The PA-01GX is designed to amplify small bio-electrical signals. One output with two inputs is available, which can be used in AC or DC mode. The two inputs can be added or subtracted before amplification. DC offset can be compensated either by using the OFFSET control with two ranges, or by using the AC position of the input switches. Inputs and output are BNC connectors.
Input and output configurations are selectable. The PA-01GX can be connected internally to other modules of the EPMS-07 system, e.g. to one channel of an EXT-08, to a DPA-2F or to an INT-20M module. Both INPUT and OUTPUT signals can be linked internally to other EPMS modules. Two LEDs indicate when the linear region of the amplifier (± 10V) is exceeded.
The input impedance is 1 MΩ (other impedances are available on request). The GAIN range is x1 to x5000 and can be set by a rotary switch.
