FarSync BERT - Calibration
The only calibration that your FarSync BERT requires is to verify the correct
operating frequency of the internal crystal oscillator used for clock
generation.
This can be performed without disassembling the unit by measuring the generated
clock at the DCE interface.
It is recommended to test your BERT's calibration annually.
You will need:
To calibrate your FarSync BERT:
Using these settings the expected voltage swing is nominally 0-5V, when unterminated,
and the expected measured frequency is 1.024MHz with a variation tolerance of ±100ppm
for FarSync Flex V1 or ±25ppm for FarSync Flex V2 and above. If the measured frequency
falls outside these limits, the device should be returned to FarSite for recalibration,
using the standard FarSite returns procedure. Please contact FarSite support at
support@farsite.com if you have any
queries.
