characteristics of the external attenuator itself do
not exactly match those of the probe. Therefore,
using the ÷10 and ÷20 attenuators at the same
time is not recommended. The scale factor
encoding system will not operate correctly with
both attenuators installed simultaneously.

external attenuators currently supplied with the
probes are labeled with the appropriate model
number. The attenuators supplied with model
AP033 probes prior to the introduction of the
AP034 did not include the model number on the
label. When using an external attenuator with the
AP034 Active Differential Probe, make sure it is
labeled "AP034."
Interchanging non-compatible attenuators will
not damage the probes; however, the transient
response of the measured signals will be
significantly in error.
In addition to being compatible with the included lead set, the
probe input connectors will mate with standard 0.025 in.
(0.635 mm) square pins in any rotational orientation. To avoid
damaging the input connectors, do not attempt to insert
connectors or wire larger than 0.036 in. (0.91 mm) in diameter.
Avoid rotating square pins after they are inserted into the input
connectors.
The included accessories simplify the task of connecting the
probe to the test circuit:
•
Use the small (0.5 mm) mini clips with the flexible
lead set when connecting to fine-pitch surface mount
IC leads.
