conductivity caused by condensation must be accepted.

Pollution Degree 3

Conductive POLLUTION occurs or dry, non-conductive POLLUTION

occurs which becomes conductive due to condensation which is to be

Safety and Handling Information

The overall safety of any measurement setup incorporating this probe is the responsibility of the user.

Prevent personal injury, fire and product damage.

To avoid personal injury and to prevent fire or damage to this product or products con-

nected to it, review and comply with the following safety precautions. Be aware that if you

use this probe assembly in a manner not specified the protection this product provides

may be impaired. Only qualified personnel should use this probe assembly.

Use only grounded instruments.

Do not connect the MMCX ground contact to a potential other than earth ground. Always

make sure the probe and the measurement instrument are grounded properly.

Connect and disconnect properly.

Connect the probe output to the measurement instrument before connecting the probe’s

MMCX plug input to the MMCX socket test point in the circuit under test.

Disconnect the probe’s MMCX input from the de-energized circuit under test before

disconnecting the probe from the measurement instrument.

Observe probe and probe accessory ratings.

Do not apply any electrical potential to the probe input which exceeds the maximum ratings

of the probe, or the accessories connected to it. In case of a combination always the lower

rating / measurement category applies to both probe and accessories connected to it.

Keep away from hazardous live circuits.

Avoid open circuitry. Do not touch connections or components when power is present.

Do not operate with suspected failures.

Refer to qualified service personnel.

Indoor use only.

Do not operate in wet or damp environment. Keep the product dry and clean.

Do not operate the product in an explosive atmosphere.

About MMCX Probes

Over the last years MMCX has developed as the standard connectivity solution for repeatable

measurements with highest signal fidelity.

Where traditional passive probes have long ground leads meaning a high inductance causing a ground

loop, the compact MMCX design overcomes these traditional obstacles.

PMK’s MMCX probe series provides models with a very low capacitive loading of less than 4pF for least

capacitive loading and highest signal fidelity with their direct MMCX input.

Different models are available up to >1GHz bandwidthand ±42V input voltagemaking the MMCX probe

series the modern and ideal solution for testing, debugging, and design validation.

Individual Connectivity Accessories for the Highest Signal Fidelity

The MMCX probes series has a universal BNC output connector andis compatible with any oscilloscope

in the lab. Active models MMCX-A require a 50Ω input impedance, or 1MΩ input impedance and a 50Ω

feed-through termination. Passive models MMCX-P require 1MΩ input impedance.

The active probe models require a power supply, which is not included in the scope of delivery, and has

to be ordered separately. Review the Ordering Information at the end of this document for more details.

Factory Calibration

The active probe models are shipped with calibration certificate. For the passive probe models, the

certificate is optional.

Annual re-calibration of the active probes is recommended. ISO17025 calibration upon delivery or as

re-calibration will be possible on request.

Specifications

Read the Instruction Manual before first use and keep it for future reference. A digital copy of the latest

Instruction Manual revision can be downloaded at www.pmk.de.

Do not exceed the specifications. Allow the probe to warm up for 20 minutes. This probe comes with 1

year warranty. Each specification is determined at +23 °C ambient temperature. This probe series is

not rated for CAT II, III or IV.

MMCX Handling Information

When using MMCX connectors, insert the probe’s MMCX plug straight into the mating socket until a

“click” sound occurs to indicate a proper connection between the plug and socket.

When removing the probe’s MMCX input from the MMCX socket, make sure the circuit

under test is de-energized.

Then grasp the probe’s MMCX connector and pull straight out, taking care not to wiggling the

connector side-to-side to prevent excessive stresses on the socket and its connection to the DUT.

Scope of Delivery

A power supply and referring connection cable are required for the active probe models only. See
