Histograms
Histograms give you an easy way to evaluate statistics associated
with waveforms. The low-cost demo board produces noise that
appears as thick traces for any oscilloscope that captures its signals.
Use a histogram to measure the amount of this noise.
Make connections and perform initial setup:
1 To power the demo board, connect a USB cable between it and the
Agilent Infiniium 9000 Series oscilloscope.
You can also apply power by connecting the oscilloscope’s MSO
cable to the demo board’s 40-pin connector.
2 Connect the scope channel 1 probe to demo board CH1 and GND.
3 Make sure all other probes are disconnected from the
oscilloscope.
4 Turn the SELECT switch to position 7 (RS-232).
5 Press [Default Setup].
6 Press [AutoScale].
7 Adjust the horizontal position to -300 ns.
8 Set the time base to 50 ns/div.
9 Adjust the channel 1 vertical scale to 500 mV/div.
Set up the histogram:
