4.2.8 Spread Spectrum Control Section

The Spread Spectrum Controls Section allows the user to control features related to spread spectrum and managing electromagnetic conductivity/interference.

By default, spread spectrum is enabled. This can be disabled by clicking on the Spread Spectrum Enabled button. To re-enable, simply click the box again.

Another button found in this section is the Automatic Channel Phasing. By default Automatic Channel Phasing is disabled but can be enabled the same way as Spread Spectrum is.

The three drop-down menus, Dephase Ch2 to Ch1, Dephase Ch3 to Ch1, and Dephase CH4 to Ch1, all control the channels output phases from each other. Each can be set to be either 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees or 315 degrees out of phase from channel 1. The default values for Dephase Ch2 to Ch1, Dephase Ch3 to Ch1, and Dephase CH4 to Ch1 are 180 degree, 90 degree, and 270 degree, respectively.
