 Environmental Testing  Reliant performance in harsh environments: high relative humidity damp heat, condensation  Wide temperature range PMK introduces a new environmental 10:1 miniature probe for oscilloscopes with up to 350 MHz bandwidth. The Probe is designed to work in harsh environments, where high relative humidity damp-heat and condensation are common, PHT 312 offers reliant performance under such conditions for an ultra-wide temperature range of -55° C up to +155° C. Pure coaxial design and laser trimmed resistors ensure highest signal fidelity along the signal path offering high bandwidths and fast risetimes for accurate impulse measurements. With a maximum input voltage of 300 V CAT II this divider is equally suitable for qualifiying and testing in research 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 Keysight Technologies, Teledyne LeCroy or Tektronix.
