Hi David Fair comment, maybe you could make your own probes but I don't think you could build a 10 channel 1Meg 5pF FET probe for less than the $100 asking price. You need the 25 way micro D

The publication on scope probes mentioned earlier is good and I am working my way through it. I already had it in my document collection and it was on my reading list. If I ohm out a 10x 10Mohm probe

I have to disagree, the price of $100 per probe is not viable. The Tek 308 is a primitive 20MHz logic analyzer, it would make no sense at all to spend $200 to get it going. You could get a much better

These people seem to sell the ECI line, maybe they can help you? http://val-tec.tripod.com/

Hi http://www.ebay.com/itm/Tektronix-P6451-Data-Acquisition-Probe-Accessories-new-old-stock-/130818471576? Unused new old stock and comes with a full set of leads. Price might be more than you want to

Hi, Thanks to everybody that replied, and for the tips, had wondered about applying some oil but I am worried that in time it might get through to the pot track and damage it? I should say that the

Seems the sphere guys no longer have these probes, so I'm in the market for some P6451 probes, part number 010-6451-07 to be exact.

Thank you! At this point the voltages are not OK, so I'll start to study the circuit.

The 318 used a special version of the P6451 probe, with a right angle connector. I don't know if a standard P6451 can be made to work. You can make the probe circuit, but I don't think you can find

Please try asking walter2@.... He has a wharehouse of stuff to clear. In his latest update, he mentioned about Tek 308 and many pods and probes. Difficult to make your own; best to buy actual

After installing the socket, I did an ohmmeter test on all connections to the socket from other chips and they are all fine. By default (no voltage applied), the input selection relay selects GND, so

Hi, I've just acquired a Tektronix 318 logic?analyzer, but it came without the pods. It's a nice unit, and by the looks of it, it works, well it displays random logic levels on screen as no pods are

I'm partial to Advin myself. Alternatively, a decent used Data I/O programmer. Happy hunting. * REPLY SEPARATOR * for

When you removed the chip did any of the plated through holes loose the plating? I think the board is up to six layers. You may have lost an internal connection to the chip. Tom

Priya, Wow, I didn't know it was all channels! Check your trigger setting, try a single shot too. maybe your focus is so far out you can't see it. Look at it in the dark too. Check the rejection

The 24xx digital scopes lack any such limit because they make measurements in a completely different matter. What I wonder is why the 2247A series which *do* operate in a similar way do not have such
