The Marconi IFR Aeroflex 2019A is a synthesized signal generator delivering AM, FM, and phase modulation across 80 kHz to 1040 MHz. Microprocessor control with direct keyboard entry provides straightforward operation, while optional GPIB programmability integrates the instrument into automated test systems. Non-volatile memory stores up to 100 settings, accelerating setup cycles in development, production, maintenance, and military environments.
Technical Specifications
Frequency Range: 80 kHz to 1040 MHz with 10 Hz resolution to 520 MHz and 20 Hz resolution to 1040 MHz.
Output Level: −127 dBm to +13 dBm (0.2 µV to 2 V e.m.f.) in CW, FM, and AM modes. AM mode delivers up to +7 dBm; pulse modulation reduces peak output to +3 dBm. Output resolution is 0.1 dB or better.
Output Accuracy: ±1 dB to 520 MHz; ±2 dB from 520 MHz to 1040 MHz. Output impedance is 50 Ohms with 50 W reverse power protection.
Harmonics: <−30 dBc (80 kHz to 520 MHz); <−20 dBc (520 MHz to 1040 MHz).
Modulation Capabilities: AM depth to 99%; FM deviation to 10.4 MHz; phase modulation deviation to 1040 radians. Six fixed internal modulation frequencies with user-selectable alternatives. External modulation inputs: FM (50 Hz–100 kHz), PM (50 Hz–10 kHz), AM (20 Hz–50 kHz DC-coupled). Modulation leveling is standard and can be disabled. Auxiliary FM input supports mixing with internal or external sources.
Frequency Standard: Provision for external 1 MHz or 10 MHz reference.
Power: 105–125 VAC or 210–250 VAC, 50–460 Hz.
