The Warner DP-314 is a four channel AC/DC amplifier with differential pre-amplifiers having active input headstages highly suited for EEG, EKG, and extracellular recording.
The DP-314 employs 'active headstage technology' that performs the differential measurement within the shielded headstage. The common mode rejected signal is then sent to the main amplifier for high gain amplification. This allows the DP-314 to provide a lower noise output when compared to other instruments that send undifferentiated signals to the amplifier for remote common mode processing.
High common mode rejection is very important in minimizing electrical interference. The high input resistance of the DP-314 (1012 Ω typical) ensures that the instrument's high CMR will not be degraded by differences in source impedance. This is important for extracellular recording where the difference in resistance between the recording and indifferent electrode is often very large.
Extracellular action potentials are typically measured in microvolts but are usually accompanied by much larger DC electrode voltages. The DP-314 is designed to amplify these µV level events with as much as ±10 VDC at the input.
With gain selections at x10, x100, x1000 and x10,000, even µV signals are sufficiently amplified for computer and recorder inputs. Noise is very low, typically 10 µV p-p at 1 Hz to 10 kHz bandwidth. Reducing the bandwidth with the low pass and high pass filters can further lower the noise.
An internal Cal signal provides a convenient check of amplifier gain and operation.
