Center frequency
Frequency offset
Frequency range (0 Hz with zero span and statistics
measurements)
Scaling of x axis linear (LIN) or logarithmic (LOG)
Start/stop of the display range.
Unit:
Hz for span > 0, s for span = 0,
dBm/dB for statistics measurements
Reference level
Level offset
Position of reference level referred to diagram limits
(0% = lower edge)
Scaling of y axis linear (LIN) or logarithmic (LOG)
Display range in in y direction. Unit: dB with x axis LOG,
% with x axis LIN
Input attenuation

Selected trace
Unit of x values:
Hz with span > 0; s with span = 0;
dBm/dB with statistics measurements
Unit of y values:
dB*/V/A/W depending on the selected unit with y axis
LOG or % with y axis LIN
Number of test points
Measured values:
<x value>, <y1>, <y2>
<y2> being available only with detector AUTOPEAK and
containing in this case the smallest of the two measured
values for a test point.
