Replacing the connector in the UTG932E generator

[AlexRG]

Hello everyone. It hasn't been a year since I bought this chinese generator, and it started having problems with the connectors. i turn on the meander, it is there. However, the meander arbitrarily breaks into a sine. If you move the connector cable, the meander returns again. But not for long. I tried to crimp the connector a little with pliers, but this does not last long. I tried to buy new cables, because I thought that the problem was in them, but the problem is not in them. The problem is in the low-quality chinese connectors  . Either the mass or the central conductor is constantly lost. I am already tired of this and several chips have already burned out because of this.

In general, please recommend a company and a model of high-quality connectors.

BNC connectors were suspect on UTG932 unit. Inner plastic shafts with holes had uneven lengths (two longer, one shorter). Expected higher quality, at least to have similar dimensions. Changed to proper BNCs as suggested by mnementh

To increase BW to 60 MHz, EEPROM does not have to resoldered, only 2 wires are needed for SCL/SDA as suggested by Dandymon

Check links above, suitable connector is Amphenol 031-5486. You can also do 60MHz mod.

Check also your cables. I got some Chinese BNC cables with connectors literally falling apart, made out of some zinc alloy with bubbles inside. Mechanical tolerance was also horrible causing bad contact.

Unfortunately, I won't be able to buy these connectors. But I have these in stock: TE Connectivity 5227161-7 https://lcsc.com/product-detail/Coaxial-Connectors-RF_TE-Connectivity-5227161-7_C591726.html

What do you think about this company, are these connectors quality or not?
