Craig,
The option is 122C and Tek calls it 'High Voltage Diode Check'. I do not
have that option on my 575 but I infer from manual that current capability
is less than 1 mA: manual recommends to set display current to 0.01mA/div
when using this option. If you really want to convert your 575, I have a
write up, but work appears quite messy. The major additions are a
transformer and sections to rotary switches and there are also some changes
to wiring.
Regards
Miroslav Pokorni

I'm coming in late, so pardon if I'm responding
to a non-issue. Someone doesn't recognize the 571.
That was Tek's first transistor curve tracer.
Looks similar to its predecessor the 570 tube
curve tracer.
I think you're thinking of the 575, David. I have one just behind me as I
type. They do Tunnel Diodes too (with care), and mine will in due course
do
tubes as well (via an add-on box fed from the 175 connector on the back
and
the tranny sockets on the front). The only limitation for tubes is the
200V
maximum collector (anode) sweep. Those lucky ones who have an option (I
think 21?) have a 400V sweep, and that would clearly be even more useful.
