Internally generate /4 DQPSK, GMSK, GFSK, signals to meet the test requirements of NADC, PDC, PHS, TETRA, GSM, and DECT receivers with Options UN3/UN4. Test CDMA mobile components and enable transmitter tests by generating QPSK and OQPSK signals with Option H03. A choice of internal or external data generation, and flexible framing and time-slot configuration capabilities is available. In addition, adjustable data rates, filter factors, and burst shaping provides operators enormous measurement versatility.
Easily configure timeslots to simulate different types of traffic, control, or synchronization channels (or bursts). Generate mobile- or base-station transmissions for a variety of digital communications standards with the internal burst capabilities. Also, reduce the need for external equipment with comprehensive data generation capabilities.
Use the analog I and Q inputs to generate the complex modulation formats (such as BPSK, QPSK, and 16QAM), required for the development and testing of RF digital communications systems. A built-in quadrature modulator processes the I and Q input signals to provide superior modulation accuracy and stability over a 10 MHz (1 dB) bandwidth.
Make sensitivity tests accurately and efficiently with the wide power range (+13 to 136 dBm) and superior level accuracy of the HP ESG-D series RF signal generators. Level accuracies of better than +/-1.1 dB for the built-in modulation formats and typically less than +/-0.6 dB, ensures precise measurement of even the most sensitive digital receivers.
Extremely stable dc FM precisely reproduces digital signaling for FM receivers with selective squelch control. Wideband phase modulation capabilities are useful for satellite communications applications, offering deviations up to 90 radians and 6 MHz rates.
