Wayne Kerr 3255BQ Inductance Analyzers (20 Hz ~ 1 MHz)

Measurement Function: Z, Ø, L, C, Rac, Rdc, Q, D, turns ratio

Frequency Range: 20 Hz to 1 Mhz

Drive Level:

Source impedance 50Ω

1 mV to 10V rms into open circuit

50 µA to 200 mA rms into short circuit

Automatic Level Control (ALC) maintains level applied to DUT at ±2%, ±1 mV of set voltage or ±2%, ±0.1 mA of set current, reduces to ±4% below 100 Hz.

Internal DC Bias (Option): 1 mA to 1 A

Measurement Speeds: 4 speeds selectable (20/sec max)

Measurement Ranges:

R - 0.05 mΩ to > 2 mΩ

L - 1 nH to >1000H

C - 0.01 fF to > 250mF

Turn Ratio 100:1 to 1:100

Accuracy:

L/Rac/Z/Cp ±0.1%

Q ±0.1% (Q+1/Q)

D ±0.001 (1+ D2)
