The SIR-1000 HF Receiver is designed for narrowband signal capture from 10 KHz to 30 MHz. With noise figure performance of 14 dB, maximum, multiple on-the-fly selectable digital IF bandwidths and a fixed 455 KHz IF output, the SIR-1000 is well suited to replace multiple legacy receivers with one universal solution. Add to this an input IP3 > 30 dBm, IP2 > 80 dBm and you have enhanced capability to improve signal detection even in the most sophisticated masking environments. Tuning speed as fast as 200 microseconds is available as an option, with 1 millisecond standard. Digitally enabled functions like IQ over Ethernet will make your systems integration task easier as the SIR-1000 eliminates the need for external IQ digitization.
The SIR-2000 VHF/UHF Receiver, covering 20 MHz to 3000 MHz, is, like the SIR 1000 HF series, designed for narrowband applications. Its fast, 1 millisecond, tuning speed provides exceptional scanning rates for demanding applications. Multiple selectable IF bandwidths extending from 6 KHz to 500 KHz are standard with 1 MHz through 10 MHz optional. In addition, the spurious free dynamic range (SFDR) of 80 dB and in band IP3 >+5 dBm provide for a signal sensitivity unavailable in similarly priced products.
The SIR-3200 VHF/UHF Receiver is designed for wideband applications from 20 MHz to 3000 MHz with multiple selectable digital IF bandwidths from 6 KHz up to 40 MHz, and fixed analog IF bandwidth outputs. This unique receiver has a spectral display, NRT and optional VOIP.
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 IF output having 1200 MHz center frequency and 500 MHz IF bandwidth. 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.
