REF ACQ:
Although default reference files are provided, the
operator may wish to acquire the best possible reference from
their modulator. A mechanism to accomplish this is allowed by
REF ACQ, this overwrites the stored default and replaces it with
a new reference. Prior to entering this state, the L-Band output
of the DM240XR (J11) must be connected to the AutoEQ™
RXRF Input (J12) as shown in Figure . The DM240XR Output
power should be set to -20 dBm, and a 20 dB in line attenuator
should be used. The Modulator output frequency should be set
to set to the corresponding AutoEQ™ RXRF Input Frequency.
When properly connected and 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 reference calibration, the AutoEQ™ will
obtain receive lock and establish the baseline coefficients for
internal reference. References are captured for each modulator
roll-off and oversample rate. During this process, the MSE can
be monitored reflecting the Reference Acquisition process.
Upon successful completion of the Reference Acquisition, the
REF ACQ will revert to the “Normal” state, and the event log of
the DM240XR will reflect “REF ACQ SUCCESSFUL”.
