PMM511A PMK

PMM 511A High impedance passive probe Features: TM CeramCore hybrid probe Coaxial design Interchangeable spring contact tips 0.8 and 0.38 mm diameter New IC contacting system for 0.8 to 1.27 mm pitch The PMM 511A is a 500 MHz, miniature 10:1 passive probe designed for instruments having 1 M 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 511A 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. See this datasheet and corres- ponding documents for further details.
