Frequency Sweep

Start Frequency and Stop Frequency
The start frequency and stop frequency set the upper and lower frequency
bounds for the sweep. The function generator begins at the start frequency,
sweeps to the stop frequency, and then resets back to the start frequency.
• Start and Stop frequencies: 1 mHz to 10 MHz (limited to 100 kHz for
ramp waveforms). The sweep is phase continuous over 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
<
stop frequency.
To sweep
down
in frequency, set the start frequency
>
stop frequency.
• For sweeps with Marker Off, the Sync signal is a square waveform
with a 50% duty cycle. The Sync signal is a TTL “high” at the
beginning of the sweep and goes “low” at the midpoint of the sweep.
The frequency of the sync waveform is equal to the specified sweep
time. The signal is output from the front-panel Sync connector.
• For sweeps with Marker On, the Sync signal is a TTL “high” at the
beginning of the sweep and goes “low” at the marker frequency.
The signal is output from the front-panel Sync connector.
• Front-Panel Operation: After enabling sweeps, press the
Start
or
Stop
softkey. Then use the knob or numeric keypad to enter the
desired frequency.
• Remote Interface Operation:
FREQuency:STARt {<

>|MINimum|MAXimum}
FREQuency:STOP {<
