The DEX PCB Designer Spice Probe

Oscilloscopes

This is a 4 channel oscilloscope that show the signal that the terminal is connect to. You can have as many oscilloscopes as you want in your design.

Signal Generators

This is a function generator that can add sin, triangle, sawtooth, reverse sawtooth or square signals by adding 2 wires from it's terminals to wires in your design.

Charts

This is a 4 channel oscilloscope with the extra graphics removed that show the signal that the terminal is connect to. You can have as many oscilloscopes as you want in your design.

Power Supplies

This is a single output power supply. Simply connect wires from the output to wires in your circuit. You can add as many as you want to your design.

Devices

You can add all the XSpice part models you like using the Part's Property Panel.
