    Need switching device that doesn't affect impedance measurement

    Thanks for the tip. I think what I'm looking at now is getting a relay board that I can easily control via a computer. Will still have to decide on the type of relays to use, but I don't know if latching vs. non-latching will be a big issue. As for completely removing the device, are you...

    Need switching device that doesn't affect impedance measurement

    The Impedance Analyzer we're using is the Agilent 4294A. The analyzer is going to go on a ship and measure the impedance of underwater transducers as we travel. The transducer cables are grounded to the ship's ground, and thus I don't believe we need to worry about RF noise.

    Need switching device that doesn't affect impedance measurement

    Thanks everyone for the input. @Jim Hardy, I should have mentioned that aside from the impedance analyzer, the other output of the relay will be an echosounder, so something that emits and much more powerful signal, ranging from about 100 to 2000 W. So the switch would have to accommodate that...

    Need switching device that doesn't affect impedance measurement

    Thanks! Good to be back! Wasn't even sure if I still had an account but voila, I sure did. The impedance analyzer has Low and High output ports, which I normally connect straight up to the two wires going into a transducer. So, I think to answer your question, the impedance analyzer isn't...

    Need switching device that doesn't affect impedance measurement

    Hi all, I have a number of underwater transducers that I want to measure the impedance of by using an impedance analyzer. I'd like to create an automated system that cycles the leads of the impedance analyzer to the various transducers, perhaps using something like a decoder or a number of...

    What Is the Probability of Rolling 9 Buncos in 30 Rounds?

    I'll try to make this short, but this thread deals with the dice game bunco. Briefly, in the game, there are many different rounds, and in each round, you are trying to roll a certain number with 3 dice. So if we are going for 2's, we roll 3 dice and get points for how many 2's show up...
