PML311

PML 311 High impedance passive probe Features: 2.5 mm diameter tip TM CeramCore hybrid probe Coaxial design Interchangeable spring contact tip New IC contacting system for 0.5 to 1.27 mm pitch PMK introduces a new universal 10:1 miniature probe for oscilloscopes with up to 350 MHz band- TM width. As all PMK probes the PML 311 features CeramCore technology. The entire probe 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. 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 probes 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.
