- summary: <p>The <strong>Picotest J2181A is a high-performance, low noise preamplifier</strong> designed for professional electronic engineers. This versatile device provides a fixed, AC-coupled 60dB gain while converting a 1 MOhm input impedance to a 50 Ohm output impedance. With a 3dB bandwidth of 10Hz to 1MHz, the J2181A significantly enhances the sensitivity of oscilloscopes, network analysers, and spectrum analysers.</p>
<p>Featuring wrap-around high-permeability shielding, the J2181A reduces susceptibility to ambient noise, making it ideal for ultra-low noise measurements. Its fast 100V/µS slew rate enables precise analysis of PLL, LNA, ADC power rails, and ultra-low noise voltage references and regulators. The integrated bi-directional DC-Block (6.3V) allows for seamless connection between high-input impedance oscilloscope probes and 50 Ohm equipment.</p>
<p>With a typical noise of just 1.5nV/√Hz, the J2181A is an essential tool for engineers requiring high-precision measurements in low-noise environments. Its compatibility with near-field probes for EMI troubleshooting and the P2106A probe for ultra-low noise measurement up to 2MHz further extends its versatility in professional electronic design applications.</p>
