A slope will be counted if the signal runs through the
mean value. The measurement will only be applied to the
selected channel.

COUNT –/ : This mode counts signal changes
(slopes) from High Level to Low Level in the
displayed view of the screen. The mean value is

The automatic measurement results are displayed at the
bottom of the screen. If “n/a” is displayed, the measurement
is not applicable to the signal. For instance, this may be the
case for a voltage measurement on a POD because only
logic states without voltage reference are displayed here.
If “?” is displayed, the display does not show a complete
measurement result. For instance, the period to be measu-
red may not display completely and can consequently not be
identified.

9 Analysis
The R&S®HMO1002 features different analysis functions
for the collected data records which are displayed on the
screen. Simple mathematical functions can be performed
with the mathematical function. 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 al-
lows 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 short menu allow you to configure the ma-

MENU key in the VERTICAL section will switch you to a
more detailed display of the MA menu. With the first and
the third soft menu key, you can choose the respective
channel (source) for the athematical calculation. You may
only choose activated analog channels. The central soft
menu key allows you to select the calculation type. Fol-
lowing calculation types (OPERATOR) can be selected.
