Marconi 2022D signal generator.

The Marconi 2022D Signal Generator is a compact, lightweight unit offering frequency, phase and amplitude modulation over the frequency range 10 kHz to 1 GHz. Output levels from -127 dBm up to +13 dBm are provided and the unit is designed for a wide range of applications in research, development, production and maintenance. Microprocessor control provides simple and rapid operation via direct keyboard entry of settings. The non-volatile memory, which can store up to one hundred settings, further reduces measurement time. Full GPIB programmability adds greater flexibility and faster throughput in systems applications.
