the frequency that must remain at the center of the sweep, and the overall
span or range that it may deviate from the MidFreq in either a positive or negative direction.
l
Source
- choose
Internal
,
External
, or
Manual
to manually start and stop the sweep. If External is
selected, connect the sweep trigger source to the
Trig/Gate/Fsk/Burst
connector on the Back
Panel.
l
TrigOut
- choose
Off
or
Open
. Open sends a trigger pulse on the rising edge of the waveform;
connect from the
Trig/Gate/Fsk/Burst
connector on the Back Panel.
l
Linear
or
Log
- choose either Linear or Logarithmic spacing.
l
Direction
- choose to sweep in either an
Up
or
Down
direction.
4. When all sweep parameters are set, press the appropriate
Output
button to begin outputting the wave-
form.
