tion menu will be opened. With the first and the third soft
menu key OPERAND, you can choose the respective chan-
nel (source) for the mathematical calculation. You may only
choose activated analog channels. The central soft menu
key OPERATOR allows you to select the calculation type.
Following calculation types (OPERATOR) can be selected:
You can use the universal knob in the CURSOR/ MENU
section to select operands and operators.
9 .1 .2 Formula Editor (MA)
The formula editor menu of the R&S®HMO1202 series
(soft menu key MA) allows you to activate and deactivate
mathematical equations which are defined and displayed
within the selected formula set. The MENU key in the VER-
TICAL control panel opens a menu to select the formula
set and its corresponding formulas. The R&S®HMO Com-
pact series includes five mathematical formula sets. Each
of these formula sets contains five formulas which may be
edited with a
formula editor to also define linked
mathe-
matical functions. These are labeled MA1 to MA5. You can
use the universal knob in the CURSOR/MENU section to
select the formula set. The formula set editor (soft menu
key EDIT FORMULARY) lists all existing equations which
may be edited. A blue bar indicates that an equation is
selected. It is important to distinguish between editing the
display and editing the parameters. Use the universal knob
in the CURSOR/MENU section to select the respective
equation and activate by pressing the soft menu key VISI-
BLE. An activated, visible equation is marked by a filled-in
eye symbol in the formula editor and is listed in the short
menu. With the soft menu UNIT you can use the universal
knob in the CURSOR/MENU section to select the following
units:
Addition
(ADD)
Subtraction
(SUB)
Multiplication
(MUL)
Division
(DIV)

9 Analysis
The R&S®HMO1002 resp. R&S®HMO1202 series features
different analysis functions for the collected data records
which are displayed on the screen. Simple mathemati-
cal functions can be performed with the mathematical
function while more complex functions and the linking of
functions can be accomplished with the formula editor
(only with R&S®HMO1202 series). The MATH menu inclu-
des mathematical functions for the recorded signal types.
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.
9 .1 .1 Quick Mathematics (QM)
Pressing the MATH key in the VERTICAL section will acti-
vate the math short menu. The lowest soft menu key ac-
tivates the Quick Mathematics (QM) or the formula editor
(MA). In the QM short menu the configuration of the math
function can be selected with the soft menu key. Pressing
