[f3] IFBW = 10 Hz.
[f4] Except phase wrap aliasing (example: a DUT group delay of 5 ns (1 m cable length) requires a frequency step size of ≤0.2 GHz to avoid phase wraps). Excluding a
constant group delay offset of <±0.3 ns typ. (cable length uncertainty <±0.06 m). A constant group delay offset leads to a phase offset∆φ = 360° × ∆GD × fmod.(in deg).
[f5] After CW responsivity and user calibration with external source.
[f6] Requires option -101 or -102.
[f7] Typical with internal source.
[f8] Average value over frequency range.
