The HP/Agilent 43961A RF Impedance Test Kit is a specialized accessory that extends the impedance measurement capabilities of compatible network, spectrum, and impedance analyzers. Using direct current-voltage (I-V) measurement techniques, the kit characterizes one-port devices with superior accuracy across wide impedance ranges, particularly for devices whose impedances deviate significantly from system characteristic impedance.
Technical Specifications
The kit operates across two frequency ranges depending on host analyzer selection: 100 kHz to 500 MHz with the Agilent 4395A (Option 010), or 100 kHz to 1.8 GHz with the Agilent 4396B (Option 010). The test port features a 7-mm connector compatible with optional test fixtures.
Measurable parameters include impedance magnitude and angle (|Z|, θ, R, X), admittance characteristics (|Y|, G, B), capacitance (Cp, Cs), inductance (Lp, Ls), resistance (Rp, Rs), dissipation factor (D), quality factor (Q), and reflection coefficient (|Γ|).
– Key Features
The I-V measurement method delivers consistent accuracy without the impedance-dependent errors inherent in reflection coefficient approaches. The kit includes OPEN, SHORT, and LOAD calibration standards for baseline accuracy establishment. Fixture compensation and port extension capabilities minimize systematic measurement errors.
External DC bias voltage application is supported through a dedicated connector, enabling biased-condition measurements. The kit provides five equivalent circuit function types for direct extraction of circuit component parameters from measured data.
– Typical Applications
Ideal for engineers characterizing component impedance across RF frequencies, analyzing resonant circuits, measuring capacitor and inductor behavior under load conditions, and extracting equivalent circuit parameters for device modeling.
– Compatibility & Integration
The 43961A pairs with HP/Agilent 4395A and 4396B analyzers equipped with Option 010. Included components are the impedance test adapter (43961-61001), three calibration standards (04191-85300, 04191-85301, 04191-85302), N(m)-N(m) cable (41951-61602), carrying case (43961-60001), and documentation (43961-90000).
