The PHV 1000-3-RO is a 250 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
1000-3-C-RO features CeramCoreTMtechnology. 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 interchange-
able and can be replaced easily. Basic probe accessories and replacement tips are provided within
the scope of delivery or can be purchased separately. The case option includes additional accesso-
ries listed in this datasheet. The probes mechanical construction is modular and therefore spare
probe leads are available. See this datasheet and corresponding documents for further details.

Datasheet
This datasheet supersedes all previously published material. Specifications that are defined typical
are not guaranteed and are published as general information to the user. The instrument should
have warmed up for at least 20 minutes and the environmental conditions must not exceed the spe-
cified limits of the probe. Note that specifications are subject to change without notice.
