DM240XR High-Speed Digital Modulator AutoEQ™ Interface Operation Guide
MN-DM240XR– Revision 13 D–5
EQ ENABLE: {Enable, Disable}
Allows the DM240XR Modulator to implement the AutoEQ™
coefficient values as specified by the EQ Select.
EQ SELECT: {None, User Specified Name}
Allows the DM240XR Modulator to select the stored AutoEQ™
coefficient file to be implemented. Up to 32 User Nameable
storage locations are available.
RXIF: {950 – 2050 MHz}
Sets the receive input center frequency for the AutoEQ™
Interface Card. This programmed frequency must be within +
25
kHz of the actual desired system downlink center frequency to
insure proper acquisition.
MSE: {Value}
Displays the Mean Squared Error (MSE) value of the equalizer.
A value of 1 E-5 or less indicates a successful calibration run
with acceptable coefficients for operation over the satellite.
EQ CAL: {Normal, Calibrating, Ref ACQ}
Allows the DM240XR Modulator to select the AutoEQ™
interface mode of operation.
Normal: When in this state, the AutoEQ™ is in monitoring
mode, with no Calibration or Reference Acquisition functions
being preformed.
Calibrating: When in this state, the AutoEQ™ will program the
DM240XR modulated output for the AutoEQ™ calibration
signal. The calibration output bandwidth is set by the symbol
rate currently programmed into the DM240XR Modulator.
During calibration, the AutoEQ™ will compute the coefficient
values required to successful equalize the group delay and
amplitude of the satellite link over the programmed symbol rate.
During this process, the MSE can be monitored reflecting the
calibration process. Upon successful completion of the
calibration, the EQ CAL will revert to the “Normal” state, and
the event log of the DM240XR will reflect “AutoEQ™ CAL
SUCCESSFUL”.
