Keysight-Agilent 4270A

The 4270A Automatic Capacitance Bridge automatically measures capacitance, equivalent parallel conductance, and dissipation factor. Conductance ranges from 899.9 nmhos to 8.999 mmhos. Offers 5-digit readout of capacitance from full-scale ranges of 18.000 pF to 1.2000 ?F with 0.001 pF resolution and measurement speed of 0.5 seconds. Four measurement frequencies from 1kHz to 1MHz. Basic accuracies (?n% of reading + number of digits): capacitance (0.2-0.5 + 1), conductance (1-3 + 10), dissipation [1-3 + (10 + internal capacitor/capacitance measured)].
