MICSIG TO3004
Sealant SDS2104X
Rigol DHO924S
Pros/Cons from my point of view:
Micsig:
+ Portable
+ 1M/50 Ohms inputs
+ Hdmi output, high resolution screen (1280x800)
+ Active probe support (of course only micsig ones)
- No Eres
- Only 100k FFT
- A little bit meager trigger functions
- No bode plot function
- No inbuilt awg
Siglent:
+ 1M/50 ohms inputs
+ Low noise frontend
+ 2M FFT
+ Math functions incl. formular editor
+ Bode plot
+ Power Analyzer
+ Inbuilt 50Mhz awg
+ Matured software/UI, continous firmware updates
+ 10 bit mode (software)
+ Eres
+ Accurate timebase (1ppm)
+ Easy to hack with full options and 500Mhz bandwith (max 2ch)
- No video output
- No active probe support
- Math on 2ch max.
- No manual memory control ( for those who need it)
- Inbuilt awg got meager features
- Lower screen resolution (1024x600)
Rigol:
+ Small, lightweight, portable use possible
+ Native 12 bit resolution
+ Fresh, innovative UI
+ Low noise frontend
+ Hdmi output
- Rigol is known for it´s buggy software plus slow debugging time
- Only 7" screen
- Only 1M inputs
- No bode plot
- No inbuilt awg
- No autodetection probe capability
- Only vector mode (display)
If you don´t need a portable scope, no 12 bits and no video output, the siglent could be your choice.
At work we´re very confident with the siglent.
Otherwise try the micsig, the rigol I won´t recommend actually (plus it´s not launched yet)
