Notes
High resolution / C_MODE=1
The high resolution mode increases the resolution/dynamics by approx. 0.5Bit/3dB, but also increases
the power consumption of around 40-50mW. It is recommended to use this mode only if the capacity of the
batteries is still suffcient. The response is unchanged compared to the low power mode.
Amplifier Chopper
The chopper amplifier hacks the signal to rectify it synchronously after amplification. Thus, 1/f noise is largely
avoided. The switching frequency is 1.6kHz. Signal components above 1kHz can lead to aliasing.
PLL_XO=2 & PLL_XO=1
The settings should eliminate gaps by slowly matching the frequencies of the GPS-PPS and the internal oscil-
lator. The PLL_XO=2 option is valid and also used by different groups, while the PLL_XO=1 option, which
would be a full PLL implementation (phase-locked loop), is not available.
