This is pUTracer, a perl based CLI for Ronald Dekker's uTracer3; a PIC16F based vacuum tube curve tracer. Read more about it at http://dos4ever.com/uTracer3/uTracer3.html

Design goal in mind: automation. I have a bunch of vacuum tubes that I need to test, and ultimately sell to folks who need them.

• tracer.pl is the brains that talks to the uTracer3 over a serial port.
• run_test.sh three tests, a test for producing a transconductance test, a plate resistance test, and a quick test at a default bias point.

For graphing:

• common.gnu is a common script used by the following gnuplot scripts
• plate_resistance.gnu does smoothed graphs of the plate current, and plate resistance.
• transconductance.gnu does smoothed graphs of the plate current, and transconductance.

Generate graphs with gnuplot (default output format is SVG, Scalable Vector Graphic): gnuplot -c plate_resistance.gnu tube-rp.csv or gnuplot -c transconductance.gnu tube-gm.csv

This software is under active development, and currently is lacking documentation and usage instructions. Check back later for progress.
