Graphical User Interface Overview (Continued)
Spacing measurement
Easily measure the space between pulses when a long pulse train occurs. The 8990B
allows users to select the starting pulse and the end pulse, a function that is important
in pulse block validation. R&D engineers may use this function to detect potential
abnormalities in certain pulse groups, and whether those abnormalities are repeated in
a long pulse train.
Zoom screen
The 8990B provides dual window zoom capability. When this function is enabled, the
top screen will display the original signal, while the bottom screen displays the enlarged
signal trace.
To focus and zoom in on a particular segment of the signal trace, use the white zoom
box to select the area of interest on the original signal trace. The measurement panel
below will display the results of the selected signal segment. This function provides R&D
engineers the flexibility to focus on particular parts of the signal and to obtain only the
measurement results they need.
The dual zoom window capability allows users to observe the original trace while
focusing in on the selected signal segment instead of flipping between screens or losing
the original trace after zooming in on the segment.
Threshold/power display settings and erase memory
The 8990B allows users to change channel settings. The default threshold setting is
90% and 10%; however, users may change the reference levels to any value. If a pulse
has high overshoot in the traces, users can choose to reduce the upper trace level to
80% or 70% to eliminate the overshoot signal’s impact on the results. Users can also
modify the trace level of two different signals for the delay measurement according to
what is the best reference level for the individual signal.
Users can also change their settings to display power measurements in either
logarithmic or watts to help with easy result conversion or to match the results to the
traces in the graphical window.
For users in the aerospace and defense industry, the 8990B offers several ways to
secure both data and measurement settings such as the memory sanitization feature,
a standard product feature in all Keysight equipment that will erase the system’s setup
and data results. Users can also opt for the removable hard drive option, which switches
the attached hard drive with a removable version, so users can remove data and settings
together with the hard drive without worrying about information leaks.
