Additional Features:

• 3-digit frequency setting: 10 kHz to 1 MHz (701 spots)
• High speed measurements
• Measure L/C-D/Q/ESR/G, |Z|-q, high speed L/C
• 10-bin component sorting-comparator (OPT.002)
• 0.1% basic accuracy over impedance range of 100 mΩ to 1 MΩ
• GPIB

The Agilent 4277A is a general purpose impedance measuring instrument designed to measure circuit components such as capacitors and inductors using frequency and DC bias conditions identical to those of the intended application.
