3 IQ Analyzer (Basic) Mode
3.1 Complex Spectrum Measurement
I/Q Waveform
The I/Q Waveform Window shows the I and Q traces of the input signal in the time
domain.
Marker Trace Yes
Corresponding
Trace
Returns the averaged trace data of log-magnitude versus time, (that is, the RF
envelope) (n=5)
The I/Q Waveform window in the Normal View, is as follows:
View Size Position
Normal 1/3 height, full width Bottom
3.1.3 Amplitude
Activates the Amplitude menu and selects Reference Level or Reference Value as
the active function, depending on the measurement.
Some features in this menu apply to multiple measurements. Some other features
apply only to specific measurements and their controls are blanked or grayed-out in
measurements that do not support the feature.
3.1.3.1 Y Scale
Contains controls that pertain to the Y-Axis parameters of the measurement. These
parameters control how data on the vertical (Y) axis is displayed and control
instrument settings that affect the vertical axis.
Ref Value
Enables you to set the value for the absolute power reference. The reference line is
at the top, center, or bottom of the graticule, depending on the value of the "Ref
Position" on page 149 function.
