Data Collection Parameters:

Item Default Value Min Max Comment
Time window 80 3.5 192,000 ns Min and max time window are governed by the min and max points per trace and so depends on the time sampling interval. Daisy-chained NICs limited to 2000ns max
Points per trace 200 70 30000 Points per trace must be set the same for the GPRs on a single NIC. Points per trace can be different between NICs on a daisy chained system.
Time sampling interval 400 50 None Time sampling intervals override the usual fixed time sampling intervals of Noggins which are:
Noggin 100 = 800ps
Noggin 250 = 400ps
Noggin 500 = 200ps
Noggin 1000 = 100 ps
Stacks 4 2 32868 Stacks must be set the same for the GPRs on a single NIC. Stacks can be different between NICs on a daisy chained system.
Number of Traces per GPR line N/A 1 1,000,000 or 200 MB
