The PMS 221A is a 150 MHz, standard sized, 1:1 and 10:1 switchable passive probe designed for
instruments having 1 MΩ input resistance. This type of probe is recommended for general purpose
probing applications and is adjustable for low 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 PMS 221A features CeramCore
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
switchable probes offer unbreakable coaxial reed switches for changing between attenuation modes.
Our 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. The probes mechanical construction is modular and therefore spare probe leads are
available. See this datasheet and corresponding documents for further details.
