SIR-4000 Microwave Series

The SIR-4000 Microwave Receiver series is offered in three ranges of frequency coverage: 0.5 to 18 GHz, 0.5 to 26.5 GHz, and 0.5 to 40 GHz. All models have a tuning resolution of 10 Hz. The SIR-4000 receiver is designed to perform for today’s most demanding microwave signal monitoring applications. With its advanced RF/analog architecture, the SIR 4000 delivers high dynamic range and low spurious. Following the RF/analog frequency converter section in these receivers, a high-speed, high-resolution digital signal processor derives any of eight selectable IF bandwidths ranging from 0.5 MHz to 20 MHz at 70 MHz center frequency. Utilizing Elcom’s advanced frequency synthesizer architecture, which incorporates a direct digital synthesizer (DDS) within a VCO-based PLL synthesizer configuration, the tunable local oscillator (LO) of the SIR-4000 features low phase noise and fast tuning speed while allowing 10 MHz tuning frequency step size.

The Elcom SIR-4000 microwave receiver can be controlled remotely through any of multiple interfaces: Ethernet, RS 232, and RS 422. A front panel graphical display and front panel manual control capability are included. The receiver includes an independent analog L Band IF Output with 500 MHz or 1 GHz BW. Numerous advanced digital signal processing features within the SIR-4000 make available many functions which previously required external instrumentation. A high-speed digital controller within the SIR-4000 is programmed with an extensive set of instrument control functions making the SIR-4000 an extremely versatile microwave signal monitoring system.
