This picture shows the BIB upside down. The 9-pin D connector shown on the left is for inputs from sonic ranger, shaft encoder, strain gauge etc. DIN connector on the right. The software runs a test to establish a maximum sampling rate, which is below 1 kHz on 8088 PCs, somewhat below 10 kHz on 386 PCs, and is near 15 kHz for pentium PCs. The BIB has an on-board amplifier with an adjustable gain of up to 500 or so.
Several programs permit combined sensor input.
For example, at Rose we now obtain data from single and double slit diffraction by making one pass with the detector. The light detector for this experiment is connected to a shaft encoder so that as the detector is moved through the pattern, the encoder is turning and records the position in addition to the photo-voltage. Then the user presses a key and strain gauge data is taken during the collision, After the collision sonic ranger data is resumed, giving the user initial and final velocities as well as details of the force vs time during the collision itself. The 1994 software was DOS-based. With the advent of Windows 95, Rose has developed a W95-compatible set of programs.
