Making Time Domain Measurements
Transforming CW Time Measurements into the Frequency Domain
Figure 3-20 Range of a Forward Transform Measurement
To increase the frequency domain measurement range, increase the span. The maximum
range is inversely proportional to the sweep time, therefore it may be necessary to increase
the number of points or decrease the sweep time. Because increasing the number of points
increases the auto sweep time, the maximum range is 2 kHz on either side of the selected
CW time measurement center frequency (4 kHz total span). To display a total frequency
span of 4 kHz, enter the span as 4000 Hz.
