The new R-506 is designed for evaluation of signal coverage across a service area, analysis of signal
strength at a specific location, surveying sites for new antenna construction and making precise industry
required NIST traceable field strength measurements.

The R-506 in an excellent unit for those needing to characterize or maintain both analog and
digital RF wireless communications and Broadcast systems.

The R-506 expands the Z Technology product line of cost effective test instrumentation with a rugged,
portable unit designed for the professional user. This instrument is an excellent unit when precision, broad
band, highly portable field service tool is required.

The R-506 is a state-of-the-art instrument combining the functions of off-air field strength metering,
accurate RF signal strength measurement, and PC based automatic data collection and storage in one
convenient light weight system.

An operator can accurately measure signals at frequencies from 5 to 1000 MHz. The R-506 utilizes a
digitally encoded TUNE knob for front panel frequency selection. Step sizes available are 100, 10,
and 1 MHz, and 100, 10, and 1 kHz. The frequency of operation is continuously displayed while the digit
under control of the TUNE knob is highlighted. The system is fully synthesized and highly stable using
a precise TCXO crystal reference.

The R-506 accurately measures signals from -10 dBuV to +90 dBuV. The full dynamic range of
100 dB is available through a combination of the front panel controlled RF AMP and an internal
auto-ranging function. The RF AMP (internal preamp) is an integral part of the instrument. It
is preceded by one of a series of automatically selected internal RF Filters to minimize out-ofband
signal susceptibility. This allows measurement of weak signals while protecting against unwanted
strong signal overload.
