What does the HP428X LCR Meter do?
The HP428X LCR Meter is most commonly used to perform impedance parameter measurements on a circuit or device, as a function of frequency, DC bias voltage, or oscillation level. For instance, the impedance can be measured as a function of swept frequency (range = 5 Hz to 13 MHz) at a fixed voltage, or as a function of swept DC bias (range = -35V to +35V) at a fixed frequency. The HP428 simultaneously measures two independent, complementary impedance parameters in each measurement cycle.
