Using the Accessories
The 1159A Differential Probe and accessories provide a variety of ways to
connect to circuitry under test. Any method used to connect the probe signal
inputs to the circuit under test degrades the performance of the probing solution.
Take the following precautions to optimize common mode rejection.
• Maintain tip connection lead length as short as possible and the same
length.
• Follow the same path for wires used to connect the inputs of the probe
to the circuit under test.
• Probes do not have infinite input impedance and do load the circuit
under test. If the impedance of the test points is not identical, unequal
loading will occur. This degrades common mode rejection.
• The ground lead length is not usually critical with a differential probe.
• Carefully consider the ground potential relative to the oscilloscope
ground potential. The potential difference must be within the common
mode range of the probe.
• The DC potential between the AC coupling adapter and the
oscilloscope
ground
must not exceed 42 Vpk.
• Do not cascade the external attenuators.
• Cascade the external AC coupling adapter in the following order:
probe
,
attenuator
, and
AC coupling adapter
.
