Figure 11-158Measured rise time percentage error versus signal under test rise time

Although the rise time specification is ≤13 ns, this does not mean that the
P- Series meter and sensor combination can accurately measure a signal
with a known rise time of 13 ns. The measured rise time is the root sum
of the squares (RSS) of the signal under test rise time and the system rise
time (13 ns).
