Graphical User Interface Overview
Measurement screen
The main measurement screen is capable of displaying up to four traces: two
RF traces, and two video traces (the triggering signal). Results are shown in the
panel directly under the graphical window, with measurements displayed in the
same color as the channel it corresponds to. When a USB sensor is connected,
the results for this additional channel can be overlaid on the same graphical
window in compact mode, The main screen also features a soft panel key to the
side of the graphical window, which lists the 15 pulse characterization measure-
ments for quick measurement analysis. Users can select these measurement
parameters via the touchscreen display, or by using the mouse.
Delay measurement
Users can perform delay measurements by pressing the Delay Measurement
button on the soft panel key. Two vertical markers will automatically detect the
first pulse of the traces. The time delay between the two traces will be displayed
in the measurement panel below the graphical window.
Droop measurement
The 8990B is the first peak power analyzer on the market that offers automated
Pulse Droop measurement, eliminating the need to manually manipulate the
horizontal markers to make this measurement. The Pulse Droop measurement is
accessible via the soft panel key, and measures the amplitude degradation of the
pulse top.
