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, FLEXTMand 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.
The wide IQ bandwidth allows the
generation of Direct Sequence Spread
Spectrum signals as used in CDMA as well
as QAM and OFDM signals as used in new
broadcasting formats such as DAB (Digital
Audio Broadcast).
Precision radar Chirp signals can be
simulated in conjunction with an Arbitrary
Waveform Generator to test radar
receivers.
Digital Modulation
In digital mode, the signal generator is
able to produce a wide array of digital
modulation types and in each case the
user is free to modify the data rate and
filter characteristics to suit individual
application needs. This level of control and
flexibility means that the 2050 series is
fully prepared today for the digital formats
of tomorrows narrow band digital radio
communications equipment.
For common standards, the 2050 is
already pre-programmed to generate the
required modulation format from a single
key press and so aid ease of use.
Proprietary schemes can be created and
stored into non volatile user memories.

pseudo random sequence generator or
supplied externally as a serial or parallel
data stream into a flexible digital interface.
A burst control input allows TDMA or TDD
bursts to be generated synchronously with
the data. A separate analog envelope
control input allows linear control of the RF
level to simulate bursted modulation
conforming to power time template and

adjacent channel spectrum requirements.
In digital mode the user can introduce
defined errors to the modulation as skew,
gain imbalance and carrier leakage, and so
aid investigation of design limitations.
Fading Simulation
The built-in Rician and Rayleigh fading
simulator with programmable path ratio
and Doppler speed allows testing of
receivers under real life propagation
conditions in which receivers must operate.
The availability of fading simulation at the
early design stages of new
communications equipment simplifies the
development of more robust designs and
reduces the time taken for full compliance
testing.
Software Assisted Calibration
All calibration and re-alignment
procedures can be carried out without
removal of the instrument covers and can
be performed either manually or
automatically via the GPIB. No internal
adjustments are necessary; even the
frequency standard is adjusted via the front
panel or GPIB. During manual alignment
full instructions are given on the instrument
display. In digital and vector modes a self
calibration system optimizes the
performance of the vector modulator; a
warning is displayed when environmental
changes or elapsed time warrant a recalibration of the modulator.
Electronic Attenuator
An electronic attenuator option is
available to meet demanding extended life
requirements for repetitive switching, found
in high volume production applications.

dot matrix display with softkey function selection
