The IFR-Aeroflex 2042 5.4 GHz Low Noise Signal Generator has a choice of operating modes, two low noise modes for improved SSB phase noise and normal mode for increased flexibility, the 2042 can be used in a wide variety of applications. Microprocessor control coupled with a large screen dot matrix display provides ease of use via menu driven displays. Set up time is further reduced by recalling previously stored instrument settings from the non-volatile memory. Remote programming via the GPIB is provided as a standard feature, allowing the instruments to be incorporated in automatic test systems. With a specified SSB phase noise performance of better than - 140 dBc/Hz at 20 kHz offset from a carrier of 1 GHz, the 2042 of signal generator is easily able to measure UHF receiver selectivities beyond 90 dB. The low residual FM noise figure (less than 0.3 Hz RMS at 1 GHz) gives the 2042 the capability of measuring UHF receiver signal to noise ratios as high as 80 dB. Carrier frequency entry is selected via a soft key option on the signal generator screen and data is then entered directly via the keyboard. Frequency is resolved to within 0.1 Hz across the complete range of the instrument. Carrier frequencies can be stored in the non-volatile memory for recall at any time. RF output up to +13 dBm can be set by direct keyboard entry with a resolution of 0.1 dB or better over the entire range. An electronic trip protects the generator output against reverse power of up to 50 W, preventing damage to output circuits when RF or DC power is accidentally applied. An internal modulation oscillator is provided with a frequency range of 0.1 Hz to 500 kHz, resolved to 0.1 Hz. Four modulation modes are provided - single, dual, composite and dual composite. Specifications. Carrier Frequency Range: 10 kHz to 5.4 GHz. Resolution: 0.1 Hz. RF Output Range: - 144 dBm to +13 dBm, When AM is selected the maximum output level reduces linearly with AM depth to + 7 dBm at maximum AM depth. Resolution: 0.1 dB. Modulation Oscillator Frequency Range: 0.1 Hz to 500 kHz. Option 001, Second internal modulation oscillator. Option 002, Pulse Modulation. Option 006, Avionics (requires Option 001, not with Option 003). Option 008, RF Profile and Complex Sweep. Option 105, Modifies the pulse modulation option for slower rise and fall time (order with Option 002). Option 112, Ext. mod 2 Input 600 ohm.
