Using a Curve Tracer for Testing Vacuum Tubes
http://aeaaudio.com/matching-tubes-with-a-curve-tracer/
We currently use two curve tracers: 1. An “old school” Tektornics 576 manually operated tracer. It has been modified especially for audio tube curve tracing... 2. A “new-school” uTracer model 3+ fully computerized (software driven) tracer. It …

Connect the eTracer to an open COM port on your Windows machine and load the configuration file “12AX7” from the library of tube definitions. Next, following the tube configuration table in the main interface (see Figure 11 ), FIGURE 11. Quick Scan interface. use the short banana cables to make the following connections: Pin 1 - HV1 Pin 2 - NEGV

way to make a Vacuum Tube Curve Tracer (VTCT) is to combine a Semiconductor Curve Tracer (SCT) with an ordinary vacuum tube tester. This has many significant advantages over designing and building your own custom vacuum tube curve tracer: The pre-wired test sockets of a tube tester allow the greatest variety of tubes to be tested.
yet another ultra simple vacuum tube (valve) curve tracer …
https://eevblog.com/forum/projects/yet-another-ultra-simple-vacuum-tube-(valve)-curve-tracer-build/
One of the challenge with vacuum tube curve tracer is the need to sweep the anode (i.e. plate) of the vacuum tube with high voltage (400v and more). The Valvewizard simply rectify the AC voltage from a transformer and apply it directly to the valve. For Europe this is good enough. However, the US AC voltage is only 120v and definitely no good.
FUtracer - A Better Tube Curve Tracer
The FUtracer is a tube curve tracer designed to work with your computer. Now you can get consistent and repeatable results. The Tube Socket PCB The tube socket board is setup for you to test (from left to right): 12AX7 etc., EF800 etc., EF86, EL84, EL34 /6L6/6V6 etc. You can also create your own tube configuration if you prefer. External PSU PCB
The Valve Wizard
http://www.valvewizard.co.uk/curvetracer.html
To trace a curve we need to measure the anode current and anode (to cathode) voltage, and plot them using the X/Y oscilloscope function. The current is measured by adding a 'current sampling resistor' in series with the valve, and measuring the voltage across it. …
