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). 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”.
