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
specic 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 exibility 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 congurations 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.
