Bode Plotter
The Bode Plotter is VNA (Vector Network Analyzer)
software that operates the CircuitGear hardware over the
frequency range 0.1 Hz to 3 MHz to measure amplitude and
phase for circuit theory and filter design exercises.

Software
The oscilloscope, generator, and digital I/O are operated
from a software GUI (graphic user interface) included with the hardware. The
software is open-source and source code is included. The software is
written in Tcl/Tk, a scripting language that is easy to
learn yet powerful for creating GUIs. It runs under Windows,
Linux, Unix, and Mac operating systems.
CircuitGear is compatible
with National Instruments LabVIEW, MATLAB, Visual Basic, and
any application or programming language which can access
serial ports. Syscomp provides LabVIEW example VIs that
demonstrate how to control CircuitGear. Screen shots of the
LabVIEW examples are shown below. The LabVIEW examples are
available on the
download
page.
