Hello everyone, I've been carrying out expert assessments in the various fields of EMC for 40 years, and in the early years I was able to use a MONROE 175 electrostatic voltmeter to measure how

So I used cyanocrylateto glue them together. I stopped the fogging effect by putting the knob above a fan to constantly move air. This allows the cyanocrylate vapors to move away from the knob and not

Not having a problem at all I'm using comcast e-mail with MS Echo in WIN10. Receive all emails with posts and can answer in the post or as a new message in the web site. Jim O

A cheap $100 vna can help diagnose signal path issues. This shows what happens when a micro crack in a connector can do. /g/TekScopes/photo/284401/3583773

Yes, the 2712 is different from the 492 series. But it still has a 1st if via a YIG but now at a slightly higher 2110MHz, 100MHz master and the same 110 2nd if etc. It is a completely new physical

Need a new-ish computer? discountelectronics.com -- I have half a dozen from them. Year warranty on most. Take a look. My only financial interest is the money I save on not buying new computers at

Funny how upgrade usually means downgrade and yes my system does not flow as well as it did. This page came up at the top where I could not see a place to respond. Going back from a message on the

Hi Jon, The 2712 has been in dedicated power supply ripple QC duty. It is fed by a jig with 0.1 uF caps blocking the 14 V supply DC, so it only sees any RF on the SMPS supply rails. It is possible

I have never paid that much for a computer. You can buy a new computer, but I typically buy recent, used business computers for under$100 and get several years of life out of them. I prefer a used

Howard, was the input ever overloaded, the mixer is easy to burn out, and the symptoms are low sensitivity eg -24 db down. Did the issue develop after measurement of a TX , PA or generator capability

Hi Jaap, I'm back on the 2712 diagnosis... I tested all the relays in the RF Attenuator block...and they were good, but upon reassembly the issue still exists: it does indeed show input, but the

?ann lau., 11. maí 2024 kl. 13:26 skrifa?i david via groups.io <davide_us= [email protected]>: Once you get the attenuator out, it’s easy to get into it. You do need to desolder the connection

Stand Down. I found enough to proceed.

I use an old XP machine for email so as not to clutter up my main machine. But now I can no longer send replies via the groups.io page. When sending the message it no longer goes through and I only

Now that I think about removing the front panel, it comes off without removing the knobs. I had to remove the knobs to replace the BNC connector. Are the relay contacts hard to get at in the

So, the relay contacts are in the attenuator? I really don't want to remove the front panel if I can avoid it. Knobs are prone to breakage when removing them. But at least I'm sure that the relay

I got channel 2 to 50ohm by repeatedly switching between 1Meg and 50ohm, after several hundred times, but it is still intermittent. Believe the relay contacts are the issue. Where is that relay

Hey David, The 50 ohm terminator is on the ceramic hybrid in the attenuator. It might have been burned by applying too much power, but it's also possible that you have an oxidized relay contact.

Hey guys, I bought another 2465 for parts, only 100 bucks. Have two 2465's already but couldn't stop myself from buying it. Channel Two 50 ohm DC Input is not working correctly. Can hear relay click,

Hi Beros, Very useful idea and excellent work! Renaud
