Any instrument or tool that you can use is not garbage. We would like to own prestigious brands like Agilent and Tektronix. The only benefit of a Tektronix is its life time warranty. Tektronix will replace your Tek brand digital oscilloscope at no costs to you, when it breaks from old age. I like the Rigol 1052E very much. I have tried the really nice wide 7 inches (77.8 cm) diagonal screen Atten ADS 1102 CAL, 100 MHz with 500 MSamples/s real time very much for $399.00 from a Hong Kong vendor on E Bay. The wide screen reminds me like Dave Jone's Agilent wide screen, but without the nicely written manuals and high prices. I am not working much for the duration of the great recession. American recovery collapsed this month and we are at second episode of the great recession, very hardships here. I already went through electronics school and geology earth science school, so a detailed Agilent manual is not necessary. That is why an open mind and lots of schooling are always encouraged. Your Atten ADS is good. I have not tried the Hantek portable DSO 1200, like a Fluke Scopemeter form factor.
