3.6 Mathematical Settings
In addition to cursor and automatic measurements, the
R&S®HMO3000 series can also apply mathematical ope-
rations to the signals. Pressing the MATH
26
key opens
a menu enabling you to apply addition, subtraction, mul-
tiplication or division to two analog channels. This also
displays the mathematical graph. The top soft menu key
allowsyoutoselecttherstoperand.Withthekeybelow,
you can select the operator. The soft menu key below that
allows you to select the second operand. Only activated
and displayed channels are available for the operands. The
sources selected in the function must be activated so that

3.5 Automatic Measurements
In addition to cursor measurements the most important si-
gnal parameters can be displayed. Your oscilloscope offers
these possibilities:

Quick display of all important parameters of one source
by use of the QUICK VIEW feature
Please change the time base to 100 µs per scale division
and press the QuickView
10
key. You will see the most im-
portant parameters of a signal displayed:
positive and negative peak voltages
rise and fall times
mean voltage
10 additional parameters are shown below the grid:
RMS,
peak-peak voltage,
frequency,
period,
amplitude,
number of rising edges,
pos. pulse width,
neg. pulse width,
pos. duty cycle,
neg. duty cycle.
For this option, press the Quickview
