GENERAL INFORMATION

INTRODUCTION
The 2030 series Signal Generators cover the frequency ranges 10 kHz to 5.4 GHz with
three models: 2030 (10 kHz to 1.35 GHz), 2031 (10 kHz to 2.7 GHz) and 2032 (10 kHz to 5.4
GHz). A dot matrix display with soft key selected screen options allow flexibility of operation
and ease of use. The output may be amplitude, phase, or frequency modulated with pulse
modulation available as an option. Modulation is available using a combination of up to two
external signal inputs and a built-in LF source.
Available options include a second build-in modulation source; avionics modulation (ILS
and VOR); pulse modulation; RF level profiling and complex sweep; electronic attenuator.
Microprocessor control ensures that the instruments are flexible and easy to use and
allows programming by the General Purpose Interface Bus (GPIB). 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 instruments 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
soft keys or the rotary knob. Hard keys have single or dual functions which remain constant
throughout, whereas soft keys have functions dependent on the present mode of operation.
Parameters may be set to specific values by numeric key entry, while values may be varied in
steps of any size using the ⇑/⇓ keys or altered by moving the knob, set to a particular sensitivity.
The SIG GEN, LF, SWEEP, MEM (memory), Δ (delta) and UTIL (utility) menus are
selectable, at any point of operation, via the keys below the display panel. Within the display,
the soft key functions are indicated by labels which appear alongside the keys situated at either
side of the display panel.
Display
The display is a dot matrix liquid crystal panel, with backlighting. Carrier frequency,
modulation and RF level are shown in horizontal regions on the principal screen. The display
features 11-digit resolution for carrier frequency, 4-digit for RF level and 3-digit for modulation,
with unit annunciators.
Contrast may be varied, using the control knob, to optimize the viewing angle. Differing
lighting conditions may be accommodated using the backlight intensity function, variable from
no backlight to full intensity. A full graphical display test is available, refer to the Service
Manual.
Frequency selection
Carrier frequency is selected via the soft key option on the SIG GEN display and direct
entry via the keyboard. Alternatively, selection may be made via the General Purpose Interface
Bus (GPIB). Frequency resolution is 0.1 Hz across the band. Carrier frequencies can be stored
in a non-volatile memory with complete recall when required. An ON-OFF key is provided to
completely disable the output.
