$295 4-ch 50mHz -OR- $220 2-ch 200mHz Digital Oscilloscope

MrCreosote:
Honestly, I'm down-sizing (need space) and want to get rid of my hulking Tek RM503, 465B, and a Leader scopes.

I rarely use scopes, but last time I was watching digital signal train an OBDII break out box.
Most likely use: 

* viewing audio amplifier output clipping
* UPS output waveform shape
* room acoustics, subwoofer placement using FFT on microphone
Will I use it for RF?  Probably not (I'm not about to learn radio at 72)
Will I use 4-ch?  Probably not, but I never had one either.

Frankly, a 2-ch 20mHz would probably do the job, but never had 4-ch so curious and 100mHz is just so common and probably not a bad idea for better rise time, square waves, and logic pulse trains.

Really torn between the $220 price vs 4-ch

NOTE:  The 4-ch 100mHz is $395 which is simply not worth it to me.   (I could keep the 465B since it's 100mHz but I'm just so tired of the huge CRT scopes although I absolutely love Tek stuff including the tube scopes.

ALSO:  the rule of Tech is DO NOT buy for future use because prices keep coming down.  If you buy something for use 5 years for now, 5 years from now you'll be able to buy something better for cheaper.

My lever of confusion and indecisiveness is great.

Which brands / models are you talking about?

coppercone2:
Sometimes I wish we lived in a slower world where a 200mHz oscilloscope is considered to be high speed.

All those photons are too short, I am tired of it.

If you meant 200MHz, the answer is oscillations. If you try to build your own amplifiers and stuff, or do switching supplies, you can see fast edge signals ring, even if their not radio frequency signals. Or amplifiers that hang up and oscillate in some high MHz region. Its the difference between seeing a bad loop or being confused.

MrCreosote:
I'm hooked on the Uni-T Ultra Phosphors which have a 3-view FFT window which includes Waterfall (and 56M deep memory)
Models are UPO1054 and UPO1102  (you can see how they matrix the model number:  UPOabbc   a= series, bb= mHz, c=# channels

A more appropriate question should maybe have been:  recommendation for a beginners 1st scope:

My usage is strictly diagnosis/repair - I don't built circuits.

My major activity was/is computer repairs: bad caps and PCB damage repair under stereo microscopes.  Mechanical repairs.  Finding microscopic solder cracks, etc.

I'm so old school I have Hexacon soldering stations including a Magnum and also the light pencil SMD iron.  I want to get a hot air rig and a lab power supply I can run regulated V or A.  This hobby has been on a back burner for many decades, but interest is recurring.  I'm 72 so don't have much capacity to learn a lot of new stuff.

For PSU, audio and general use we have analog scopes, TEK 2465/7/B in US and Hameg 203/204 in FR.

10-20 MHz and 2..4 ch is fine for 99% of work.

have paid $5..40 for the Hameg in France! Still work fine.

For digital scopes we use Yokogawa DL1740 and DL7440.

Just my experience

Jon
