The AC-coupled preamplifier J2180A with a fixed gain of 20 dB is characterized by particularly low noise. The bandwidth of this amplifier ranges from 0.1 Hz to 100 MHz (3 dB point). The input resistance is 1 MΩ, its output resistance is 50 Ω. With this data, he can improve the sensitivity of oscilloscopes, network and spectrum analyzers by reducing noise and spikes. This preamplifier can also function as a DC block for low-frequency signals or it can be used for a high-ohm probe on a measuring device with a 50 Ω input.
The J2180A preamplifier offers very low noise, low distortion and a slope of 100 V / µs for pulse and audio applications.
