5.Panel Operation
frequency for frequency sweep. The generator sweeps from the start
frequency to the stop frequency and then returns back to the start
frequency. Press the Start Freq/Centre Freq softkey to highlight Start
Freq, note that Stop Freq in Stop Freq/Freq Span is also highlighted,
input the desired frequencies.
You can also set the frequency boundaries of frequency sweep through
center frequency and frequency span.
Center Frequency = (Start Frequency + Stop Frequency) / 2
Frequency Span = Stop Frequency – Start Frequency
Press the Start Freq/ Centre Freq softkey to highlight Centre Freq, note
that Freq Span in Stop Freq/Freq Span is also highlighted, input the
desired frequencies.
For different instrument models and different waveforms, the setting
ranges of frequency are different. For detailed information, please refer to
Sweep characteristics in Specification on page 54.
(6) Press the source softkey to select the trigger source.
Internal means using the internal trigger source.
External means using the Mod/FSK/Trig Sync/Ext Mod/Trig/FSK
connector at the rear panel to input the external trigger signal. A sweep
will be generated once the connector gets a TTL pulse with specified
polarity.
Manual means using manual trigger. In sweep interface, each time you
press the knob under the current channel on the front panel, a sweep will
be generated.
Generate Burst (Burst)
Press the Mode key on the front panel, then press the Burst to generate
versatile waveforms in burst. Burst can last for certain times of waveform cycle
(N-Cycle Burst), or to be controlled by external gated signals (Gated Burst).
Burst can apply to Sine, Square, Ramp, Pulse and Arbitrary waveforms
(except DC).
