2. Comparison sequence
The comparison was led by LNE as part of the Club nanoMétrologie ("Instrumentation" technical group) and took place in 2014 and 2015.
As this comparison involved a large number of participants (26 in all), it was decided to circulate two batches of samples, each comprising a P900H60 network and a VLSI standard. A back-up batch was also provided in case of package loss or network damage during the comparison.
Figure 4 explains how the comparison is organized in three stages:
