44. Try adjusting the Number of Averages control using the + and - buttons in the Averager

block. Note that as the Number of Averages parameter is increased, the spectrum traces react

more slowly and smoothly to the input signal. Return the Number of Averages setting to 8.

45. Click on the Run button in the Averager block until GREEN LED is no illuminated. You

should see the spectrum waveform stop updating.* Click on the Clear button in the Averager

block; both spectrum waveforms should now be cleared completely away. Restore the Run

button to the active state to allow the spectrum waveform to resume responding to the input

signal.

46. Click the mouse anywhere on the spectral waveforms to move the vertical red marker to that

point. A readout of frequency (Frequency:) and magnitude (Magnitude:) of Trace 1and Trace

2 will be indicated below the display grid. Use the text entry box by the “Frequency:” indicator

to more precisely control the marker.

*The spectral analysis freezes immediately; however, the display will briefly continue to update as remaining data

is read from the PCAP II Plus external processor.
