We like the Rigols.I recently acquired a Siglenthttps://www.amazon.com/gp/product/B06XZML6RD/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1and gave it to one of my engineers. I'll ask him how he likes it.It has an up-front DEFAULT button, which a digital scope needs to getyou out of nightmare states.

Other than the lack of software features, the 200mhz bw for 350

It sounds pretty good to me.

If you want to save the last penny, maybe. But you can get way better scope
for slightly more -- Rigol DHO800/DHO900. It is 12-bit, same 550uV/div, has
all standard serial protocols decoding, very light and compact, can work
from a battery with USB-C power connector, way better than that Siglent that
feels like relic next to those DHOs.

We use almost all Rigols at work. My slow bench scope is a 500 MHz
DS4034 (upgraded from 350 MHz)

and my fast scope is a Tek 11802 sampler.

I also have one, 11801C. Couple of SD-24s, SD-20, and SD-22 heads :)

At the original purchase price, adjusted for inflation, I must have
half a million dollars worth of sampling heads.

The color grading and jitter measurement is great on the 11801C, but
the old B+W screens photograph better.

I'll miss my 11802 when it eventually dies.

The TDR is great. I'm going to give my new kids a lecture on

It is apparently possible these days to get an EE degree and be

My idea of good conversation is a group of people playing with ideas
and inventing stuff together. "Egoless" is the word, as in "egoless
programming."

I don't think you can do that. Some people are too fragile.

Sloman A.W., Buggs P., Molloy J., and Stewart D. A
microcontroller-based driver to stabilise the temperature of an optical
stage to 1mK in the range 4C to 38C, using a Peltier heat pump and a
thermistor sensor Measurement Science and Technology, 7 1653-64 (1996)
You did one academic, unremarkable temperature controller, published
in a journal, and have cited it here maybe 50 times now. Do something
new.
Here's my millikelven temperature controller.
https://www.dropbox.com/scl/fi/emxfaurnyj35t0y84tvwl/Oven_Cables_pub.jpg?rlkey=jpcnmnt1pcooz9nj7d0j4rah0&raw=1That's a dual-stage Mach-Zender e/o modulartor whose extinction is
much better if the temperature is stable to milllikelvins. The big
hogged-aluminum box is heated by six mosfets on the bottom, and there
are four thermistors for feedback. It runs at 30C.
This is part of the modulation system for a big laser.
I really over-did it on the enclosure. It's a lot heavier than it
really needed to be.
