Anritsu   The MN3650A Digital Modulators provide Pi/4 DQPSK and GMSK modulated signals in the 800 to 2700 Mhz frequency range. Can use either external data signals or I, Q signals to perform modulation. Accepts burst signal. Furthermore, by using the additional Option 01 Burst Function, these units can be used with addition TDMA system. The rise/fall time of burst signal waveform are moderate, that are equal to two symbols, adjacent channel leakage power measurement can be done as a continuous wave. These models are ideal for developing systems such as the GSM, NADC, PCN, PDC and PHS.Features: * Provides Pi/4 DQPSK and GMSK modulated signals * 800 to 2700 MHz frequency range * Low phase-noise may be used as an RF signal source to output high-accuracy, phase-modulated signals with a phase error of 2 rms max. * (GMSK modulation) or a vector error of 1.5% rms max. (Pi/4 DQPSK modulation) * Can be used with additional TDMA systems * Rise/fall time of burst signal waveforms are moderate, an
