PHT 312 is suitable for environmental testing and other applications, that entail rough testing conditions.


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 service and development environments. The system-independent 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, Rohde & Schwarz, Teledyne LeCroy or Tektronix.
