I looked at that vertical amp board again and found that the cans are plugged into Berg sockets, and there is thermal grease underneath for better cooling. Also, I hadn't noticed before that two of

Because it is there, and affordable. There are those who are a whole lot worse in that regard. The ultimate reference is a hydrogen maser - and there are guys out there who have one (have a look

I am curious what you guys are doing that requires that sort of long-term precision?

Thanks to the efforts of more canadian Tek fans, the 7934 and all those 7S/7T plug-ins will be here in Kelowna (April 9th) for stuff day. In addition, Larry Correa said he can bring back items for

Does anyone know what the differences are for part number 378-0199-00 vs 378-0199-03? The manual I have shows -00 as the correct part number for a 2445 and am wondering if the -03 will also fit (as

I 'second' Nigel's comments. You can get a 'stand-alone' 10 MHz 'reference' such as an HP 10811 or any of the oscillators you and others have mentioned and could be left on permanently. However,

Unfortunately, it isn't. The correct knob does not have the black insert at the front. Instead, there's empty space in that area to allow the pull-out variable attenuation button with its white ring

I've got four 24xx scopes, and on three of them the optimum focus point is roughly in the middle of the focus knob's travel. One one of them (a 2465) the best focus is with the focus knob turned all

The inputs on your instruments are not picky about waveshape. The Rigols expect a signal level in the range of about 0dBm to 10dBm and the HP VNA supports a much wider input range. Your Rigol

With any crystal oscillator, no matter how good they might be, or how well calibrated to start with, if that's all you have there will always be the issue of not knowing how well it is calibrated

I agree but make it three switching approaches as I have thought of another outlined below. Linking the backup memory function to the calculator keyboard has a certain engineering elegance that

I'm pretty sure that these canned hybrids are always plugged into Berg sockets that sit nearly flush with the board surface. These are among the most reliable IC pin connector types I know of, despite

Other ways of skinning the cat is a 10MHz Rb oscillator. Main ones are Efratom and FEI. Lots from USA and China from decommissioned comms racks. Also lots of options - sine, square, ones that

The first thing I would try is knurling the outside of the metal insert and using epoxy or hobby grade cyanoacrylate glue to set it within the plastic. Ideally the fit should be an interference fit

I have always been reluctant to mess with the various hybrids for fear of damaging them but I took a closer look at U50 in my 7854 and confirmed your description of the construction and

: waded through all the results? Thanks! Nathan KK4REY ......... I'm actually that guy that stalks the Tektronix listings religiously. It came up in the "ending soonest" category. I hope it's the

It'll work fine with the thermoplastic 3D printing material. I have inserted nuts before to get a stronger thread, just used a soldering iron to heat them up. With something large and thin like a

That sure looks like it. How did you find it? Searched "Tektronix knob" and waded through all the results? Thanks! Nathan KK4REY Sent using CloudMagic
