BNC to BNC Cable
Our BNC-to-BNC Coaxial Cables come in a variety of lengths, from 6 inches to 10 feet, and work well with our electrophysiology equipment and meters. These cables have a metal, male BNC connector on both ends of the cable. BNC (Bayonet Neill-Concelmen) connectors have a bayonet-style locking mechanism that provides a secure connection. These coaxial cables have an impedance of 50 ohms (RG58U style). The cables have excellent shielding from electromagnetic interference and radio frequency interference, which is perfect for electrophysiology laboratories. The length of your cable can affect the signal quality, so choose the shortest cable that is long enough for your application. Learn More

Linear Stimulus Isolator
Model A395 generates a user-defined output current of wave shape; DC, AC, pulse and combinations. Battery operated, photoelectrically-isolated from the input voltage drive, the instrument regenerates output currents which are linearly proportional to the analog voltage waveforms provided by your D/A converter or signal generator.

Dummy Load Resistor Kit
A365 can be used as a precise voltage source by placing a precision “dummy” resistor load across the output terminals. Precision resistors (such as the 100 Ω, 1000 Ω and 10,000 Ω resistors in WPI’s optional Dummy Load Resistor Kit #DRL) when placed across the output terminals convert the precision current levels to accurate voltage levels.
For example, 1 milliampere flowing through 1000 Ohms will produce 1 volt across the output terminal pair. Thus, models A365D and A365R can be used as low noise sources of accurate voltage pulses or DC. To maintain less than 1% error, avoid shunting the output dummy resistor with a load resistance less than 100 times the dummy resistance value.
