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.
