PMK introduces a new universal 10:1 miniature probe for oscilloscopes with up to 350 MHz band-
width. As all PMK probes the PML 311 features CeramCore
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. With a maximum input voltage of 300 V CAT II this divider is equally suitable in ser-
vice and development environments. The new probe is also available with read-out BNC connector
to be automatically recognised as 10:1 divider by scopes that feature a sense ring to detect probe
attenuation such as Agilent, LeCroy or Tektronix.
The compact design of this new probe with its 2.5 mm housing diameter at the tip provides better
visibility to the DUT (device under test) in dense SMT circuits than conventional 5 mm housings.
Due to the remarkably low input capacitance the signal source is only loaded by 10 pF. Less load to
the measurement circuit can only be achieved with active probes. Especially when measuring
signals with fast rise times often the probe‘s adaption to the source signal plays an important role.
Long ground leads found on most conventional adaptions bring additional inductance and resonan-
ces into the setup which will result in false or inaccurate readings. The new IC contacting system
consisting of five different IC adapters ranging from 1.27 to 0.5 mm pitch and the PCB adapter kit
offer an ideal solution for short circuit-proof, reproducible measurements. As you would expect the
probe is shipped with PMKs signature spring-loaded tips. In total there are 16 different accessories
included in the scope of delivery with the new PML 311 offering adaptive solutions for almost every
probing demand.
