Functionality of the Mercury6e
Frequency Units
All frequencies in the M6e are expressed in kHz using unsigned 32-bit integers. For
instance, a carrier frequency of 915 MHz is expressed as 915000 kHz.
The PLL is set automatically to the closest frequency - based on the minimum frequency
quantization for the current region - that matches the specified value. The M6e has an
absolute minimum quantization of 25 kHz. Each region also has a minimum quantization
based on regulatory specifications, which may be greater. The following table details the
frequency quantization in kHz for each region setting.
Regional Frequency Quantization
When manually setting frequencies the module will round down for any value that is not
an even multiple of the supported frequency quantization.

It is possible to change the moduleʼs com-
pliance with the regional regulations.
