Preamplifiers
Com-Power broadband high gain preamplifiers were designed for electromagnetic interference (EMI) testing and certification. EMC test labs use preamplifiers to improve sensitivity of the test system during EMI radiated emissions measurements. Without a high gain preamplifier, signals picked by the antenna that have amplitudes below the noise floor of the test system cannot be measured. The preamplifier gain has minimum variations for the entire operating frequency range for accurate emissions measurements. The Com-Power preamplifiers were primarily intended for EMC applications. However, it can be used for other applications that require signal amplification.

Preamplifiers
The primary function of a preamplifier is to extract the signal from the detector without significantly degrading the intrinsic signal-to noise ratio. Three basic types of preamplifiers are available: the current-sensitive preamplifier, the parasitic-capacitance preamplifier, and the charge-sensitive preamplifier. ORTEC manufactures a preamplifier to fit your detector, your application, and your budget.

Charge Integrator Amplifiers
AD8488
Analog Devices’ charge integrator amplifiers convert the charge acquired by X-ray or photodiode detectors to a voltage. The channels are composed of CMOS transistors, using typical high input impedance CMOS gates. The integrators generate charge dependent voltages using a range of selectable capacitance values that accommodate a broad range of input charge values. The integrators are followed by single-ended input to differential output voltage amplifiers where offset and low frequency noise voltages are subtracted from the input voltages.

Charge Meter
NK-1001A/NK-1002A
Probe-type charge meter that can easily measure the amount of discharge charge that causes static electricity destruction in the manufacturing, inspection, and assembly processes of electronic devices.Many ESD phenomena that impair electronic devices are represented by the CDM ( Device Charging Model). The CDM is a model that represents a phenomenon in which a high peak current flows at high speed when the device itself is charged and its external electrode is grounded. The coulomb meter measures the amount of discharge charge, which is the integral value of the current, with high accuracy.
