Marconi 2022 Generator
Modell: 2022
Datum: 1985
Kategorie: Messgeräte
Gruppe: Generator
Beschreibung: 10kHz-1000MHz AM/FM SIGNAL GENERATOR
                                    1» 2022 is a light-weight easily portable synthesized signal
generator. It has a frequency range of 10 kHz to 1000 MHz
and provides comprehensive amplitude, frequency and phase
modulation facilities. The instrument is designed to cover a
wide range of applications in both production and repair of
radio equipments. Output frequency is phase locked to an
internal or external frequency standard and frequencies up
to 1Ü0 MHz can be set to a resolution of 10 Hz, and above
that to a resolution of 100 Hz.
2. 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 optional accessory enabling
the instrument to be used both as a manually operated bench
mounted instrument or as part of a fully automated test system.
3. Calibrated output levels from -127 dBm to +6 dBm are
provided. A choice of ten output level unit combinations can
be obtained on the front panel. The r.f. output level can be
set to a resolution of U.I dB over the entire output voltage
range and features a total cumulative accuracy of better
than ±2 dB. Protection against the accidental application of
up to 25 W of reverse power is provided by a fast responding
relay trip.
4. Amplitude, frequency and phase modulation can be provided
internally or externally. AM depth can be set in 0.5% steps
up to 99.5% at carrier frequencies up to 400 MHz. FM is
available at all carrier frequencies and provides deviations
up to 99.9 kHz. Phase modulation is also available with a
range of up to 9.99 radians. *

5. 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 r.f. level functions may be
incremented or decremented using the t (UP) and Ψ (DOWN)
keys. Nonvolatile store and recall facilities are also
provided using an electrically alterable read only memory
that does not require a battery back-up system. Available
accessories include a front panel cover for protecting the
instrument in transit, ‘

6. This includes the means of setting the GPIB address,
selection of alternative r.f. level calibration units,
access to various calibration routines and a facility to aid
diagnostic fault finding via the internal instrument bus.
