The PHV 1000-RO is a 400 MHz, standard sized, 100:1 passive probe designed for instruments having 1 MΩ input resistance. This probe is recommended for probing applications in service and development environments and is adjustable for low and high frequencies. It is also recommended for transient measurements up to 6 kV such as EMC testing applications. The probe is rated with 1000 V CAT II maximum input voltage and complies with latest safety standards. The DC fine adjustment enables trimming for preferred voltage ranges. Like every PMK passive probe the PHV 1000-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. Various types of tips are available. Besides the spring contact tip 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.
The PHV 1000-RO passive probe from PMK offers a 400 MHz bandwidth and a 100:1 attenuation ratio, suitable for high‑frequency and transient measurements up to 6 kV. Its modular, coaxial design includes interchangeable spring‑loaded tips and optional solid tips, providing flexibility for various measurement tasks.
The datasheet details electrical specifications such as system bandwidth, risetime, input resistance and capacitance, as well as mechanical characteristics like weight (67 g), cable length (2 m) and tip diameter (5 mm).
