Characterization of Sources

MXS-EVO was also designed to compare the quality of the different sources provided to apparatus, analyzing the ratio

∆f / f (variation of the frequency value on the nominal frequency) of each source. This analysis is supported by a graph

(that can be generated by the Stability Chart button in the Main Panel) which shows the trend of these ratios over time.

The step used is 5 minutes, while the values are expressed in nanoseconds.

Moreover, is also possible display both on web interface (the View section of Main Panel), and on the LCD screen

(below the status of each source), the delay, expressed in nanoseconds, between the PPS generated from the apparatus

output and the three different tuning sources.

To correctly perform the characterization of various sources it’s good configure the equipment with the following

settings:

• Manual mode exchange

• GPS Source selected

It’s good pratice also expect that the PPS generated by the radio is valid and that its delay is close to 0 ns (visible from

GPS  status).
