More Information

Ametek / EG&G / Princeton Applied Research 181 Current Sensitive Preamplifier Overview

Features:

  • Low Input Impedance
  • Low Noise
  • Wide Range of Gain Settings
  • High Open Loop Gain
The Ametek / EG&G / Princeton Applied Research 181 Current Sensitive Preamplifier offers lower internal noise, greater frequency response, higher dynamic range, greater phase accuracy and lower input impedance than nearly any other low-level ac current-measuring system manufactured. In photometric applications, the system's low internal noise enables you to utilize fully photodetectors with dark currents as low as 10-4A/V Hz. The system's wide frequency response enables you to employ high chopping rates to minimize the effects of 1/f noise and power-line pickup. The system's high dynamic range enables the user to measure small ac currents superimposed on quiescent detector current as great as 10 times the current-to-voltage conversion setting without overloading the preamplifier. In semiconductor applications, the low input impedance enables the user to plot accurately the actual bias voltage applied to the device under test without having to worry about the effects of back bias. The system's low internal noise enables the user to measure accurately the smallest capacitance changes without having to use excessively long time-constants. The system's low phase shift enables the user to take data at several different frequencies without having to readjust controls continually. This combination of performance features makes the 181/EG&G PARC Lock-In Amplifier combination the ideal choice for many applications involving the measurement of minute ac currents.

A 600Ω output is manufactured at a rear-panel BNC connector to permit monitoring of the input signal.

The Ametek / EG&G / Princeton Applied Research 181 provides 10:1 attenuation of output voltage.

The EG&G 181 Current Sensitive Preamplifier may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).

Current Sensitive Preamplifier Price & Specs

Ametek / EG&G / Princeton Applied Research 181 Current Sensitive Preamplifier Description

Ametek Model 181 Current Sensitive Preamplifier is engineered for high-performance amplification of low-level current signals in demanding scientific and industrial applications. This specialized instrument, often found in setups by legacy brands like EG&G and Princeton Applied Research, provides a crucial interface for converting weak current outputs from various sensors and detectors into measurable voltage signals, enabling precise data acquisition. It plays a vital role in experimental physics, chemistry, and other research areas requiring sensitive current measurement. The Model 181 is designed to integrate seamlessly into complex measurement systems, enhancing the detection capabilities of downstream instrumentation. Its architecture provides a stable platform for amplifying extremely small currents, essential for applications where signal integrity is paramount. This preamplifier facilitates accurate current-to-voltage conversion in setups requiring high input impedance and low noise performance.

Functions

Low-noise, low-input-impedance transimpedance preamplifier converting extremely low detector or device currents to voltage with selectable sensitivities from 104 to 10? V/A, DC to ~200 kHz bandwidth, and single-ended virtual-ground input with adjustable negative bias for photodiodes or semiconductor devices. Provides high dynamic range for small AC signals in presence of large DC currents, main and monitor outputs for connection to lock-in amplifiers or measurement instruments, and operates from ±15/±24 V supplies in bench or system environments.
