Internal – The modulating source will be generated internally using the
PWM Freq, Width Dev, and Shape as defined in the previous steps.
External – Use external modulating source. Users can connect an external
signal into the rear BNC terminal labeled Modulation In as the modulating
source. PWM Freq and Shape options will not be available.
WARNING: Do not connect more than ± 6 V into the rear terminal. This will damage the
instrument and void its warranty.
3.5 Configure Sweep Output
Note: Sweep function is available for sine, square, ramp, and arbitrary waveforms. It is
not available for pulse, noise, or DC waveforms.
Burst function cannot operate when in sweep mode.
Follow the steps below to setup a sweep output from the generator.
1. Configure your waveform with the desired frequency and amplitude, then press the
Sweep button.
2. There are many adjustable parameters to configure the sweep function: SwpTime,
StopFreq, FrqSpan, StartFreq, MidFreq, Source, Trig Out (internal source), Edge
(external source), Linear/Log, Direction, and Trig (manual source).
3. To set the sweep time/rate, select SwpTime from the menu and use the rotary knob
or the numeric keypad to enter the sweep time in seconds.
Sweep time is the number of seconds required to sweep from the start to stop
frequency. The generator will calculate the number of points required in the sweep
based on this time.
4. To set the stop frequency, select StopFreq from the menu and use the rotary knob
or the numeric keypad to enter the stop frequency in Hz.
