Research study on Digital Delay/Pulse Generators

AI Thread Summary
Choosing a Digital Delay or Pulse Generator (DD/PG) primarily depends on its specific function and application. Users often recommend brands like HP/Agilent and Stanford Research Systems for their reliability and availability on platforms like eBay. Other brands such as BNC, Avtech, Quantum Composers, TTi, and Tektronix are also considered, but the decision often hinges on the user's needs and the specifications of each model. Many participants in the discussion emphasize the importance of long-term reliability and ease of comparison when selecting equipment. Ultimately, thorough research and understanding of personal requirements are crucial for making an informed choice.

Hello everyone,

I am doing a little bit of research on Digital Delay and Pulse Generators, and I would like to ask a question to anyone who works with that kind of equipment. How do you choose a DD/PG? The main criterion I guess should be it's function (DD/PG models are normally very specialized into a given application for its use), but I am looking for other choice criteria: are there more popular brands? More reliable models on a long term basis? What do you look for in a DD/PG?

Thank you in advance for your kind help.

P.S. I hope this is the right place to post this kind of question, if not please tell me and I will move it.

How accurate do you need to be? A counter and some and gates with switches
can get you a pretty digital delay.
When I need good equipment for my own use, I look on ebay.
some of it is a little older, but some of the old HP is built like a tank.
 
Well, I am not actually going to use one right now (in a couple of months probably), so for now I just want to know in general how you choose DD/PGs. Your answer was very interesting, thank you. I went to check ebay for the products they have, and I've noticed there are mostly HP/Agilent pulse generators and Stanford Research Systems (SRS) digital delay generators being sold there. What about other brands, do you consider them as possibilities when you want to buy a generator, or simply go for the most available product? I am thinking in particular of BNC, Avtech, Quantum Composers, TTi (Thurlby Thandar), Tektronix ... I mean there is a lot of choice. How do you make sure you will make the right one? Comparing the specs of every model is kind of laborious (talking from experience lol).
 
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
