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.
