content: I have acquired a HP2465A with the little cash I managed to save up for the thing, but did not realise the unit would not come with any probes. Currently I am using some 2nd hand 60Mhz ancient no-name probes, but they are pretty much worn out, etc. Obviously the scope is capable of 350MHz, but the cost of such a probe is prohibative, and I do not think that at this point I need that kind of bandwidth, so anything 100MHz or better would be great.I am looking for anyone that may have some decent old probes laying around that they have replaced and would be willing to part with for cheap (<$50). Since this is my first scope, and my budget is very limited, any help in getting my hobby shop set-up would be greatly appreciated.

content: Get this set:http://uk.farnell.com/testec/tt-lf312-2-6-10020-2-6/probe-oscilloscope-double-low-freq/dp/4308098Or buy single ones with more accessories:http://uk.farnell.com/testec/lf312/probe-oscilloscope-low-frequency/dp/220619I use these myself and they are excellent for general purpose work. I'd strongly advise against getting used probes. Probes do wear and need replacing after a while. I guess the scope has a 50 OHm input setting. Get (or make) a passive divider probe for measuring signals over 100MHz. In practise most high frequency circuits don't like to be measured by a probe with a high input capacitance so the use of a high frequency probe is mostly theoretical.

content: +1 on the Testec 150 MHz probes from Farnell, I had a set on my last scope and rate them very highly for the price.It seems most second hand scopes come without probes, which is a great shame as they can be quite expensive. I agree that buying used can be a bit of a minefield, but it can work out. I bought a set of used genuine Tektronix P6139A 500 MHz probes from a guy in China for a fraction of the price of new ones, and they're perfectly good.

content: I'll have a look, I'm pretty sure I have a probe or two somewhere, maybe sill in the baggie. Not sure of bandwidth.Won't be an Agilent or Tek though.Send me your snail mail address and you'll get a care packageDave.

content: Tiny detail but important one, whats your scope's input capacitance ? This will help Dave to find the right one that has the adjustment range that fit at your scope's input.

content: Quote from: EEVblog on March 05, 2013, 10:26:19 pmJust like to publicly thank Dave as his care package arrived today which contained 2x TESTEC TT-MF 312-2-6 150MHz Oscilloscope Probes along with a few other things, thanks mate.Edit: Interestingly the probes paperwork states they are 250MHz with x10 attenuation, but the farnell site shows that they are 150MHz... this a Farrnell error?

content: Quote from: gnif on March 12, 2013, 10:06:25 amAccording to datasheet its 150MHz (15MHZ at x1) but datasheet could be out of date. Is the paperwork from manufacturer? Pricing is interesting too, one probe is $58, set of two $50.
