The Agilent B1520A Multi-frequency capacitance measurement unit (MFCMU) features AC impedance measurement (C-V, C-f, C-t). 1 kHz to 5 MHz frequency range with minimum 1 mHz frequency resolution. 25 V built-in DC bias and 100 V DC bias with SMU and SCUU (SMU CMU Unify Unit). It uses one slot in a B1500A Mainframe. Specifications.
Measurement parameters: Cp-G, Cp-D, Cp-Q, Cp-Rp, Cs-Rs, Cs-D, Cs-Q, Lp-G, Lp-D, Lp-Q, Lp-Rp, Ls-Rs, Ls-D, Ls-Q, R-X, G-B, Z-q, Y-q. Ranging: Auto and fixed. Measurement terminal: Four-terminal pair configuration, four BNC (female) connectors.
Test signal. Frequency: Range: 1 kHz to 5 MHz. Resolution: 1 mHz (minimum). Accuracy: ±0.008%. Output signal level: Range: 10 mVrms to 250 mVrms. Resolution: 1 mVrms. Accuracy: ±(10.0% + 1 mVrms) at the measurement port of the MFCMU, ±(15.0% + 1 mVrms) at the measurement port of the MFCMU cable (1.5 m or 3.0 m). Output impedance: 50 Ω, typical.
DC bias function. DC bias: Range: 0 to ±25 V. Resolution: 1 mV. Accuracy: ±(0.5% + 5.0 mV) at the measurement port of the MFCMU or the MFCMU cable (1.5 m or 3.0 m) Output impedance: 50 Ω, typical. DC bias monitor: Range: 0 to ±25 V. Accuracy (open load): ±(0.2% of reading + 10.0 mV) at the measurement port of the MFCMU or the MFCMU cable (1.5 m or 3.0 m).
