Wideband Differential DC Amplifier Ectron Model 751
Precision
Wideband Differential DC Amplifier Ectron Model 751 is
a Precision Wideband DC Amplifier, featuring true differential
input circuits, high-common-mode- voltage rating and excellent
stability and linearity.
The basic Precision Wideband Differential DC Amplifier
Ectron Model 751 is a direct-coupled design providing
high input impedance, excellent common-mode-rejection
and low output noise.
Each Precision Wideband Differential DC Amplifier Ectron
Model 751 has its own independent internal power supply
which operates directly from standard 50 to 400 Hz power
lines.
Amplifier gain is front-panel selectable from x0.01 to
x1,000 with gain accuracy of ±0.01%.
Precision Wideband Differential DC Amplifier Ectron Model
751 bandwidth is front panel selectable with 3-pole low
pass filters having -3 dB cut-offs of 1 Hz, 10 Hz, 100
Hz, 1 kHz and 10 kHz plus a wide band setting. Full bandwidth
exceeds 100 kHz.
Performance Highlights:
• 300 V Common-mode Voltage (CMV)
