Information
INTRODUCTION
The 2022E Signal Generator is supplied as part of the
52022-599L Signal Generator Set together with various
accessories.
FEATURES
The 2022E is a light-weight synthesized signal generator
having a frequency range of 10 kHz to 1.01 GHz and providing
comprehensive amplitude, frequency and phase modulation
facilities with an RF output level range of -127 dBm to +10
dBm. It is designed to cover a wide range of RF applications
in development, production and maintenance. Output frequency
is phase locked to an internal or external frequency
standard and frequencies up to 100 MHz can be set to a
resolution of 10 Hz, and above that to a resolution of 100 Hz.

Front panel operation is carried out by direct entry of
required settings via the keyboard. Microprocessor control
ensures flexibility, simplicity of use and allows
programming by the General Purpose Interface Bus (GPIB).*
This enables the instrument to be used both as a manually
operated bench mounted instrument or as part of a fully
automated test system.
Output
Calibrated output levels from -127 dBm to +10 dBm. are
provided. A choice of ten output level unit combinations can
be obtained on. the front panel. The RF output level can. be
set to a resolution of 0.1 dB over the entire output,
voltage range. .Protection against the accidental,
application, of up to 50 W of reverse power is provided by a
fast responding relay trip. Full protection is also
provided, when the instrument is switched
An .RF level offset capability allows the output level to be
varied, relative to the indicated value to compensate for
external cable losses or to ensure that all instruments in a
particular area give identical results,
Modulation.
.Amplitude, frequency and phase modulation can be provided
from internal or external sources. AM depth can. be set in.
0.5% steps up to 99.5%, FM deviation up to 999 kHz and.
phase modulation up to 9.99 radians. An. auxiliary
modulation input, allows dual, modulation to be applied, for
receiver testing.
An internal, modulation oscillator provides switch selected
frequencies of 400 Hz,
1 'kHz and 5 kHz.
Front panel
All data and units selected are visible on a single liquid
crystal display. Data is entered on a keyboard that has
been, designed to be simple and logical to use. Carrier
frequency, modulation and .RF' level functions may be
incremented or decremented using the f (UP) and. l (DOWN)
keys. Non-volatile store and recall facilities are also
provided using an electrically alterable read, only memory
that does not require a battery back-up system. A. front
panel cover for protecting the instrument in transit is
available as an accessory.
Second function mode of operation
This enables a number of auxiliary functions such as setting
the GPIB address, selection of alternative RF level
calibration units, access to various calibration routines
and. an aid to diagnostic fault finding via the internal
instrument bus.
