10/Jun/2025 Roberto: about oversampling

Classic oversampling scope modes such as HIGH RES, ENVELOPE, SAMPLE etc. do not apply to this scope.
The MXR is designed for real-time, high-resolution acquisition, using 12-bit ADCs and deep memory.
Instead use these settings:

| Traditional Mode | MXR Equivalent                        |
| ---------------- | ------------------------------------- |
| Sample           | Default real-time mode                |
| Peak Detect      | High sample rate + persistence + zoom |
| Envelope         | Display persistence + waveform math   |
| High Resolution  | BW limit + Averaging + Math LPF       | 

10/Jun/2025 Roberto: ROLL Mode
On the MXR the acquisition mode (real-time vs roll) applies globally, not per channel.
If you are using a SYNCH signal as trigger, while viewing its corresponding (slow) signal on another channel:
- In real time the signal may look static, but updates after each trigger.
- In roll mode the SYNCH signal may look under-sampled, but it is still being used to control triggering.
