Harvey, try to "temper" the PLA. Use a reflow oven. If you want, you can send me some samples to HU and I will use my "Wassulmayer" oven. - - - - - With best regards Tam HANNA Enjoy electronics? Join

3D printer materials vary widely in strength. PLA is pretty generic, ABS is available, some other varieties are available as well as flexible filament. You'd need a heated bed printer for some of

Hi Do you have access to a signal generator >3GHz? It would help a lot, because that can help you to figure out where the problem is. So if low band is low and high band is ok, the failure is most

I don't know. I'm fairly sure the OEM part was plastic. The parts don't seem to be under much stress, and the stress is distributed along the length. I've never done 3D printing, but a few components

I never thought of that!? My 3456A from HP might just be a chick magnet!? I will bring it along to the beach next time. Bob

sorry, maybe I didn't understand correctly, is the problem solved? the sound file doesn't look ok to me. can you lock to an external reference?

Check your power supplies first. Dave Wise

oh, was it heating up? had you measured the bias voltage and DC current draw in that MMIC? that usually (not always as I learned recently in repairing a R&S SME) gives you enough clue about the state

Amir Haven't done much to day but I am starting to get obsessed again about the 100MHz level as when looking at the circuit third converter for the reason that might be 20dB down I realised that the

When working on RF circuits only a proper RF active probe such as 85024A (ideal) or 1152A or 54701A or etc....will work forget about passive probes unless accurate amplitude measurement is not your

Hi all, have here a hp8640B how was OK in Amplitude and Frequency but Phase Lock was not possible and?when I listen with a SSB RX to the unmodulated carrier it has had a bad sound. Unstable and rough

Well said, Bob! I tried my leads on my 3456A also. My screwdriver measures 3 milli-Ohms! Jeremy [email protected]> wrote:

I made my own Kelvin test leads from some of those Chinese clips.? The clips are poorly designed and don't grip securely.? I flowed a bit of solder over the ends of the tips and it's much better. It

I ordered two sets from the eBay supplier linked here. They just arrived (9 days after placing the order) and both work correctly. I am pleased. Jeremy

Hi will the 3D printed ones be strong enough

In need of a pair of these plastic strips called "zipper", which I realized (after the fact) are how the two cabinet halves are held together (!). Is 3D printing a possible way to make these up?

AmirI think you are correct about the 100Mhz. I have become obsessed with the level without a proper method of measuring it. All the 300Mhz stuff following is working so can't be much wrong with it.I

Hi Stan For the older equipment feet with a silver button there are 3 different types of feet The 432 has 2 feet one on the front and one on the rear both are the full width of the unit this unit is

The excellent condition 432A power meter I just got has that style I believe, and it actually still had the feet. This makes me even happier. Sean
