2.1 Welcome to the R&S EDST300
The R&S EDST300 is an analyzer designed for installing, testing and servicing pulsed
terrestrial navigation systems like DME and TACAN ground equipment. Its wide
dynamic range and compact design make the R&S EDST300 ideal especially for wired
and field measurements on DME and TACAN ground stations.
The R&S EDST300 provides high-precision stimulus and analysis functions for DME /
TACAN signals in the frequency range from 960 MHz to 1215 MHz. It performs TX/RX
measurements required for DME und TACAN ground stations in line with the relevant
civil and military standards accurately and efficiently.
The R&S EDST300 can precisely determine characteristic parameters such as peak
power, main delay, reply efficiency, and can decode the identifier of the ground station
to be tested. The instrument also measures the parameters of TACAN stations
(R&S EDST-K1 option) and performs in-depth pulse analysis (R&S®EDST-K2 option).
The modular design of the R&S EDST300 provides a high degree of flexibility to adapt
it to the task at hand. An interrogator (R&S EDST-B2 option) with adjustable output
power (-80 dBm to +30 dBm peak power) is available for RX measurements. An internal battery (R&S EDST-B3 option) and a test antenna (R&S EDST-Z1 option) deliver
maximum flexibility when carrying out field measurements. Measured data can be
exported to a control system via remote control (LAN), or stored on a USB flash drive.
