Programmable Gain Amplifier

Raw data from the preamplifier MPA is amplified by the PGA amplifier with programmable gain. The PGA is a filter amplifier like the FA, but in addition, the gain can be flexibly adjusted from 10 to 5000 with the user-friendly program FiltAmp.

Standard versions with 16, 32, and 64 input and output channels are available under the name PGA16, PGA32, and PGA64, respectively.

The PGA1632 and the PGA3264 are special versions that feature two different pass bands. Signals are split and the two pass bands are send to two separate output channels. For 16 input and 32 output channels, or 32 input and 64 output channels, respectively. These amplifiers are perfect for recording signals with different frequencies. Amplifiers can be ordered with any bandwidth configurations by the user's choice. For example, typical pass bands would be 1-300 Hz for recording field potentials and 300-3000 Hz for recording action potentials.

It is also possible to use a broadband amplifier and filter the data with the digital filter of the free MC_Rack program.

Featruring two different pass bands

Raw data from 16/32 input channels from the preamplifier MPA is amplified by the PGA1632/PGA3264 amplifier with programmable gain. The gain can be flexibly adjusted from 10 to 5000 with the user-friendly program FiltAmp. The PGA1632/PGA3264 features two different pass bands. Signals are split and the two pass bands are send to two separate channels, which gives you 32/64 output channels in total. These amplifiers are perfect for recording signals with different frequencies. Amplifiers can be ordered with any bandwidth configurations by the user's choice. For example, typical pass bands would be 1-300 Hz for recording field potentials and 300-3000 Hz for recording action potentials.

FiltAmp-Software

Print and load your gain settings
With the user friendly program FiltAmp, the gain of a PGA can be flexibly adjusted from 10 to 5000 for all channels separately. Simply pick the desired gain from the drop-down list. Download the settings on the PGA amplifier via the serial port and you are ready to go. You can print a report and save the gain configuration for later use.
