2.4.1.1
The Real-time numeric values are displayed at the bottom of the Strip Chart window.
These values show the results of the conversion as it is transmitted from the ADC
(Figure 2-6). The value is displayed in Volts, Decimal, Hex and Binary formats. The
display updates each time a conversion is completed.
FIGURE 2-6:
A second set of values provides the ability to observe the effects of averaging
(Figure 2-7). When Averaging is selected, the Rolling Average mode is enabled. The
display is updated after every conversion based on the average of the last n
conversions where n = counts.
To enable averaging for each conversion, click the Enable Averaging check box. Use
the Counts drop-down menu to control the counts.
FIGURE 2-7:
To change the volts per division in the Strip Chart window, use the Volts per Division
drop-down menu and select the volts (Figure 2-8).

2.4.2
Acquisition mode performs an ADC on the RC0/AN4 I/O port pin and temporarily stores
the data from each conversion in the serial EEPROMs on the Signal Analysis PICtail
Daughter Board. When all conversions are complete, the data is uploaded to the PC
for display and analysis. Display options for this mode are the Oscilloscope, Histogram
and FFT.
