| State-of-the-art amplifiers that fit your needs |
| With asa-lab ERP you can select the best amplifier for your application. Whether you are looking for interested in cognitive ERPs or short-latency EP components, ANT has the amplifier that fits your needs! |
Full-band DC amplifiers The high-density amplifiers allow you to record data up to 128 channels, or even more in case amplifiers are combined. Connect the amplifier to the USB of your notebook for a portable system. This in combination with our innovative WaveGuard cap system provides with all the power you need for those studies. A high-speed amplifier is available for those cases were you need the high sampling rate. The amplifiers can record up to 10kHz for 32 channels and up to 5kHz for 64 channels. |  |

High-density amplifier Number of channels 32, 64, 128 and 256 Sampling frequency 256, 512, 1024 and 2048 Hz (maximum 1024 Hz for 256ch) Resolution 22 bit, 71.5 nV per bit Input impedance > 10^12 Ohm Noise < 1.5 microVpp (at 100 Hz) CMRR > 110 dB Trigger input 8-bits TTL Connection to PC Fiber optic to PCI card or USB2 | High-speed amplifier Number of channels 16, 32 and 64 Sampling frequency 10,000 Hz for 16 and 32ch; 4000 Hz for 64ch Resolution 24 bit, 29.8 nV per bit Input impedance > 10^12 Ohm Noise < 1.0 microVpp (at 0.8 - 500 Hz) CMRR > 110 dB Trigger input 8-bits TTL Connection to PC Fiber optic to PCI card or USB2 | |||
Active-noise cancellation The electrode inputs are shielded with the electrode signal itself (active shielding). This ensures a disturbance free measurement and has the effect that 50/60Hz interference and artifacts due to movement of cables are reduced to a minimum. |
Bipolar and auxiliary (high level) inputs Bipolar inputs are available on the high-density type amplifiers and allow the recording of EMG, EOG, ECG etc. using a true hardwired bipolar channels. The bipolar inputs are actively shielded.Auxiliary inputs can be used to connect active sensors like respiration bands, GSR, nasal flow sensors, pH sensors etc. to the amplifier. Each auxiliary channel has a 5-pin connector. Signals on this connector are power (+5V,-5V), ground, and +signal and -signal input (actively shielded). |
fMRI, MEG and TMS compatibility The asa-lab high-definition amplifiers are fMRI, MEG and TMS compatible. A non-magnetic battery pack powers the amplifiers during acquisition (up to 8 hours). MEG/EEG or fMRI/EEG acquisition is carried out using a special designed non-magnetic cap. |
Cascade amplifiers for more channels! Both high-density and high-speed amplifiers can be cascaded for those cases when you need more channels. Cascading of amplifiers is achieved by connected two amplifiers of the same type to one computer. The asa recording software takes care of the rest! |  |
