PZ3 Low Impedance Amplifier
connectors on the PZ3 back panel. A break out box or connector(s) are required
for electrode connection.
TDT provides a version of our LI-CONN connector for the PZ3: the LI-CONN-Z for
Shared Differential mode. It features standard 1.5 mm safety connectors and provides
easy connections between electrodes and the amplifier.
Hardware Set‐up
The diagram below illustrates the connections necessary for PZ3 amplifier operation.
One or more male connectors (such as the LI-CONN-Z) can be connected to the
input connectors on the PZ3 back panel. Alternately, custom connectors and a
breakout box can be used. If using custom connectors, see “Input Connectors” on
page 7-76 for pinout.
Note:
In Shared Differential mode no connection should be made to the indifferrent (-)
channels.
A 5 meter paired fiber optic cable is included to connect the preamp to the base
station. The connectors are color coded and keyed to ensure proper connections.
The PZ3 battery charger connects to the round female connector located on the back
panel of the PZ3 amplifier.
Important!
To avoid introducing EMF noise, DO NOT connect the charger to the PZ3 while
collecting data.
PZ3 Software Control
The amplifier’s mode of operation (shared or individual differential), other options,
and channel mapping tasks are handled using PZ3 specific macros within the
RPvdsEx control circuits running on the RZ2 Signal Processor.
RPvdsEx includes two PZ3 specific macros:
PZ3_Control macro
PZ3_ChanMap macro
