thanks for the answer, I performed the same test on Tekway/Hantek "Recorder" so let's compare to Siglent Record/Recorder
Max of framesTekway/Hantek - 1000
Siglent - 2500
Minimum intervalTekway/Hantek - 1ms (but it takes 11ms for 1ms frame)
Siglent - 1ms (but it takes 44ms for one 1ms frame)
i can't speak for Siglent, but on Tekway/Hantek when i set 90ms then the real interval is 100ms,
so in principle always +10ms independant on interval setting.
What memory length can be enabled for Record featureTekway/Hantek - 4000pts (with max 1000 frames), 40000pts (with max 500 frames)
Siglent - automatic only screen size (~500pts)
Zoom on playback framesTekway/Hantek - yes (vertical and horizontal)
Siglent - no
Measurment on playback framesTekway/Hantek - no
Siglent - no
Cursor measurment on playback framesTekway/Hantek - direct no, indirect via REF or SAVE/RELOAD waveform - yes
Siglent - yes
ExtrasTekway/Hantek
- frames can be saved/reloaded an single/selected/all frames,
- each frame can be set as REF,
- each frame can be exported as CSV (such CSV can be later imported as regular waveform, so all
DSO operations like on normally exported/imported waveform available)
- screenshot of each waveframe
- not only zoom but as well vert/horz. position of playback frames can be changed
- FFT (when 4k memory selected) possible on each playback waveframe (manual scroll with F3/V0
knob only through frames, no autoplayback).
- playback data can
not be streamed to PC
- no separate "no-gap" recorder (except direkt access via SDK to Screen buffer or FPGA FIFOs)
Siglent (some maybe missing, see below)
- only screen snapshot
- for long timebase "Recorder" can be used for no-gap recording/streaming to PC
- I have not tested some things what you list as Extras
