Hi,
I have a Tektronics TDA220 Oscilloscope, and it's ok, but it's about time, I bought an upgrade.
Are there any suggestions for a more up to date Oscilloscope please?
400mHz +. Mid range price.

I have a TDS 220 and I would not trade it in for anything else.
It has served me well and continues to fill all my needs.

I agree except for the part about all needs.

To the OP, we need a actual price range and exactly what capabilities you need and those you want.
For starters:
Is 400MHz a bottom line need or want?

Hi Mr C,
Mine works ok, but for some reason, I don't find it easy to use. It could be that even though I've used Oscilloscopes for years, this one seems difficult, or is it, that I can't remember the settings.
The screen could be brighter too.
I don't know if there are outlets, where they could be tried hands on.

Hi N,
>=400mHz
I just looked at some prices!! I see they go up to £1000s
Are there any suggestions for >=400mHz...........4x channels (if poss) although 2x Channel is fine. around £500.

Your price range is for a budget scope .
Something like this

Hi N,
I forgot to specify a memory, and I notice SDS1204X-E (200 MHz) Oscilloscope has memory, also it's a 200mHz type.
I
was under the impression that the TDA220 was a 400mHz type, but it's 100mHz, and this is normally fine for what I want.
This is a good suggestion, and I'll look closer at it.
Thanks.

I didn't really think you needed a 400Mhz scope.
One other scope to look at is the RIGOL DHO series. It's one of the newer generation of Android powered scopes that has modern touchscreen interface and USB device connectivity.
There are 'hacks' to upgrade the lower cost models to full capabilities.

Just an old school lamp cord to a light fixture. No need to move your butt to turn on/off the lights while working or sleeping in the chair.
You need a design for an Arduino-Bluetooth wireless AC controller? I know a place where you can find one (at Arduino AC Controller.com).

Arduino-Bluetooth wireless AC controller, that's archaic old school stuff for beginners.

I have a complete home automation system using Matter switches that's integrated into the solar design system I'm building but I grew up with pull string lights (single bare bulb and one socket per room) as a kid so it's sort of familiar when you've had a few drinks.

I have a central MQTT server that handles the system remote data nodes. Back to scopes. Decoding serial MQTT data.

Hi N,
I notice that the bright and shiney Rigol waveform, is not as nice as the Tektronics one, although it is sharper. Which do you prefer?

You never answer that question when it's a possibility of them listening. ;)

The DHO is the one I use most, mainly because of the large HDMI screen capability for the scope display.
Grand-daddy is on the left in case I do need 400 Mhz analog capability.

Hi N,
If they hear your answer they may address it?

I had a vintage Hameg scope, which I liked a lot, and was intuitive, and pretty fast, but the screen popped and someone bought it to repair.

I also worked where there was an old LCR meter, which had a 6inch diameter coiled resistor for setting. I used to wind coils for a wire following camera buggy, and this was brilliant with accuracy.
