My guess is that the clock source must be OK, otherwise the blinking function would not work or the display would blink at a "wrong" rate. I think I would probe all pins around both the LD110 and

Put a few layers of masking tape around the knurled nut closest the panel and apply clockwise torque gently with channel-lock pliers. If it doesn't come loose easily, put a wrench on the flats of the

Good point. I use a DC block permanently installed at the RF input of any DC-sensitive piece of test equipment. It only takes a couple of hundred millivolts of DC to trash the front end of an

Cheers Jim. Look forward to your findings. I've done similar things in the past, some even work with a Nano VNA, within reason... The secret I found in the immdiate past work life, is to

Hi guys, I'm having trouble removing this connector. I've slackened off collar 'B' anti-clockwise in the picture and it's free. Collar 'A' on the other hand, is immovable. It should slacken off and

Nice! That is a pleasant suprise. Would expect an EPROM change might have been required. I wonder if my Minolta has a similar upgrade. I will look in to it if I ever get the SCSI communication to

=== I don't have the schematic but I debugged a similar issue on a U1272A meter. On U1272A Aerr shows up if the meter is not in amps setting but leads are in amps connectors. The way meter figures out

Yeah, big myth there too. But that's ok. I don't have to bother with it; people who choose to can lay in the bed they've made. -Dave

I know, right? But there's no choice in the modern world with business. Even if there were, we couldn't use it, with the government CMMC requirements for data security ever-tightening on

Okay, well, I've been able to bring on the fault condition by simply rotating the datum dial whilst in the 'stop frequency' mode, so dirty keys are now looking increasingly unlikely (though they will

PM me direct for shipping info. Thanks, Alan

Yes, another scourge of nonsense and low tech form Apple. But you should be able to download a free viewer plugin for Windoze. My work laptop views them fine once I installed a

Does anyone have a schematic for a Keysight U1242B meter? I am trying to troubleshoot an "Aerr" error. Thanks. Mark

Good catch, Dave!? I'd kind of skimmed over the .pdf and then filed it for future reference myself. I'd measured some boards probably 10-15 years ago with a 50 ohm VNA and was surprised to get

Microsoft requires you to buy a plugin to easily view them. It’s an Apple format. The free ones are unwieldy to use. Peter

Hi Jurek, send your pictures in jpg format--> not in HEIC format nobody can read it. Peter ============================

Hello, For Joel: 1. Yes, the blinking +1 indication remains on DC. Actually, it remains +1 on any setting, with or without the converter inside. It does not seem to care. 2&3. I will report the
