Tech Note 162 Detail

Comparison to 700

Affected Products:

CI-7565 ScienceWorkshop 750 Interface

Problem/Symptom:
What are the differences between a 750 interface and a 700 interface?

PASCO Solution:
The 750 interface 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 amplifier
  • 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
  • upgrade firmware via flash ROM
  • option to operate through a serial port connection when a SCSI port is not available
