Enhanced Design Features - Radian RD-30 Operation Manual

Product Intoduction
The RD-30 also provides a serial communications port which allows direct connection to the RS-
232 serial port of a personal computer. RD-30s with the Built-in Computer option come with RR-
MobileSuite software.
The RD-30 is available in a variety of models offering measurement functions and options to suit
specific needs.
1.1 Enhanced Design Features
Many design features have been added or improved through the engineering process of designing
the RD-30 Dytronic. The addition of A/D and DSP technology, increased PC support and an
enhanced version of Radian's revolutionary voltage and current transformer input design make
the RD-30 the benchmark of portable standards, second only to the RD-31 portable threephase
reference standard. The RD-30 utilizes Radian Research designed Analog/Digital circuitry
coupled with Digital Signal Processing techniques. These advancements provide a high degree
of flexibility including simultaneous multifunction measurements and harmonics analysis
capabilities.
A/D and DSP Technology
In order to accelerate the testing process, Radian Research has designed and incorporated a
custom integrating Analog to Digital Converter into the RD-30. There are separate A/D circuits
for both the voltage and current axes. Couple this enhancement with the utilization of DSP
technology and the RD-30's abilities are greatly enhanced. The RD-30 can effortlessly collect
the converted digital signals from the A/D converters and process the data to display every
measurement function supported during a single collection of voltage and current data.
PC Support
For enhanced analysis and testing, each RD-30 is equipped with a communications port. This
port will allow the user to connect to a personal computer running Radian Research software
packages providing for customization of the standard. Different configurations containing input
and output port designations, LCD menu operation and other parameters may be stored in RR-
PCSuite software and downloaded to any RD-30 unit for complete user customization.
