Introduction
The 2026Q CDMA Interferer MultiSource Generator is a purpose-built instrument for testing
CDMA handset and base station equipment. It features two synthesized RF signal sources with
both independent and combined RF outputs. An RF input is provided which enables the output
from a radio test set (or external RF signal generator) to be combined with the two internal signal
sources. The combined RF output provides a path to and from the radio under test and an
appropriate CDMA radio test set. Each signal source covers the frequency range 10 kHz to
2.4 GHz, whilst the combined path covers the range 800 MHz to 2.0 GHz.
It is designed to produce a fully calibrated combined RF output containing any combination of
internally generated interference signals from its two RF sources, together with a calibrated signal
path for a radio test set transmit output. A return path from the transceiver back to the radio test
set receiver input is also provided through the instrument (see Fig. 1-1 below).

receiver to be tested for sensitivity in the presence of dual tone interference and in accordance with
IS95A. This is specifically aimed at testing the receiver’s ability to successfully hand off to other
radio channels and between cellular and PCS bands. The interfering signals are combined without
the need for any RF switching mechanism that would otherwise affect the test result.
The 2026Q is configured to ensure high levels of isolation between each of the transmit and
receive paths between the radio test set, the interfering signal sources and the transceiver under
test.
Path loss test data is supplied with the instrument for the frequency bands 865 to 895 MHz and
1750 to 1990 MHz. Drift influences within these bands is minimal ensuring a level accuracy of
better than ±0.25 dB. The frequency response across each of these bands is flat to within ±0.1 dB,
thus minimizing the need for additional system calibration.
The 2026Q used as a multisource signal generator offers as standard two signal sources in one
instrument, each of which is a fully functional modulated signal generator. Each source can
either be routed to its own individual RF output or switched to the input of an RF combiner
1-2
network before being fed to a separate combined RF output. Both sources cover the full frequency
range of 10 kHz to 2.4 GHz with an output power of between −137 and +24 dBm.
Each signal source can be controlled independently in frequency and level, and each has its own
amplitude, frequency, phase, FSK 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 instrument is provided with built-in tests specifically for use with two or three combined
sources such as for amplifier and receiver intermodulation tests and receiver selectivity tests. The
sources may be locked together, offset in frequency (additionally with a harmonic or sub-harmonic
relationship) as well as level.
Microprocessor control ensures that the instrument is flexible and easy to use and allows
programming by the General Purpose Interface Bus (GPIB) or RS-232 serial bus. The GPIB is
designed to IEEE Standard 488.2 and is a means of sending commands to an instrument, via a data
bus, from a remote controller or personal computer. The instrument can therefore be used
manually or as part of a fully automated test system.
Main features
Operation
Selection of parameters on the screen may involve one or more of the numeric, hard or menu
selection keys or the rotary control knob. Parameters may be set to specific values by numeric key
entry, while values may be varied in steps of any size using the [
moving the control knob, set to a particular sensitivity.
GENERAL INFORMATION
Ø][×] keys or altered by
Display
The display is a dot-matrix liquid-crystal panel, with backlighting. Display contrast and brightness
may be varied to accommodate differing lighting conditions and the setting saved in memory.
Frequency selection
Carrier frequency is either selected directly via the keyboard or remotely via the interfaces.
Frequency resolution is 1 Hz across the complete frequency range of 10 kHz to 2.4 GHz. A series
of carrier frequencies can be stored in non-volatile memory for recall when required.
Output
Peak RF output levels from each signal source of up to +24 dBm can be set up to 1.2 GHz
(+20 dBm up to 2.4 GHz) by direct keyboard entry with a resolution of 0.1 dB down to
−137 dBm. The peak output level from the combiner is −3 dBm, 800 MHz to 2 GHz. RF
ON/OFF keys are provided to disable each individual output as well as the combined output.
A choice of level units is available to the user and provision is made for the conversion of units
(for example, dBm to µV) by a simple key-press.
An electronic trip protects each independent signal source output against reverse power of up to
50 W. This prevents damage to output circuits when RF transmitter or DC power supply is
accidentally applied to an RF OUTPUT connector.
To facilitate testing of receiver squelch systems, an attenuator hold function allows control of the
RF output without introducing RF level drop-outs from the step attenuator.
Modulation
Comprehensive amplitude, frequency and phase modulations are available. Pulse modulation can
be applied to the carrier from an external pulse source. The instrument also produces FSK
modulated outputs. An internal modulation oscillator is provided, having a frequency range
of 0.01 Hz to 20 kHz. Sine, triangle and square waveforms are available. The oscillator is capable
of generating one or two modulation tones simultaneously in one modulation channel. A BNC
connector on the front panel offers access to the internal LP signal as well as providing an input
for external modulation signals to be combined with the internal signals. These sources can be
1-3
combined to give a number of modulation modes. The pulse modulation can be used in
combination with the other forms of modulation.
The frequency modulation range provides a 1 dB bandwidth of typically 100 kHz and provides
FM deviation of 0 to 100 kHz. AC or DC coupled FM can be selected. Phase modulation is
provided with a 3 dB bandwidth of 10 kHz and deviation range of 0 to 10 radians.
Amplitude modulation with a 1 dB bandwidth of typically 30 kHz and with modulation depths of
up to 99.9% is available with a resolution of 0.1%. Pulse modulation is available as standard with
typical rise and fall times of less than 10 µs and 40 dB on/off ratio.
The instrument also accepts one or two logic level inputs to produce a 2-level or 4-level FSK
modulated output. The required FM deviation is set by keyboard entry.
The external input voltage required for specified modulation is 1 V RMS (1.414 V peak). To
accommodate other signal levels, Automatic Level Control (ALC) can be selected which provides
correctly calibrated modulation for inputs between 0.75 and 1.25 V RMS.
A modulation ON/OFF soft key simplifies the testing of signal-to-noise ratio.
Incrementing
All major parameters can be incremented or decremented in step sizes entered via keyboard entry
or remotely. If no step size is entered for a parameter, the steps are preset to 1 kHz for carrier
frequency, 1 kHz for modulation oscillator, 1 kHz for FM deviation, 0.1% for AM depth, 0.01 rad
for 1 dB for output level.
In addition, the rotary control knob can be used to vary the parameter with the sensitivity of the
knob being changed by means of the [×10] and [÷10] keys.
Control knob operation can be assigned for the adjustment of one parameter, while another
parameter is adjusted by the increment and decrement keys. By this means two parameters, for
example carrier frequency and RF level, can be adjusted simultaneously.
GENERAL INFORMATION
Frequency sweep
The sweep capability of the instrument allows comprehensive testing of systems. Four parameters
are used to specify sweep: start, stop, step size and time per step, all of which may be specified by
the user. The sweep can be paused at any time and the frequency and level altered manually.
During the sweep the RF level can be altered using the rotary control. Sweep triggering can be
single-shot or continuous and can be initiated directly or on the detection of a trigger. The
triggering signal may either be programmed or from a TTL signal applied to the rear-panel
TRIGGER 1 input. When frequency coupling is enabled, the coupled sources will track with the
swept source.
Memory
The instrument provides both non-volatile and volatile memory for storing instrument settings.
The non-volatile memory provides 100 full instrument settings and 100 settings of carrier
frequency only. The volatile memory (RAM) also provides 100 instrument settings. Any one of
the non-volatile instrument settings can be selected as the power-up setting for the instrument.
Software protection
To prevent accidental interference with the contents of internal memories, internal data is
protected.
Programming
A GPIB interface is fitted so that all functions are controllable via the interface bus which is
designed to the IEEE Standard 488.2. The instrument can function both as talker and listener.
The instrument also has an RS-232 interface which uses the common GPIB command set to
control the instrument and also allow new software upgrades or applications to be downloaded
into the instrument.

Calibration data
All alignment data is derived digitally. Realignment can be undertaken, without removing covers,
by protected front-panel functions or via the GPIB interface.
Spectral purity
With an SSB phase noise performance of typically −121 dBc/Hz at 20 kHz offset from a 1 GHz
carrier, these instruments can be used for both in-channel and adjacent channel receiver
measurements. Harmonically-related signals and non-harmonics are typically better than −30 dBc
and −60 dBc respectively.
Calibration
This instrument has a recommended two-year calibration interval after which it should be returned
for recalibration (for addresses refer to ‘International Service Centers’ section at end of manual).
