PMTG 321A

High impedance passive probe

The PMTG 321A is a 350 MHz, standard sized, 1:1 and 10:1 switchable passive probe designed for

instruments having 1 MΩ 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 PMTG 321A features 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

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.
