Preparation for Use
Power requirements
If using the probe with an instrument that does not supply probe power, you can
purchase an 85024A-001 adapter cable assembly and one of the following
Keysight external power supplies:
– E3620A
– E3630A
– E3631A
You need to ensure the correct setting of the power supply (+15 V and –12.6 V)
per attached labels on the 85024A-001 adapter cable assembly.
Electrostatic discharge (ESD), excessive input signals, or mechanical shock
can dramatically degrade the performance of the probe. Be sure to observe
the following precautions.
– Never touch the tip of the probe!
– Always hold the probe by the retracted metal sleeve.
– Work at a workstation equipped with an anti-static mat.
– Extend the protective sleeve when not actually taking measurements.
– Wear an anti-static wrist strap and avoid introducing static electricity into
the device under test (DUT) or test setup.
– Make sure the device under test (DUT) is at the same ground potential as
the probe.
