Installation

Software requirements:

• Python 3.x
  • Requires Pyserial library
• FTDI VCP Driver

Front panel

Connectors:

• Drive+ Positive drive terminal
• Guard Guard voltage output, follows either Drive+ or Sense+
• Sense+ Positive terminal for 4-wire operation
• Sense- Negative terminal for 4-wire operation
• Drive- Negative drive terminal, all current flowing out from Drive+ must go into this terminal
• Ext Additional voltage input ( range: -2.5V .. 2.5V )

All SMA connector shields are connected to the system ground.

Operating principles

Strix uses a transimpendace amplifier to measure current so DUT must be floating.
