5.10 Format Softtool
The "Format" softtool allows you to define how the measured data is presented in the
diagram area.
Access: TRACE – FORMAT hardkey
Measured quantities and display formats
The analyzer allows arbitrary combinations of display formats and measured quantities
(see
Chapter 5.9, "Meas Softtool" , on page 435). Nevertheless, in order to extract use-
ful information from the data, it is important to select a display format which is appropri-
ate to the analysis of a particular measured quantity.
An extended range of formats is available for markers. To convert any point on a trace,
create a marker and select the appropriate marker format (see
"Marker Format"
on page 535). Marker and trace formats can be applied independently.
Background information

dB Mag
Selects a Cartesian diagram with a logarithmic scale of the vertical axis to display the
magnitude of the complex measured quantity.
Properties: The stimulus variable appears on the horizontal axis, scaled linearly. The
magnitude of the complex quantity C, i.e. |C| = sqrt ( Re(C) 2 + Im(C) 2 ), appears on the
vertical axis, scaled in dB. The decibel conversion is calculated according to dB
Mag(C) = 20 * log(|C|) dB.
