It depends , the 46GHz option changed the input connector , the regular 5352 just as the 5351 used a 3.5mm male connector which will work to 40GHz with degraded specs which doesn’t matter for a

Hi Lothar, I was refereeing to Dave's question of upgrading a 40GHz 5352B to a 46GHz 5352B option 5. And this is according to the posts I linked only connector and cable change. But as also described

Actually not , there were also some component changes on the A12 board between the 51 and 52 Counters , you can look at the schematics of the board to figure it out Sent: Tuesday, May 24, 2022 1:46 AM

I’ve upgraded my 53181 with an eBay prescaler and oven timebase. I believe I got them from a fellow in Poland. No problems at all. For the timebase I calibrated it to a rubidium standard as

These are "waveguide flanges". Waveguide is a common, very efficient way to move microwave energy around. See the Wikipedia article about it for an introduction. The size of a waveguide, and thus the

I recently acquired an HP P532A frequency meter. I know it's a resonant cavity device that goes from 12.6 GHz to 18 GHz but I don't how or what to hookup to the two flanges to get it to work. I've

Same thing for me, the option 3GHz (from China) works fine with my 53132A. I’ve done sensitivity test when I bought it, and it was OK. Yves De : [email protected]

I had problems with over voltage. I got UK Power Networks to reduce the voltage. But speaking to their engineers, UK Power Networks aims to supply consumers 245-250 V in rural areas. They get far more

I think these "prefer" a sine wave but will accept either. ________________________________ Sent: Tuesday, May 24, 2022 10:34 AM To: [email protected]

Ok well that was embarrassing. I found out what was wrong with it purely by accident. Looks like CR9 was broken. I was inspecting the area around the high impedance after the 100K carbon comp input

Hi Mike, I'm a bit slow on responding.... Great that the manual was what you needed. Unfortunately I can't help you with the transistors, but hope you are able to source them. Good luck with the

Ok got a decent DMM at my disposal. Scope due to arrive tomorrow. I applied the following test cases: 1. From step 5-6. Short V/ohms and COM terminals, set DCV and 10m range. Unstable reading at

From the time-nuts side of things, the general consensus is that the mismatch between 50 and 75 ohms at the typical 5 or 10 MHz distribution frequency is a complete non-issue. Even more so when you

HP8350B module has DC-FM capability. With an external PLL with correct settings, it can be locked use the AUX YIG signal from the back. However make it work with 8510 require some additional works, a

Yes, current sense resistor is in spec. It’s not the current foldback that is tripping the supply as far as I can tell. It’s an over voltage on the linear supply input to the -40V rail.

Yes, my belief was that UK mains voltage had 220V as the lower side and could go to 240V or more as you say. I don’t think that is the circuit - I’m referring to the A7A1 PCB circuit with three

Hi Tony In the UK the actual mains voltage is NOT 230VAC, it is frequently nearer to, if not over 250 VAC. When the UK harmonised with the EU 230VAC we did not change our mains voltage, just the

Interesting.- thank you Mark. I don't mind DIY, if I had a schematic. I would appreciate a suggestion if we can convert it 50 ohm distribution. That's a resistor network at the end of the signal path

I found a very hiqh quality detailed breakdown video on YouTube.about *GE Interlogix? Kalatel?KTS-250-16* (my unit) https://youtu.be/PjFr5YfxfLE by W2AEW (2015)

Samudra, I did this with a KTS-250 (the smaller version, setup as 1 input x 8 outputs) and I changed everything to 50 Ohms... works great. Not sure you need to though. Have the schematic somewhere in
