Input Equalization
Depending on the hardware version of your system, there are two ways to control input
equalization. One method requires you to set three time constants, or use the defaults.
The other method allows you to select either Hi or Low, or use the default. The method
appropriate for your connected hardware is enabled.
For advanced users only: You can change the values for the “other hardware” by
checking Enable Both Eq modifications. For example, you might want to do this if you
use the same file for both Advisor T3 and Voyager M3i.
3.5.6 USB 3.0 Cabling and Signal Integrity
The Analyzer requires two connector discontinuities. In addition, bus-powered devices
are susceptible to voltage drops on VBus.
To maintain the best possible signal integrity for all devices under test, use high-quality
cabling and use the shortest possible cable lengths. Do not "stress" the system by using
long or low-quality cabling that might result in signal degradation.
If you suspect signal integrity problems in capture situations, you should first try using
shorter and higher-quality cables to see if this rectifies the problem.
