2300 Signal Conditioning Amplifier System

The 2300 is a sophisticated multi-channel signal-conditioning amplifier for exacting instrumentation tasks. Advanced features include an individual regulated power supply for each channel, active filtering selectable by push-button control, three simultaneous outputs per channel, playback operating mode, wide frequency response, and automatic electronic bridge balance.

Features

• Selectable bridge excitation, 0.5 to 15 Vdc
• Fully adjustable calibrated gain from 1 to 11 000.
• Dual-range ( 5000 and 25 000 microstrain) automatic bridge balance
• “Keep-alive” power to preserve balance for months without external power
• Built in, bridge completion including 120- or 1000- and 350-ohm dummies
• Dual polarity two-step double shunt calibration
• Bandpass of 50 kHz (-0.5 dB) to 125 kHz (-3.0 dB)
• Switchable active filter – up to six poles
• Three simultaneous buffered outputs
• Input impedance above 10 megohms at all times
