Tek is the only one that makes an "MDO" scope, it's pretty much a niche product in the mid range scope category.

Weeeell... It's not to be pedantic, but other MDO options are available in the market.

GW Instek makes a MDO-2000 series of scopes that addresses some of the issues discussed in this thread:

- High resolution 1Mpoint FFT with quick update rate.

- 40Msample memory.

- SA type UI where you don't have to adjust resolution etc. in the time domain.

- Nice broad selection of math functions on Ch1-4, Ref1-4: (the Teks limited math ability was mentioned earlier in this thread)

Measurement Pk-Pk,Max,Min,Amp,High,Low,Mean,CycleMean,RMS,CycleRMS,Area,CycleArea,

ROvShoot,FOvShoot,Freq,Period,Rise,Fall,PosWidth,NegWidth,Dutycycle,

FRR,FRF,FFR,FFF,LRR,LRF,LFR,LFF,Phase,RPRFShoot,FPREShoot,

+Pulses,-Pulses,+Edges,-Edges

Operators +,-,*,/,<,>,<=,>=,==,!=,||,&&,

Functions Intg,Diff,Log,Ln,Exp,Sqrt,Abs,Rad,Deg,Sin,Cos,Tan,Asin,Acos,Atan

The UI is pretty snappy to work with on my MDO-2004EX. I assume it's equally fast on the "high end" scopes, but I have no experience (I'm always on a budget). We've got Tek and Keysight at work and they are not faster to work with in the daily work. IMO they found a nice low cost way to make the scope fast by integrating both the processor and FPGA on a Xilinx single chip solution. It's both cheaper and faster to communicate on the same chip than going via the PCB.

It might be worth considering if your funds are limited and you have to maximize your value for money?
