Your concern is using up the useful life on the MCP or something else?  (I'm guessing Ground_Loop doesn't trace curves all day every day, and his MCP likely has it's timeout feature operating.)

The timeout is a convenience, but it won't protect the CRT from burns if you make a determined effort.

(MCP = microchannel plate image intensifier)

Curves are from a 6AU6 pentode.

I have been considering how to adapt tubes to my 575.  Thank you for this example!

The circuit is designed by Dennis Tillman. Attempting to attach PDF... nope, too big.
Instead search for "An Inexpensive Vacuum Tube Curve Tracer Adapter for All Tektronix Semiconductor Curve Tracers"

Here's the 575 testing the tunnel diode in the trigger of the 'b' timebase of a Tek 535A.

Vertical: 0.5 mA/div
Horiz: 50 mV/div

Vintage Tektronix, tunnel diode, beautiful photography... doesn’t get much better.

Super Cool!  :-+ :-+

I built one of the Thai Kits tracers, it works well.

I also have a Tek 577-177 that I have to repair one day (blown tants etc) and a 4145A that I have to track down a bunch of triax cables to connect it to the test fixture (and do the SD card floppy drive swap and maybe a colour LCD swap too if I feel like spending money).
