PMM 311A-RO High impedance passive probe Features:  CeramCoreTM Hybrid Probe  Coaxial Design  Interchangeable Spring Contact Tips 0.8 and 0.38 mm Diameter  IC Contacting System 0.8 to 1.27 mm pitch  Read-out BNC Connector The PMM 311A-RO is a 300 MHz, miniature 10:1 passive probe designed for instruments having 10 MΩ input resistance. This probe is recommended for high performance probing applications and is adjustable for low and high frequencies. The probe is rated with 300 V CAT II maximum input voltage and complies with latest safety standards. Like every PMK passive probe the PMM 311A-RO features CeramCoreTM technology. The probe's entire core is made of a high quality ceramic hybrid. Pure coaxial design and laser trimmed resistors ensure highest signal fidelity along the signal path offering high bandwidth and fast risetimes for accurate impulse measurements. All passive probes are equipped with PMKs signature spring loaded, needle sharp tips to support precise and safe measurements minimizing the risk of slipping off the board and produce a short circuit. Various types of tips are available. Besides the spring contact tips there is also a solid tip available at the users choice. Probe tips are interchangeable and can be replaced easily. Basic probe accessories and replacement tips are provided within the scope of delivery or can be purchased separately. See this datasheet and corresponding documents for further details.

This datasheet supersedes all previously published material. Specifications that are not marked as guaranteed are published as general information to the user. The instrument should have warmed up for at least 20 minutes and the environmental conditions must not exceed the specified limits of the probe. Note that specifications are subject to change without notice.
