Description
A-M Systems is proud to introduce our new Model 3500 16-Channel Extracellular Differential AC Amplifier.
In response to many inquiries for a larger version of our popular Model 1700 4-Channel Differential AC Amplifier, we have developed this unit. The Model 3500 has 16 independent channels, a front panel touch screen, computer control capabilities and a built-in calibrator. In addition, users can quickly monitor on an external oscilloscope the activity on any two channels.Multiple instruments will be controllable by a single computer program, enabling the setting of critical parameters on as many channels as you need.
Compared to the Model 1700, the Model 3500 has:
- More gain settings and increased gain range
- More high pass filter settings and increased high pass range
- More low pass filter settings and increased low pass range
- TTL Control of instrument mode
- Twin stimulation busses to pass current
- Channel Monitors
- Built-In Calibration signal
- Common Reference Bus
- Blanking
- PC control capability
- MATLAB® and LabVIEW SDK and drivers available
- Less rack space utilized for 16 channels
