GENERAL

INFORMATION

46882-225U 1-1

GENERAL INFORMATION

Introduction

The 2023 and 2024 are portable and lightweight synthesized signal generators covering the
frequency range 9 kHz to 1.2 GHz (2023) and 9 kHz to 2.4 GHz (2024). A dot matrix display
with a comprehensive set of utility menus allow flexibility of operation and ease of use. The RF
output can be amplitude, frequency, phase or pulse modulated. An internal programmable AF
source is capable of generating simultaneous two-tone modulation.

All parameters can be entered from a front panel keyboard and a rotary control can be used to
adjust most settings. Microprocessor control ensures that the instruments are flexible and easy to
use and allows programming by either the General Purpose Interface Bus (GPIB) or by RS-232.
The GPIB is designed to IEEE Standard 488.2. The interfaces allow remote control of all
functions except the supply switch, and allow the instruments to be used either 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 DOWN/UP keys or altered by
moving the control knob, set to a particular sensitivity.

Display

The display is a dot matrix liquid crystal panel, with backlighting. Display contrast may be varied
to accommodate differing lighting conditions and the setting saved in memory. A graphical
display test is available to the user.

Frequency selection

Carrier frequency is either selected directly via the keyboard or remotely via the interfaces.
Frequency resolution is 1 Hz across the band. A series of carrier frequencies can be stored in non­volatile memory for recall when required.

Output

RF output up to +13 dBm can be set by direct keyboard entry with a resolution of 0.1 dB over the
entire range. For instruments fitted with the high power option, RF output is increased to
+25 dBm. A carrier ON/OFF key is provided to completely disable the 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 the generator output against reverse power of up to 50 W. This prevents
damage to output circuits when RF or DC power is accidentally applied to the 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.

The RF output level can be offset by up to ±5.0 dB to compensate for cable or switching losses, or
standardize a group of instruments.

Maximum RF output level can be set so as to protect sensitive devices connected to the RF
OUTPUT socket.

Spectral purity

Calibration

Modulation

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 -25 dBc
and -60 dBc respectively.

This instrument has a recommended two year calibration interval after which it should be returned
for recalibration (for addresses refer to 'Addresses' section at end of manual).

Comprehensive amplitude, frequency and phase modulations are available. Pulse modulation can
be applied to the carrier from an external pulse source. The instrument also accepts one or two
logic level inputs to produce a 2-level or 4-level FSK modulated output. An internal modulation
oscillator is provided, having a frequency range of 0.01 Hz to 20 kHz. The oscillator is capable of
generating one or two modulation tones simultaneously in one modulation channel. An
independent BNC input on the front panel allows external modulation signals to be combined with
the internal signal(s). 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 up to a maximum of 100 kHz. AC or DC coupled FM can be selected. Phase
modulation is also available with a 9 kHz bandwidth up to a maximum of 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 external input voltage required for 100% modulation is 1 V RMS or, optionally, 1 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 MOD ON/OFF key simplifies the testing of signal to noise ratio.
An optional fast pulse modulator improves the rise/fall times to typically 10 ns.

GENERAL

INFORMATION

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.

Frequency sweep

The sweep capability of the instrument allows comprehensive testing of systems. Sweeps may be
logarithmic or linear. Four parameters are used to specify sweep; start, stop, step size and time per
step and a percentage increment in the case of logarithmic sweep, all of which may be specified by
the user. The sweep can be paused at any time. 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 input.

Memory

The instrument provides both non-volatile and volatile memory for storing instrument settings.
The non-volatile memory provides 100 instrument settings and 100 settings of carrier frequency
only. The volatile memory (RAM) also provides 100 instrument settings. Any one of the non­volatile instrument settings can be selected as the power-up setting for the instrument.

46882-225U 1-3

GENERAL INFORMATION

Memory cloning

The stored settings in one instrument can be easily transferred (without the use of a controller) to
another instrument using the RS-232 interface, or to several other instruments using the GPIB
interface.

Memory sequencing

A software facility allows sequences of stored instrument settings to be defined. The incrementing
facilities can then be used to cycle through the settings in manually operated test systems or be
operated via an external trigger.

Memory protection

To prevent accidental change of the contents of the stored settings, individual memories or ranges
of memories can be write-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. The
interfaces enable the instrument to be remotely controlled as well as being used to transfer settings
(cloning) from one instrument to another.

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.

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.

Installation requirements

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.

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 at the rear, 25 mm at each side, 15 mm on the underside). Failure
to provide to adequate clearances will increase internal temperatures and reduce the instrument
reliability, so its performance may not meet specification.

Power cords

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 moulded 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.

This equipment is provided with a 3-wire (grounded) cordset which includes a moulded 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 colour coding of the wires will differ:-
