Rise time
This procedure veri
fi
es that the probe meets the rise time speci
fi
cation. Two rise times are measured; the test system alone, and
then the test system with the probe included. The probe rise time is calculated using the two measurements.
This test uses the TDR function of the 80E04 sampling head as a fast rise time signal source. A second 80E0X sampling head
is used to take the measurements. Although the following procedure assigns the TDR and measurement functions to speci
fi
c
oscilloscope channels, any channels can be used. However, the TDR function is only available on 80E04 sampling heads.
CAUTION.
To prevent damage, use care when working with SMA connectors: support equipment to avoid mechanical strain on
the connectors, and when tightening connections, use a torque wrench to 7.5 in-lbs.
