2 Using the N7020A

Requirements for Optimum Probe Performance
Low Source Impedance Required
Minimize Probe Ground Impedance for the Best Signal Fidelity
Common Types of Power Integrity Measurements
Connecting to the DUT
Avoiding Costly Repairs
This chapter explains requirements for using the probe, how to connect the probe
to the Device Under Test (DUT), and how to protect the oscilloscope and probe
from damage due to ESD.
Always wear an ESD wrist strap when working with active probes. Not doing so can result
CAUTION
in damage to the probe and to the oscilloscope's input channel.
If the N7020A input is connected to an S-series oscilloscope at vertical settings at or below
NOTE
20 mV/div with more than 200 mV of applied offset with no signal on the probe input, the
probe output may be indeterminate. Upon zeroing the offset, increasing the vertical setting, or
connecting the probe input to a low impedance (power rail), the output will be correctly
restored.
