Signal Aspects, WavePort/PE16
WavePort/PE16 can measure up to eight channels of voltages within ±10V and up to 16 channels of ICP ® transducer
excitation. WavePort/PE16 receives its channel-input signals through three columns of eight BNC connectors (24 channel
inputs total). The columns are labeled MODULE 2, MODULE 1, and WAVEBOOK. In addition to the channel-input BNCs,
WAVEBOOK contains a BNC for PULSE Trigger Input, and the two MODULEs include BNCs for filter clock input
(FILTER CLK. IN), and 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.
