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.
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.
