Marconi 2022D Generator
Modell: 2022D
Datum: 1993
Kategorie: Messgeräte
Gruppe: Generator
Beschreibung: 10 kHz - 1 GHz AM/FM SIGNAL GENERATOR
The 2022D is a light-weight synthesized signal generator
having a frequency range of 10 kHz to 1 GHz and providing
comprehensive amplitude, frequency and phase modulation
facilities with an RF output level range of -127 dBm to +13
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 facility is offered as an option enabling the
instrument to be used both as a manually operated bench
mounted instrument or as part of a fully automated test system.
Calibrated output levels from -127 dBm to +13 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 off.
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.
Amplitude, frequency and phase modulation can be provided by
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 3 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 t (UP) and i (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
Second function mode of operation
This enables a number of auxiliary functions such as setting
the GP1B 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.
