HIGH FREQUENCY DC BIAS
6565 SERIES
The 6565 HF DC Bias Unit is intended to be used with a Wayne Kerr 6500 analyzer, either the 6500B Precision Impedance Analyzer or the 6500P HF LCR Meter. Its function is to provide a source of DC bias current through the Device Under Test (DUT) while the analyzer is making AC measurements. Each 6565 unit can provide up to 10 A of DC current, and up to six 6565 units can be connected in parallel to supply a maximum 60 A. A digital ammeter on the front panel allows the user to see the dc bias current value and an indicator LED shows when the bias current is enabled.

AC Voltage and Frequency Transducers
NMTU/F
The NMTU/F device is an AC voltage and frequency transducer with two independent analogous outputs. The A output measures AC voltage, the B output measures the frequency of input voltage. That´s why one single NMTU/F transducer is able to replace two customary transducers, thus making it possible to achieve significant savings in installation space.

Reference Magnet
Reference magnets generate a homogeneous magnetic field in an air gap. They are mainly used to calibrate hall probes for their full scale value of output for the magnetic field strength H or the magnetic flux density B they measure. For example Gaussmeters can be calibrated by using reference magnets.

High Frequency Clock Divider Board
Alliance Support Partners, Inc.
Clock Divider is designed to divide high frequency signals, up to 2.5GHz, from 4 to 256 times. It will accept single ended (Unbalanced) or differential (Balanced) signals with amplitudes as little as 100mV rms. The clock division is controlled by 4 shunt jumpers. The circuit can be disabled and the divide by counter reset with 2 control signals. The on board regulator will accept voltages from 4.85 to 15.0V. The output is capable of driving 700mV Peak to Peak into 50 Ohms.
