The recommended replacement for models in the 4200 Series is the 4300 Series Model. The 4300 Series Models offers significant improvements over the older models, including:

  • Lower minimum frequency (20Hz)

  • Many more measurement frequencies (557 steps)

  • Extra measurement parameters (Z, Y, θ, B, G, X)

  • Wider AC Drive range (10mV to 1Vrms)

  • Many more AC Drive levels (200 steps)

  • Faster measurement speed

  • DC resistance as a standard feature

  • Larger and easier-to-read display

  • Autoranging AC input voltage

For applications requiring a measurement frequency greater than 100kHz, three additional 4300 models are available:

  • 4320: 20Hz to 200kHz

  • 4350: 50Hz to 500kHz

  • 43100: 20Hz to 1MHz
