Default Re: Tektronix 465B Scope - Some problems.

Tek didn't get the probe sensing thing entirely right. I use a 50:1 resistive probe which works on 50Ohm terminated inputs on some of their faster scopes. It has the coded resistor contact on it, but the scopes get the ratio wrong.

The 50 Ohm switched termination is one thing missing on the 465 family, that is there on the rival HP1740.
