The specification of the probes (especially X10) should match the input capacitance of the scope. From that set of probes, select those that have a bandwidth spec at least what you would be looking at 95% of the time, but not more than the scope BW rating (to save $$).

The probe bandwidth needs to be equal to the scope's bandwidth. If you can find a probe that is recommended for the scope, then pick the same specs, you should be OK as long as the connector matches.

Some tektronix probes have an additional pin which carries a signal telling the scope that you have switched on a 10 x attenuator or have hit the ground reference or the identify button.

It's okay if the probe's bandwidth exceeds the scope's bandwidth, as long as the probe is comp'ed?

Yes, except that as the bandwidth increases, the maximum scope input capacitance it can compensate decreases. So a very high bandwidth probe, such as for a 2465, may not work on an older scope.

OK, this was not a problem when I was buying probes, but good to know. Thanks...

The above link is a very good source for probes.

Don't know what you are looking for or the price but this one shows to work and it is 4 channel.

  1. look at the sellers ratings
  2. read the feedback on the seller
  3. Pictures showing it working is a plus.
  4. If seller states it is in full working condition and they have a high approval rating...probably is..

Usually I've a tagline on munging the mail-to. But I just reloaded the newsreader.

That does look pretty good.

I also noticed some scopes by a company called "Kikusui" I believe... "5 channel 12 trace". Trying to find some reviews online for them now. The price is good enough to worry me...

I went ahead and purchased that one. Thanks for the heads-up on it.
