Q[3]
is a [3] bin loading of a sample distribution of the IF/BB signal for Q-channel (in
%).
Q[-3]
is a [-3] bin loading of a sample distribution of the IF/BB signal for Q-channel (in
%).
Gain
is an amount of gain signals.
Rail
is an amount of rail signals.
Meas
is an amount of meas signals.
Cnt
is a value of a counter that is increased at every gain change on I, Q or both
channels.
Start
is a return value of AGC_start API in GE867-AGPS firmware
(0 – success, 1 - failure).
Stop
is a return value of AGC_stop API in GE867-AGPS firmware
(0 – success, -1 - failure).
Example:
$PUNV,AGC,35,35,51.7,51.7,30.8,33.5,17.3,18.4,30.8,33.5,17.3,18.4,4,0,0,5,0,0*75

CLKOFFSET
This message provides the master clock offset data
$PUNV,CLKOFFSET,
nn.nnnnn
,
fff.fff
*cc
nn.nnnnn
is a floating point number representing a nominal clock frequency (TCXO
frequency) in MHz.
fff.fff
is a floating point number representing a current clock offset in Hz, in relation to
the nominal clock frequency.
The current measured absolute clock frequency is then (
nn.nnnnn
+
fff.fff
/1e6) in MHz.
Example with about 0.5ppm offset over 16.3676MHz nominal clock frequency:
$PUNV,CLKOFFSET,16.36760,8.126*cc
