Description

The Digitimer D440 Isolated EMG Amplifier is a low noise solution for human EMG studies, specifically those related to nerve excitability. Low noise performance is significantly enhanced through the use of a Driven Right Leg (DRL) circuit which reduces Common-mode interference.

The D440 features an amplification range of ×100 to ×20k. The gain, filter and mode settings for individual channels are adjusted using Digitimer’s “virtual front panel” software or other software via a COM interface.

The D440 is available in two versions, the D440-2 (two channels) and the D440-4 (four channels). Each channel features a pair of 1.5 mm touch proof sockets for active and reference electrode connection, but provision is also made for shielded leads with 5-pin DIN connectors. Each amplifier is supplied with a signal output cable (D440-OL-xx, D connector to multiple BNC), electrode connection cable (D-440-IL, 1.2m long with 3 × 1.5 mm DIN42802 sockets for electrode connection and 270 degree 5-pin DIN plug for amplifier connection) and USB cable for connection to the host computer.
