ORTEC
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.

Com-Power Corporation
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.

Physical Acoustics Corp.
Preamplifiers recognize the extremely low amplitude AE signal produced from AE sensors, and convert the signals into amplified and usable forms. As applications and testing conditions vary, project needs may change as well. Physical Acoustics offers an entire line of preamplifiers for a variety of testing requirements. Operating in conjunction with our specialized AE software, preamplifiers also moderate signal size during the data collection process, helping to produce accurate results.

A.H.Systems, Inc.
A.H. Systems'' Preamplifier line is an excellent choice with a rugged design, no hassles with soldering your own power leads and they improve overall system sensitivity by at least 20 dB. All of A.H. Systems'' Preamplifiers come with a 12-volt (or 15-volt) DC regulated power source. A low voltage indicator confidently allows you to power the amplifier with your own external 12-volt DC battery. This makes it a convenient choice for field measurements. See table below for amplifier specifications.

Teseq AG
Low noise amplifier with 12.5 dB of gain covering the nominal frequency range 1 MHz to 3 GHz and can be used in the range from 200 kHz to 4 GHz. With its high gain and low noise figure, it will significantly increase the sensitivity of virtually all spectrum analyzers and other RF measuring instruments. All measuring instruments have a 'noise figure', which is a measure of how good the instrument is at measuring low level signals, the lower this figure, the better, although the lowest signal level will still be governed by the measurement bandwidth. A typical spectrum analyzer may have a noise figure of 20 dB or more, whereas a typical receiver may have a noise figure of 10 dB. The preamplifier has a noise figure of typically 4 dB, significantly enhancing the low level performance of such instruments, enabling signals that were previously masked by noise to be seen.

Georg Fischer Signet
Pre-amplification is required to protect the output signal of pH and ORP electrodes from a wide variety of electromagnetic interferences common in industrial environments. Signet 2721 is used if remote pre-amplification is required (e.g. tank temperature >80oC) or connecting another manufacturer's electrode to the Signet 5700 or 8750 instrument. The Signet 2721 should be used with special order sensors built with cables (Signet models 277X-HT or 277X-1-HT).
