SOFTWARE OPERATION

When the software is launched, the panel opens, and the software
looks for hardware connected to the PC. The software detects
the generic attached to the PC and returns this in a user dialog box.
The user software panel then launches, as shown in Figure 16.

USER SOFTWARE PANEL DESCRIPTION

The user software panel, as shown in Figure 16, has the following
features:
1. File menu with a+ choice of the following:
a. Load Data: load previously captured data in tab
separated values (.tsv) format for analysis
b. Save Data as .tsv: Save captured data in .tsv format for
future analysis
c. Print Front Panel Picture: use to print the front panel
to default printer.
d. Save Picture: use to save the current screen capture
e. Exit

2. When hardware is connected to the USB port, the software
automatically detects which generic is connected and displays
in here. Without the hardware, the software can operate in
standalone mode for data analysis, and the part information
notes the part number pulled from the saved data file.
3. Sampling frequency (fig says Sampling Rate?). The default
sampling frequency matches the maximum sample rate of
the ADC connected to the board. Users can adjust the
sampling frequency; however, there are limitations around
the sample frequency, where unusable sample frequencies
are input, the software automatically adjusts the sample
frequency accordingly. Units can be entered, such as 10k
for 10,000 Hz. Because the maximum sample frequency
possible is device dependent, with some of the ADCs
capable of operating up to 250 kSPS, while others can run
to 1.3 MSPS, the software matches the particular ADC ability.
If the user enters a value larger than the ability of the existing
device, the software indicates this and reverts to the maximum
sample frequency.
