Ah, very cool! Yes, I think an 8690 may be the most sensible option if you are shooting for bands above 18 or 26.5GHz and have the needed waveguide adapters already. I believe that the 8350 also has a 26.5-40GHz plugin called the 83572B (I looked at this for the full list of plugins), but I have...
Oh wow, that is a very nice set of plugins indeed! A 1GHz sampling oscilloscope is a superb piece of kit. Those external mixers for the 8555A are not easy to come by, either.
The 1416A is also a rather interesting plugin to me. Used in conjunction with a sweep oscillator like an 8690 and a...
Nice, sounds like you've got a pretty nice set. Out of curiosity, what specific plugins/modules do you have?
Yes, the 141A doesn't have the auxillary D-subs on the back. I don't know if you will be able to use a tracking generator or preselector with it in that case. I believe the 8444A...
Not at all. Most logic chips should have no trouble carrying data at several MHz, let alone in the hundreds of Hz. I'm guessing the limiting factor in this case will be the response of the photodiode.
Another option to consider might be to use an op-amp. This would allow for pretty high gain/sensitivity and give you greater flexibility around feedback and/or hysteresis ranges, or even be configured as a comparator depending on the kind of output you need.
My guess is that the edges are sharp enough that the vertical lines in between the top and bottom bars are just moving too fast to excite the phosphors on the screen. Are you able to see them, even dimly, if you turn up the bightness? Depending on the condition, you may also want to adjust the...
It is possibly an inductor, then, which would be consistent with you measuring it as a short. The 272 on the second line probably means it has a value of 2700nH, or 2.7uH.
Here a similar example of an inductor in a yellow package like that...
Welcome! I think you'll find this can be an excellent place to bounce ideas off like-minded individuals.
Does your handle suggest you dream of electric sheep? :p
Laser cutters are something I have had an interest in, but I would agree that currently there aren't a lot of good options at the hobby level.
Earlier this year I bought one of the generic "K40 machine" laser engravers, but I haven't had enough time to do as much with it yet compared to my 3D...
Yes, they're just ordinary labels stuck on. Modeling raised or indented text in Autodesk is absolutely possible, but sadly I don't have that function in HFSS as far as I know. At some point I may want to learn a proper CAD program, but for the purposes of making quick mock-ups for prototypes it...
I recently got myself a Tevo Tornado and I've been really loving it. While it doesn't have the extra fine 0.05mm resolution some smaller printers have, it has a good heated base as well as a very large 300x300x400mm print volume. Tevo printers also use special textured plastic sheets on their...
Just for reference, here is a simplified view of what is effectively going on, with the differential probes marking the differential output of the amplifier stage. As an additional note on the circuit above, D21 is a protection diode that prevents the voltage at TR4 from exceeding the maximum...
This circuit is a pretty classic differential long-tailed pair with a constant-current source. TR3, the non-inverting input, is biased to a constant 0V for a single-ended input with a differential output. The circuit with TR4 is set to draw a constant current of roughly 7mA through the MOSFET...
I guess whether or not something new will sound better depends on how good your current speakers are to begin with, but if your cabinets are starting to deteriorate to the point that they look bad then it mostly comes down to a cost-benefit of looks versus what you are willing to spend for...
