DSO Touch Official Leak – Test
This is the final episode of DSO Touch Official Leak Series, cause I have to wait for the sample until mid Sep, the only 2pcs of DSO Touch are sending to Petteri Aimonen & Tobias Schramm.
The input signal for distortion test is sine wave, ranging from 10kHz to 20+ MHz. We judge the level of distortion by
- FREQ measured
- VPP measured
- Shape of wave
Let’s go.
Result – DSO Nano V3 with BenF firmware.
- 10 – 40kHz: everything seems ok
- 50kHz: the measure FREQ is 44.9 kHz (acceptable), a discontinuous pattern begins
- 60kHz: went wrong
Result – DSO Touch Beta v0.1
- begins @ 40kHz: everything seems ok until 100kHz
- 110kHz – 130kHz: a error in FREQ, but the wave on screen and VPP is right
- 160kHz+: went wrong
Result – DSO Quad
- begins @ 21kHz: everything too easy for it
- 100kHz – 800kHz: ok
- 3MHz+: the shape becomes unstable from this moment.
We can tell the difference from this simple test. DSO Touch is regarded as an updated DSO Nano. With much wanted improvements on performance, we hope a better updated firmware from community.
