Reference Position (X Scale)

(applies only to Real vs. Imag trace format)

Range: 0 to 100%

Reference Level sets the position of the invisible, vertical reference line within the trace grid. 0% indicates that the reference line should be at the left edge of the trace grid, and 100% indicates that the reference line should be at the right of the trace grid.

To set the actual value of the reference line (for example, -3 dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated in the nominal input impedance of the analyzer), use the Reference Position parameter.
