Dennis, I've not gone through that particular Tek XYZ book. I guess I should. Thanks for that as well. Thanks for reminding me of that. Duh. It seems I've misplaced some of my analog knowledge.

Bob, I think that makes sense. I hadn't thought about is as analytically as that, but I understand the reasoning. Thanks! Dave

Folks, Thanks for the information. Without going through the TDS 'scopes' specs, I was a little confused, but you've cleared that up. I've also done what I should have done in the first place, which

Dave, The key word is "USEFUL". The simple answer is that depends on what you mean by useful which, in turn, depends on what you intend to measure with your probe and scope. To find the overall

Dave, Basically there is no frequency dependency of a probe.? It will divide the input signal according to the resistors in it and the input impedance of the load. Having said that, and for the

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 Casey Quoting Dave Daniel

Dave, If I recall correctly, the 485 has a bandwidth of 250 MHz in 1M ohm mode (350MHz in 50 ohm mode), so the P6139A might provide 250Mhz response. However, the high frequency (over 100 MHz or so)

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). Dave

John, I understand that. Thanks. But does impedance mismatch explain the P6139A spec sheet? If I use the P6139A with an analog scope (say, a 485), will I see a BW of 100 MHz or 500 MHZ (limited to a

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

Are you near a university? Their stationery store should have them.

Close to a 7504 or 7704. Early prototype? ? Jim

My mistake: the other model was 152-0125-01 They are used in: RM546, RM547, R148, R544, R556, 1L40, 1S1, 11B1, 11B2, 11B2A, 147/R, 147A/R, 1470, 148, 148M, 149/R, 149A/R, 21A, 22A, 3B4, 3B5, 408,

There are these TD: 152-0125-00 and 152-0125-00 Price seems reasonable (25$ each) I've no affiliation with the seller.

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

Anyone know what a Tek type M01 'scope is? Ebay item #350714574978. Thanks, Dave

Keith, In addition to the numerous suggestions offered for packaging filler, I will add a tip that I found very effective. Quite often during shipping the knobs on a heavy scope become broken as the

Hi Albert, I have a couple of 7603 rectifiers laying around that have good unregulated outputs very similar to the 7704A unregulated voltages. I will not have a 7603 connected. The connection will be

To all Forum Members: Many forum members have expressed interest in the Pyramid Generator and, as promised in the eBay ad, I have sent out numerous copies of the manual. I have confidence in the
