The model DMB-1505 is a high-performance RF synthesized signal generator. It is designed to
convert signals generated by an OFDM signal generator into signals in the tuner reception
frequency Bands conformable to the European DAB (Digital Audio Broadcast) standards. It
covers the frequency Band Ⅱ(87.5 ~ 108MHz), Band Ⅲ(174 ~ 250MHz) and Band L(1452 ~
1492MHz), and controls output level in units of 0.1dB from 0dBm to -120dBm and the
frequency in units of 1Hz . Also, it is possible to store and recall 300 setting points and is
suited for developing and manufacturing of DAB system.
