8. Press the
Frequency/Amplitude
submenu key to set up the frequency parameters of the
waveform to be captured. The Freq/Amp menu opens. Set the frequency, span,
reference level and scale for the y-axis, and attenuation settings for the waveform
capture.
Capturing a Waveform
Press the
Start Capture
submenu key. If Capture Mode was set to
Single
, a single waveform
capture will be taken. If
Continuous
is selected, waveform capturing ends when the
Stop Capture
(initial state
Start Capture
) button is pressed. When
Stop Capture
is pressed,
the current capture cycle will be completed and then IQ capture will end. The captured
waveform is named and stored in the file location set by
File Name (Prefix)
and
Capture Location
.
Note
When setting the Span, set it slightly larger than the captured bandwidth. This
allows you to see what you are capturing within the display. A good value to start
with is 125% of the captured bandwidth. Setting the Span this way does not affect
the bandwidth of the captured signal.
