The R&S®HMO3000 series features different analysis func-
tions for the collected data records which are displayed
on the screen. Simple mathematical functions can be
performed with the mathematical function while more
complex functions and the linking of functions can be
accomplished with the formula editor. The MATH menu
includes mathematical functions for the recorded signal ty-
pes. The mathematical functions track the changes of the
included signals and only apply to the visible area. You can
also activate the frequency analysis (FFT) by pressing the
respective key. The function QUICK VIEW provides a quick
overview for the signal properties. A masked-based PASS/
FAIL test allows you to monitor signals automatically.
9.1 Mathematical Functions
The MATH menu in the VERTICAL section includes ma-
thematical functions for the recorded signal types. The
mathematical functions track the changes of the included
signals and only apply to the visible area.of the screen. If a
signal is cut off at the edge of the screen may indicate that
the corresponding mathematical curve is also truncated.
The VOLTS/DIV knob can be used to scale an activated
mathematical curve.
The MATH menu includes the Quick Mathematics (QM)
and formula sets (MA). Quick Mathematics is designed
for simple and quick calculations. The formula sets allow
formular combinations.
