Type

Krohn-Hite 's Model 7008 is an eight-channel, remotely programmable,

Differential preamplifier featuring low noise and high gain, capable of amplifying 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 1 (0dB), 10 (20dB), 100 (40dB)

and 1000 (60dB). Four input configurations available for current-to-voltage conversion

and four-input shunt resistor options.

16 bytes, dual-line front panel as a display to show each channel's configuration

integrity. Optional USB or LAN for remote programming of all parameters. BNC con-

The connector provides single-ended and differential input configurations, as well as amplified output.

The 7008 has an extremely wide range of applications, such as amplification when noise is present in data acquisition systems

low-level signals, temperature measurement, audio engineering, radio astronomy, optical detection,

process control, and as a general-purpose preamplifier for other equipment.

Selectable input configuration: differential, +SE, -SE and OFF

Optional input shunt resistor: 50, 500, 5k and 50k ohms

Common-mode rejection ratio: >100dB at 1kHz 

Optional remote programming: USB or LAN
