Looking to buy new scope for audio: R&S vs Keysight entry models
salomonander:
Thanks, i thought so as well. The specs are insane. THD+N -130dB

Yes, I bought an AP2700 for $500 from a previous company I worked for. Sold it on ebay for $8k I think it was. Great bits of kit.

It depends on your intended use. Analysis is one thing, but you say you do repairs.
I have several older Tek analog scopes, which have great triggering features for small-signal analog work, especially. In contrast, I find the Siglent SDS1202X/E very frustrating to use. |O
Mentioned trigger features are all digital methods, and only 1 trigger input. If you have a sig gen for trigger, an attenuated output could work for probing.
The Siglent FFT is a great feature; wish mine produced Bode plots. It's sensitive enough to show MW RF signals across the band with nothing more than a short wire... (and averaging). But that's RF-speak.
Maybe other here can say how they approach audio repairs?π

for audio applications, a 16-bit PicoScope 4262 could also be of interest.

Yes I would also go for a 14 / 16 bit picoscope.
I use them from 2012 and also have a tektronix mso4104, 99 our of 100 I use the picoscope.
There is a bode plot using the SKD with a lot of community support https://www.picotech.com/support/viewtopic.php?t=14311

Fixing audio circuits I’d think any scope will do. All you want to do is follow a waveform in the circuit, no?
I don’t think a scope is any good for THD, and so on since they don’t have the resolution or dynamic range, measurements its <100kHz so maybe even a good (external) studio sound card for the distortion, noise etc? Or 2nd hand, e.g., Neutrik audio analyser gear, but they are probably too expensive.
Or am I completely out of the loop for audio?
