Introduction

The 2026 is a multisource signal generator offering as standard two signal sources in one
instrument. Up to three sources may be fitted, 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 network before being fed to a separate combined RF output. All sources
cover the frequency range 10 kHz to 2.4 GHz. An additional RF input is provided to enable the
output from an external RF signal generator to be combined with the signals from up to two
internal sources.

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 includes a GPIB interface which allows remote control of all standard signal generator
functions except the supply switch.

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.

GENERAL INFORMATION

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.

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 +4 dBm up to 1.2 GHz (0 dBm up to

2.4 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 keypress.

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.

Ø][×] keys or altered by

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 LF signal as well as providing an input
for external modulation signals to be combined with the internal signals. These sources can be
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 ΦM and 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.

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 manually altered.
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.

GENERAL INFORMATION

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 digitally derived. 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).

INSTALLATION

WARNING

Initial visual inspection

After unpacking the instrument, inspect the shipping container and its cushioning material for
signs of stress or damage. If damage is identified, retain the packing material for examination by
the carrier in the event that a claim is made. Examine the instrument for signs of damage; do not
connect the instrument to a supply when damage is present, internal electrical damage could result
in shock if the instrument is turned on.

Mounting arrangements

Excessive temperatures may affect the performance of the instrument. Completely remove the
plastic cover, if one is supplied over the case, and avoid standing the instrument on or close to
other equipment which is hot.

Installation requirements

Ventilation

This instrument is forced-air cooled by a fan mounted on the rear panel. Air must be allowed to
circulate freely through the ventilator grills located on the side and underside of the instrument.
Before switching on the instrument, ensure that the fan outlet on the rear panel is not restricted
(i.e. clearance of at least 75 mm (3 in) at the rear, 25 mm (1 in) at each side, 15 mm (0.5 in) on the
underside). Failure to provide adequate clearances will increase internal temperatures and reduce
the instrument’s reliability, so that its performance may not meet specification.

Class I power cords (3-core)

General

When the equipment has to be plugged into a Class II (ungrounded) 2-terminal socket outlet, the
cable should either be fitted with a 3-pin Class I plug and used in conjunction with an adapter
incorporating a ground wire, or be fitted with a Class II plug with an integral ground wire. The
ground wire must be securely fastened to ground. Grounding one terminal on a 2-terminal socket
will not provide adequate protection.

In the event that a molded plug has to be removed from a lead, it must be disposed of immediately.
A plug with bare flexible cords is hazardous if engaged in a live socket outlet.

Power cords with the following terminations are available from IFR Ltd. Please check with your
local sales office for availability.

2-2 46882/439

This equipment is provided with a 3-wire (grounded) cordset which includes a molded IEC 320
connector for connection to the equipment. The cable must be fitted with an approved plug which,
when plugged into an appropriate 3-terminal socket outlet, grounds the case of the equipment.
Failure to ground the equipment may expose the operator to hazardous voltage levels. Depending
upon the destination country, the color coding of the wires will differ:
