2-4 An Introduction to WavePort 09-29-00 WavePort User’s Manual
WavePort/PE8
WavePort/PE8 can measure up to eight channels of voltages within ±10V; and up to 8 channels of ICP ® transducer excitation.
The unit receives its channel-input signals through two columns of eight BNC connectors (16 channel inputs total). The
columns are labeled MODULE 1 and WAVEBOOK. In addition to the channel-input BNCs, WAVEBOOK contains a BNC
for PULSE Trigger Input, and MODULE 1 include one BNCs for filter clock input (FILTER CLK. IN), and another BNC for
EXCITATION SOURCE OUT (see following figure).
The signal panel includes a DB25 connector for DIGITAL I/O, EXT CLOCK (external clock), and TTL TRIGGER.
Connection nodes for CHASSIS (ground) and ANALOG COMMON are also provided.
