4. Known Limitations

- Scope voltage noise floor is not considered.
- Rj values might be higher if the signal has random tone jitter.
- In few cases, the algorithm reports the lower Dj value.
- Maximum Record Length up to 10M is recommended for running the measurements optimally.

-----------------------------------------------------------
5. Known Issues

- In user manual the N start / N stop range is given as 2 to 30, instead of 4 to 30.
