1. ECal modules don’t cover the whole frequency range of the E5061B. Check whether
the frequency range of each ECal module meets your measurement needs
2. Only on 4-port models.
3. Segment includes sweep types that are known as list and fast swept list.
4. Option E5071C-xx5 (with bias tees option) is required. Minimum frequency is
100 kHz for Options x45 and x85.
5. Time domain gating is not supported.
6. Dir = directivity; SM = source match; LM = load match; Refl trk = reflection tracking;
Trans trk = transmission tracking
