Vector Impedance Meter
The 4193A measures impedance magnitude and phase. An internal oscillator provides test signals from 400 kHz to 110.0 MHz. The test signal is a constant current between 10µA and 100µA, depending on |Z| range.
Features
- Test components in-circuit and out-of-circuit
- Measure impedance magnitude (10 mΩ to 120 kΩ) and phase (-180.0 to +180.0)
- Fixtures include low-grounded probe, spring clip fixture, and binding post fixture
- Standard HP-IB and analog ouputs
