P6330 3.5 GHz Differential Probe Instruction Manual
If the measurement reading is not stable, use Average mode
(16 Averages) to improve stability.
The system rise time (t
s
) that you measured in step 7 represents the
rise time of the test system without the probe. The system rise time is
used to calculate the probe rise time (t
p
)instep16.
The following steps instruct you to assemble the test setup that
includes the probe, as shown in Figure 21. The system and probe rise
