Introduction
The PASCO CI-7500 ScienceWorkshop ® 750
Interface, a data acquisition computer interface, is an
upgrade of the
ScienceWorkshop 700 Interface. It
performs all of the functions of the 700 Interface, and
includes the following improvements:
• analog samples up to 250,000 samples/second;
• rates through the SCSI port up to 4 times faster
than the 700;
• identical analog input channels—all differential
inputs, each with three gain settings: 1, 10, and
100;
• internal power amplifier for DC supply and wave
function generation up to 300 mA;
• 12 bits of AC amplitude precision, allowing
amplitude adjustments in steps of 2.4 mV;

• access to the analog output signal through banana
jacks, allowing output voltage and current to be
monitored without occupying one of the analog
input channels or requiring an external power
amplifer.
• greater accuracy with motion sensing events;
• AC wave frequency generation up to 50 KHz (10
times faster than the 700);
• automatic readjustments of analog input offset to
zero;
• upgradable firmware via flash ROM;
• option to operate through a serial port connection
when a SCSI port is not available.
Instructions for operating the ScienceWorkshop 700 in
the User’s Guide for ScienceWorkshop apply to
operation of the 750 Interface except for the items
detailed in this document.
