Krohn-Hite Model 7008 Preamplifier 8-channel

Model：Model7008      Country of Origin：USA      Category：Ultra-Low Noise Preamplifier

Overview：Krohn-Hite's Model 7008 is an eight-channel, remotely programmable, differential preamplifier featuring low noise and high gain, capable of amplification up to 1MHz. The 7008 uses an extremely low-noise FET instrumentation amplifier as its output. Input noise is 7nV/√Hz, and common-mode rejection is greater than 100dB at 1kHz. The 7008 has fixed gain settings of 1 (0dB), 10 (20dB), 100 (40dB), and 1000 (60dB)...
