Phidget-PCA-Test-Example

Basic PCA level automated test example using Phidgets to power cycle a circuit board, take voltage data, plot, and store data in a CSV.

Wiring Diagram

For the purposes of this example the PCA under test is just a power supply in order to accentuate the output waveform. For a practical application this would be tied to whatever output or test signal that you wish to measure.

BOM

• VINT Phidget HUB0001_0
• Votage Input Phidget VCP1000_0
• Relay Phidget REL2001_0
• Generic Power Supply

GUI

Basic form accepts:

• Serial Number: Tagged serial number for DUT that's tagged in output file names
• Start Up: Time in seconds data is collected prior to test (before power-up)
• Duration: Time in seconds data is collected during the test
• Shutdown: Time in seconds data is collected after test (after power-down)
• Trials: Number of iterations of test

Output Data Files

The output data files are named in the syntax "YYYY-MM-DD HH-MM-SS [Serial Number]". For example "2023-09-03 13-05-21 SN12345"

The output data plot would appear as follows if the the voltage input Phidget was connected to a 3.3V supply. Each trial is overlayed.

The output CSV file is in the format below.

Sample	Trial	Elapsed	Data
0	0	0	-0.0027
1	0	0.012917	-0.0027
