Up to three fully functional signal generators in one unit offering a unique solution for complex tests
on receivers, components and systems.
Signal Sources
2026A/B 10 kHz to 2.05/2.51 GHz MultiSource Generator
Two or three high quality RF signal gener­ators in a space efficient format
Wide frequency coverage:­10 kHz to 2.05 GHz (2026A) 10 kHz to 2.51 GHz (2026B)
+24 dBm RF output for effective compo­nent testing
Support for an external signal generator
Application specific test modes simplify measurement procedures
User defined tracking between signal sources
Adjustable carrier phase to allow peaking of three tone intermodulation
Built-in switched combiner network improves measurement uncertainty
Optional GSM modulation for testing multi-carrier power amplifiers
Optional Bluetooth and GSM modulation
The 2026A/B are multiple source generators which offer two RF signal generators in one box with a third source available as an option. Each source is a fully functional RF signal generator with AM, FM, ØM, 2FSK, 4FSK and pulse modu­lation capability.
The 2026A/B are ideal for use in R&D and manufacturing where there is a need for two or three combined sources for conduct­ing tests such as intermodulation and selectivity performance of components and receiver assemblies.
To aid the user to undertake difficult test procedures simply and without ambiguity, the 2026A/B family provide application-spe­cific modes of operation. Application modes include amplifier two and three-tone intermodulation, receiver intermodulation and receiver selectivity. A rotary control and up/down keys allow easy modification of the selected parameters.
Measurement Accuracy
The use of a built in combiner, switches and cables eliminates many of the measurement uncertainties introduced by connect­ing together separate signal generators. The 2026A/B family thereby guarantees the level of intermodulation products intro­duced during amplifier or receiver intermodulation testing.
All alignment processes, including the internal frequency stan­dard and the correction factors for the signal source RF paths, are digitally derived so realignment can be undertaken without removal of external covers. Digital adjustment also eliminates the use of mechanical adjusters, minimizing long term drift and vulnerability to mechanical shock.
Application Modes
The 2026A/B family has a Set Up Key to enable the applications to be selected. Each Set Up is displayed as a pictorial represen­tation of the internal signal source routing. A spectral diagram is used to show the parameters to be entered in each application in well known engineering terminology.
Spectral diagram of two tone intermodulation on a receiver
For example, selecting ‘Intermodulation on a Receiver Test’ allows the signal sources to be automatically set by entering the receiv­er input frequency and level, the ratio of the level of the two inter­ferers (relative to the receiver input level) and the offset frequen­cy (channel spacing).
Application mode for intermodulation test on a receiver
Other application modes include 2 and 3 tone inter modula tion tests on amplifiers and receiver selectivity.
Flexible Source Routing
Each of the signal sources can either be routed to a separate out­put connector or switched to the input of an RF combiner network before being fed to the combiner output connector.
The combiner routing is set up quickly and effectively using the Combiner Set Up menu. The flexibility of the signal routing allows the 2026A/B family to accept an external signal generator, such as the 2050 Digital and Vector Generator, to enable different forms of carrier signals to be produced. Alternatively the output from a 2029 Vector Modulator, driven from one of the 2026A/B sources can be routed in.
Setting up the source and combiner routing
Automatic Source Coupling
As an alternative to the application modes, the 2026A/B MultiSource Generator family allows the frequency and level of the internal RF sources to be coupled together with a user defined offset.
The source frequencies can have an offset with an additional har­monic (or sub-harmonic) relationship to simplify the testing of har­monic converters and divider systems.
The coupling factors are entered by an easily understood format using a dedicated coupling menu.
Setting up coupling
The ability to set sources to track each other greatly simplifies the testing of mixers, multipliers and dividers by reducing the number of active controls required.
Sweep
The 2026A/B family allows one of the RF sources to be frequen­cy swept with user defined start, stop, and step values to reduce the amount of operator time or GPIB overhead. By enabling the coupling facility, sweeping one source will simultaneously sweep the other internal RF sources to allow automated swept measure­ments on frequency conversion devices to be made.
The sweep can be performed with modulation enabled for swept measurements of receiver immunity characteristics.
2026A/B sweep menu
High RF Output
The high RF level of the individual outputs is ideal for testing com­ponents and ensures that the 2026A/B family can generate high RF levels at the combiner output while maintaining low levels of intermodulation.
Comprehensive Modulation
Each signal source is capable of being independently modulated from its own fully programmable modulation source to ensure maximum flexibility. The internal modulation sources are each capable of generating sine, triangle or square wave signals.
Amplitude, frequency and phase modulated carriers can be gen­erated from the internal modulation sources or from the inde­pendent external inputs. The frequency modulation system pro­vides excellent performance in the DC coupled mode with very

low carrier frequency error and stability ensuring that the genera­tor can accurately test receivers sensitive to small frequency errors.
Pulse Modulation
Each source is capable of being independently pulse modulated to allow the simulation of TDD or TDMA RF signal bursts with pulse on/off ratios of better than 40 dB and a rise time of less than 10 µs.
FSK
In addition to the analog FM facilities, the 2026A/B MultiSource Generator family supports 2 and 4-level FSK signals from external logic inputs. The FM deviation generated is set by keyboard entry of the required deviation. The facility is ideal for testing paging receivers and RF modems.
GSM Modulation
Option 116 is available to allow 2026A/B to emulate GSM signals using FM techniques which achieve superior noise floor perform­ance than solutions using IQ systems.
The facility is ideal for testing GSM receiver selectivity and for test­ing the linearity of high performance multi-carrier power ampli­fiers.
HIGH SPECTRAL PURITY
Typical SSB Phase Noise at 1 GHz
Typical Phase Noise at 20 kHz offset
Measurement of receiver selectivity and ultimate signal-to-noise ratio requires good spectral purity. The 2026A/B family has a low residual FM of typically 3 Hz and typical sideband noise of
-121 dBc/Hz at 20 kHz offset from 1 GHz, to allow demanding measurements to be made.
Programming
A GPIB interface is fitted so that all standard signal generator func-
tions are controllable over the bus. The protocol and syntax of GPIB commands has been designed in accordance with IEEE
488.2 standard to facilitate the generation of ATE programs.
Low Cost of Ownership
An electronic trip protects the individual source outputs against the accidental application of reverse power.
Careful attention to the thermal design and the use of well-proven signal generator modules gives high reliability and calibration validity.
The use of flash memory and software download via the RS-232 interface means the 2026A/B family can be upgraded with its covers fitted.
OPTIONS
Option 001 - Third Source
The 2026A/B family as standard is supplied with two RF sources. A version with 3 sources is available as an option to support appli­cations such as intermodulation tests on a receiver.
Option 003 - High Stability Time Base
For applications requiring improved frequency stability and close­in phase noise, the standard TCXO can be replaced by a high per­formance OCXO.
Option 004 - Rear Panel Connections
The RF connectors for all sources, their associated modulation and pulse inputs and the combiner output connector can be mounted on the rear panel for ease of use within an ATE environ­ment, as a factory option.
Option 116 - GSM PRBS Modulation
This options gives the 2026A/B family the capability for each source to emulate a GSM carrier.
This makes the 2026A/B suitable for performing test on GSM
multicarrier amplifiers and GSM receivers.
Option 117 - Bluetooth and GSM PRBS Modulation
This option provides modulation facilities for two Bluetooth modated carriers and a carrier emulating GSM Modulation.
SPECIFICATION
GENERAL DESCRIPTION
The 2026A/B MultiSource Generator family contains synthesized sig­nal generators offering up to three independent RF sources with sep­arate outputs or one or more of the signals routed via a combiner. The 2026B Signal Generator covers the range 10 kHz to 2.51 GHz. 2026A Signal Generators are limited to 2.05 GHz. An external sig­nal generator can be fed into the standard 2-source 2026A or 2026B. Each signal source can be controlled independently in fre­quency and level and each has its own amplitude, frequency, phase and pulse modulation capability. All parameters can be entered from the front panel keyboard and a rotary control can be used to adjust most settings. The following signal generator specifications apply to all of the sources fitted.
