R3267 Series Spectrum Analyzer Operation Manual (Vol.1)

4.4.2 Calculation using the Measurement Window

4-10

4.4.2

Calculation using the Measurement Window

When displaying the measurement window and performing the eye opening measurement, the maximum
and minimum amplitudes A and B are calculated from the waveform data included in the measurement
window shown in Figure 4-9.

The maximum and minimum time periods A’ and B’ are calculated from the waveform data located by the
Y cursor on the screen.

Figure 4-9 Eye Opening Calculation (Using the Measurement Window)

Y cursor

X cursor

A’ and B’ are calculated from
the waveform data located
by the Y cursor.

A and B are retrieved
from the measurement window.
