For the very latest specifications visit www.aeroflex.com Designed to meet the needs of modern digital radio technologies up to 5.4 GHz Signal Sources 2050 Series Digital & Vector Signal Generator • PSK, FSK, QAM, GMSK • I and Q modulation to 10 MHz (1 dB bw.) • External digital data input • Internal PRBS data source • Excellent accuracy and stability • Envelope control for RF bursts • Programmable channel filter characteristics • Variable data rate control • NADC, PDC, GSM, TETRA plus others • Wide band DCFM for fast FSK • Baseband I & Q outputs • Electronic attenuator option The 2050 series of digital and vector signal generators covers the frequency range 10 kHz to 1.35 GHz (2050), 10 kHz to 2.7 GHz (2051) and 10 kHz to 5.4 GHz (2052). These instruments are suitable for a wide range of applications including the testing of new digital communication systems. Modulation Capability The 2050 combines comprehensive analog modes, AM, FM, PM and Pulse (optional), with I Q vector modulation. A digital mode using internal DSP (digital signal processing) is provided to convert digital data into complex modulation formats as shown in the following table. FSK 2 and 4 level GMSK PSK 2, 4 and 8 level DPSK (Differential) 2, 4 and 8 level Phase Offset DPSK 2, 4 and 8 level Time Offset PSK 4 level QAM 4, 16, 64 and 256 level Two FM modes are available, wideband FM (>10 MHz) for fast FSK or video applications and a 1 MHz bandwidth mode. Both modes offer FM deviations up to 1% of carrier frequency. FM is available as either DC or AC coupled. A patented FM nulling correction system eliminates carrier frequency offsets that occur with lesser generators when using DCFM, and allows the 2050 to be used confidently with Wireless LAN or paging equipment such as POCSAG, FLEXTM and ERMES. Vector Modulation In Vector mode the signal generator accepts I and Q modulation inputs with 10 MHz, 1 dB bandwidth. This precision modulator enables any modulation characteristic to be simulated with a high degree of accuracy, typical vector errors of less than 0.5% are possible. The excellent temperature stability and drift characteristics of the modulator ensure calibrated signals are always available making this the ideal choice for demanding research and development applications as well as in manufacturing of digital communications systems.
