Modulation Analysis
The Modulation Analysis application preset opens the following displays:
Signal Quality: Shows a summary of modulation quality measurements (EVM, rho, Magnitude
Error, Phase Error, and others).
Constellation: Shows the I and Q information of the signal analyzed in an I vs. Q format.
Symbol Table: Shows the demodulated symbols of the signal.

Description
The Modulation Analysis setup application preset provides you with the most common
displays used during modulation analysis. Only present when Option 21 is installed.
The Phase Noise application preset opens the Phase Noise display, and makes changes
to the default parameters to settings better optimized for phase noise analysis. Only
present when Option 11 is installed.
The Pulse Analysis application preset provides you with the most common displays used
during pulse analysis, and makes changes to the default parameters to settings better
optimized for pulsed signal analysis. Only present when Option 20 is installed.
The Spectrum Analysis application preset provide you with the settings commonly used
for general purpose spectrum analysis.
The Spur Search application preset configures the instrument to show the Spurious
display with the frequency range set to 9 kHz to 1 GHz.
The Time-Frequency preset configures the instrument with settings suited to analyzing
signal behavior over time.
Description
The Open the DPX display opens the DPX display without closing existing displays.
The DPX Real Time Preset displays the DPX Spectrum display with the center frequency
set to 1.5 GHz and the span set to the maximum available real-time bandwidth.
The DPX Swept Preset displays the DPX Spectrum display with the center frequency
set to 1.5 GHz and the span set to 3 GHz.
The DPX Zero Span Preset displays the DPX Zero Span display with the center
frequency set to 1.5 GHz and the sweep set to 1 ms.
Description
This Preset sets the instrument to display a Spectrum display with settings matched
to show a Spectrum display with settings appropriate for typical spectrum analysis
tasks. This preset was updated from the original factory preset with version 2.4 of the
instrument software.
This Preset is the original factory preset used with software versions 1.0 through 2.3.
This version of the factory preset is included to allow users to maintain compatibility with
existing remote control software.
