Dave,
The P6139A is designed for 1Meg ohm inputs. The 7A19 and 7A29 have 50 ohm inputs.

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
