Hypatia Model 309

Hypatia's Model 309 is a high current sourcing milliohm meter. This instrument uses a Motorola 68HC16 microcontroller in conjunction with two very high precision 16 bit A/D converters for making measurements. True RMS voltage, current, & impedance values are output in real-time on the instrument's display as well as through the communications port. Control of the instrument settings (i.e. start/stop, timer setup, hi/low alarms, etc.) are provided by buttons on the instrument's front panel as well as by sending SCPI commands through the communications port.

A complete virtual instrument was developed to aid in automated test engineering applications using the SCPI commands. This virtual instrument was created in the form of a Windows™ ActiveX™ control. This allows developers to easily use the virtual instrument and add instrument control to their own custom applications.

This product's microcontroller circuit design, firmware (real-time embedded software), and the Windows™ ActiveX™ control were all developed by the principal engineer of Frank Design.
