Frequency Sweep
In frequency sweep mode, the instrument moves from the start frequency to the stop frequency at a specified sweep
rate. You can sweep up or down in frequency, with either linear or logarithmic spacing. You can also configure the
instrument to output one sweep from start frequency to stop frequency by applying an external or manual trigger. The
instrument can sweep sine, square, pulse, ramp, triangle, or arbitrary waveforms (PRBS, noise and DC are not
allowed).
You can specify a hold time, during which the sweep remains at the stop frequency, and a return time, during which
the frequency changes linearly from the stop frequency to the start frequency.

To Select Sweep
The instrument will not allow sweep or list mode to be enabled at the same time that burst or any modulation mode is
enabled. When you enable sweep, the burst or modulation mode is turned off.
To avoid multiple waveform changes, enable the sweep mode after configuring the other parameters.

Start Frequency and Stop Frequency
The start frequency and stop frequency set the sweep's upper and lower frequency bounds. The sweep begins at the
start frequency, sweeps to the stop frequency, and then resets back to the start frequency.
Start and Stop frequencies: 1 µHz to 30 MHz (limited to 200 kHz for ramps). The sweep is phase continuous over
l
the full frequency range. The default start frequency is 100 Hz. The default stop frequency is 1 kHz.
To sweep up in frequency, set the start frequency less than the stop frequency. To sweep down in frequency, set
l
the opposite relationship.
Sync setting Normal: Sync pulse is high throughout the sweep.
l
Sync setting Carrier: Sync pulse has a 50% duty cycle for every waveform cycle.
l
Sync setting Marker: Sync pulse goes high at the beginning and goes low at the marker frequency.
