Figure 3–93: Define FFT Waveform Menu
7. Press Set FFT Vert Scale to (side) repeatedly to choose from the following
vertical scale types:
dBV RMS — Magnitude is displayed using log scale, expressed in dB
relative to 1 V
RMS
where 0 dB =1 V
RMS
.
Linear RMS — Magnitude is displayed using voltage as the scale.
Phase (deg) — Phase is displayed using degrees as the scale, where degrees
wrap from –180_ to +180_.
Phase (rad) — Phase is displayed using radians as the scale, where radians
wrap from –p to +p.
The topic Considerations for Phase Displays, on page 3–204, provides in
depth information on setup for phase displays.
