6.1 Select Frequency Sweep
Press
Sweep
at the front panel to enable the sweep function (the backlight of the key goes on),
and
Mod
or
Burst
function will be automatically disabled (if currently enabled).
To avoid multiple waveform changes, enable the sweep mode after configuring the other
parameters (as waveforms and amplitudes of fundamental waves).
Press
Sweep
button again to close sweep mode.
6.2 Start Frequency and Stop Frequency
Start frequency and stop frequency are the upper and lower limits of the frequency for frequency
sweep. The generator sweeps from the start frequency to the stop frequency and then returns
back to the start frequency.
Start Frequency < Stop Frequency: the generator sweeps from low frequency to high
frequency.
Start Frequency > Stop Frequency: the generator sweeps from high frequency to low
frequency.
Start Frequency = Stop Frequency: the generator outputs with a fixed frequency.
When frequency sweep is enabled, press
Start/Center
to highlight "
Start
". Use the numeric
keyboard or direction keys and knob to input the desired frequencies. By default, the start
frequency is 100Hz and the stop frequency is 1KHz. Different sweep waveform corresponds to
different start frequency and stop frequency range.
Sine: 1μHz to 160MHz
Square: 1μHz to 60MHz
Ramp: 1μHz to 5MHz
Pluse:
1μHz to 50MHz
Arb: 1μHz to 50MHz
6.3 Center Frequency and Frequency Span
You can also set the sweep frequency boundaries of the sweep using a center frequency and
frequency span.
Center Frequency = (|Start Fre Stop Frequency|) / 2
Frequency Span = Stop Frequency
– Start Frequency
When frequency sweep is enabled, press
Start/Center
to highlight "
Center
". Use the numeric
keyboard or direction keys and knob to enter the desired frequency values. By default, the center
frequency is 550Hz and the frequency span is 900Hz.
