PMT211A PMK

PMT 211A High impedance passive probe Features: TM CeramCore hybrid probe Modular construction Coaxial design Interchangeable spring contact tip New IC contacting system for 0.8 to 1.27 mm pitch The PMT 211A is a 250 MHz, standard sized, 10:1 passive probe designed for instruments having 1 M input resistance. This probe is recommended for general purpose 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 PMT 211A features TM CeramCore 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 mini- mizing 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. The probes mechanical construction is modular and therefore spare probe leads are available. See this datasheet and corresponding documents for further details.
