Daves,
The TDS3012 is a 100MHz scope. The P6139A works fine with the TDS305x, which is a 500 MHz scope and uses the same hardware (bandwidth limit is in the firmware).

Dave,
Thanks.
That still doesn't answer my question.
Why the differing BW specs for different 'scopes? Is it the 'scope or the probe or the combination?
Cheers,
Dave

The probes you want for the 50 ohm input amplifiers are P6056 (10x) and P6057 (100x) or P6156(10x or 100x versions).

Subject: [TekScopes] Tek Probe Question
All,
I'd like to buy some used Tek probes for use with the higher bandwidth 7000 series plug-ins (I'm thinking 7A19, 7A29, 7B10, 7B92A). I am looking at a Tek P6139A and decided to download the spec sheet from Tektronix to see the particulars of this probe. It is a 500 MHz probe, but the datasheet calls out:
500 MHz (TDS3054) or TDS500 series
100 MHz (TDS3012)
Now, I understand about passive probe compensation and all that. What I don't understand is what the 'scope-dependent bandwidth spec means. will this type of probe be useful close to 500 MHz when used with the >= 600 MHz BW 700 vertical amplifiers (e.g., response close to 500 MHz), or is there some probe/'scope dependency of which I am not familiar? I have several P6106s which I am currently using.
Thanks.
Cheers,
Dave
