獨立電壓/電流輔助刺激器 Digital Stimulus Isolator

產品型號: 2300
廠牌名稱: A-M Systems
Model 2300獨立電流輔助刺激器為一款功能功能基本且易於操作的雙極電刺激器,此刺激器可使用9V電池進行電刺激,無需外接電源,可大量降低交流電刺激所產生的大量雜訊。

產品特點

The Model 2300 Digital Stimulus Isolator provides opto-electrical isolation and amplitude control for square pulses whose timing parameters are generated by your computer. These levels are set by the front-panel ten-turn potentiometers. Scaled according to the Range switch setting, these levels can result in an output up to 50 V or 5 mA.

The Model 2300 can generate monophasic or biphasic pulses when provided with three TTL control signals: On/Off, Baseline/Pulse, and Polarity.

  • “On/Off” determines if the Model 2300 output section is enabled.
  • Baseline/Pulse determines if the front panel Baseline potentiometer or if the front panel Pulse setting determines the output level.
  • Polarity determines if the output is positive or negative.

By strategically controlling the values of these three TTL control signals, you can control the pulse timing and the output parameters.

If for any reason the instrument cannot follow the input signal, an Error indicator lights. The isolated output section is battery-powered and optically-coupled to the input section, for complete signal isolation.

The battery is adequate to provide full function for at least 8 hours of continuous use. An internal battery tester is provided. A charger is supplied, and an overnight charge cycle is all that is required to ready the 2300 for another day’s use.
