Overview Control elements and resourcesTo define a spectral math waveform
Set the phase
scale
12. Select the Phase tab.
13. To select the vertical scale f actor click Scale:
H Degree to set the phase units to degrees. Phase is
displayed using degrees as the scale, where
degrees wrap from --180_ to +180_.
H Radian to set the phase unit s to radians. Phase is
displayed using radians as the scale, where radians
wrap from --π to +π.
H GroupDelay to unwrap the phase spectrum and
display its derivative.
The topic Using the Phase Controls on page 3--158
provides in-depth information on setup for phase
displays.
14. To specify whether to unwrap phase in a spectral
analysis phase waveform, click Unwrap t o toggle.
15. To set the level in dB that a magnitude in the spectrum
must exceed to have its phase computed (to reduce the
effect of noise in your phase waveform), click
Suppression Threshold, and use the multipurpose knobs
or pop-up keypad to set the threshold level. If the
magnitude is less than the threshold, then its phase is
set to zero (for an example, see Figure 3--47 on
page 3--159).
The topic Suppression Threshold, on page 3--159
provides additional information on phase suppression.
Set time and
frequency
domain
control
tracking
16. Select the Control t ab.
17. To enable changing time and frequency domain controls
for one math waveform to change the same controls for
another math waveform, click the Track Time/Freq
Domain Controls buttons to toggle them on or off.
