Frequency Sweep

Start Frequency and Stop Frequency
The start frequency and stop frequency set the upper and lower frequency
bounds for the sweep. The waveform generator begins at the start
frequenc
y, sweeps to the stop frequency, and then resets back to the start
frequency.
• Start and Stop frequencies:
1
Hz to 30 MHz
(limited to 200 kHz for
ramps). 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 less than the stop
frequency.
To sweep
down
in frequency, set the start frequency
greater than the stop frequency.
• When the Sync setting is set to Normal,the sync pulse does high
during the whole sweep.
• When the Sync setting is set to Carrier, the sync pulse has a 50% duty
cycle for every waveform cycle.
• When the Sync setting is set to Marker, the sync pulse goes high at
the beginning and goes low at the marker frequency.
• Front-Panel Operation: After enabling sweeps, press the Start Freq
or Stop Freq softkey. Then use the knob or numeric keypad to enter
the desired frequency.
• Remote Interface Operation:
