Also make sure that the 2 boards, A2100 DVM analog board and A2000, DVM logic & readout board are only connected/touching where they should. There needs to be a small space (say 1mm or less) between

You don't want the scope attenuator to be the dummy load. You can make a simple pick-off tee with the main signal going straight through, with a high resistance tapped off, feeding a termination

About ten years ago I built a dummy?load out of some huge 850 ohm?power resistors I?picked up at a hamfest. I?mounted a pair of heavy copper wires like a pair of rails?and then soldered the

That is because most sellers think they are just wires and are scrapped.

I know what you mean. Those tiny connectors are a PITA. When I first got a 7D01, I searched a lot for the probes, and considered even hard wiring some kind of cables into the front-end to go to

My 7L13 display was cured by pulling and reseating the DIPs on the RO board. IC pins were visibly tarnished. Symptoms not as complete as yours, but AFAIR the display would intermittently 'freeze'

Ok, that's what I thought. What I'm really trying to do is like this: 100W transmitter into a dummy load, with a tee in that line going to the scope. Would 10x be enough? Or should I aim for

Hi I'm looking for a pair of P6451's for a LA501and WR501 to make it complete, but I agree 100 is way too much , I'd be a buyer at 50.00ea. Regards Dave?

Hi guys It was quite some time ago but I found a 25 way micro D plug so decided to have a go at building a probe to test out a rebuilt 7D01. It ended up as only 4 channels as I didn't have enough

Hi, I finished building the first prototype of my 7X03 extender/load plugin. I have verififed that its extender function works and am ready to try the min-load function. I have 2 working 7704As and

I've managed to gather a bunch of information of the net about the probes that can fit my logic analyzer. They have the following part number?010-6451-0x , where x can be any number. If someone has

Thanks Bruce. I'm not in much of a hurry to get a programmer, so I'm looking for a decent one that will fit my budget. I'll look for those too. Mark

I haven't followed this thread but noticed that you purchased new TD's and as David says, your adjustments seem to be (quite far) off. Did you purchase the right TD's? They're not all the same! Peak

I believe all can be repaired thus far. I see no PCB damage. I've purchased a handful of slightly under-rated fuses (20%). It was a matter of what was available more than anything. Still waiting

The usual way to build such a probe is simple and excellent for measuring very fast sub-nanosecond pulses. It consists of a length of 50 ohm coax that's terminated in 50 ohms at the scope, either with

The readout operates in parallel with the BCD output from U2015 (frequency counter and latch). I would start by tracing backward from there. One or both of the digital signals (E or F) from

Hi all, I have a 7L13 Spectrum Analyzer out in the field, it's not in front of me right now but I will pick it up later this week. I've seen the unit and the 'Center Frequency' LED read-out is

schematics and pictures pls. I could not find any line receivers that have ecl output, single ended input and trigger on selective voltage.
