MEASERR is the last measured time offset of the CDMA Subsystem to CDMA while
locked, in seconds.
TIMEDEV is the time deviation (TDEV) of the offset measurements in seconds. The tau
associated with this measurement is one second, which is the update interval
of the position xes received from the CDMA Receiver.
AGERATE is the regression-computed system oscillator ageing rate per day (several-hour
delay before the rst measurements are displayed).
TAU is the system oscillator control loop averaging time constant, in seconds. It’s
value is automatically adjusted to maintain optimum system clock offset and
stability.
EFCDAC is the system oscillator Electronic Frequency Control 20-bit DAC value. The
system automatically sets this value to remove frequency errors. Values may
range from 0 to 1048575. Values close to the maximum or minimum will set the
DAC fault ag that will appear in the fault status display. The Time/Status dis
play will also indicate a fault condition.
TEMP is the chassis internal temperature in °C.
