Signal Conditioning Unit

The SCU-100 Signal Conditioning Unit takes a composite input signal, splits the signal into its broadband AC and low-pass DC signals, amplifies these signals, then applies the amplified signals to AC and DC outputs.

The AC output voltage can be determined using a lock-in amplifier and a digital voltmeter and can be used to measure the DC output voltage. The ratio of the AC to DC voltage is a necessary computation for the measurement of linear and circular dichroism.

The SCU-100 provides signal amplification via AC and DC gain controls, which is useful in many experimental setups. A 9 volt, 150mA detector power output is provided for powering the Hinds Instruments detector/preamplifier units.
