Highest possible performance
As official DRM supporter it is a
quite particular concern to us to promote the digital shortwave radio.
An important consideration in the
development of the DiRaWave 032 was therefore to process DRM signals optimally,
from the highest attainable signal-to-noise ratio (SNR) of the hardware to the
best possible implementation of DRM in the operating software.
Although for the DiRaBox 32 were
selected premium models with DRM-SNR performance >40dB already available upon
request, we were able to increase that value for the DiRaWave 032 by about 10dB
as standard. The DiRaWave 032 is thus an ideal choice for performance testing,
reference and measurement applications.
Best DRM performance: Direct
injection of a 9KHz DRM signal which is generated via SPARK-Transmitter and resulting
spectrum of about 50dB SNR+++
