Full RF spectrum support, extremely high-speed scan, wideband digital output, and configurable narrowband receivers (DDC's) offer new applications for signal search and analysis. Compared to other receivers the fast scan of 100 GHz/s over the entire frequency range significantly reduces the time needed to create a list of emissions prior to final analysis. The signal search and alert feature is a very efficient and flexible tool for observation of multiple signals of interest at the same time. These outstanding benefits, combined in just one device, allow the user to save and focus the resources.

SIR 2175 is a version for VHF/UHF Direction finding (DF)

Enhanced NB DDCs

The option enables additional enhanced bandwidths of 6.25 kHz, 12.5 kHz and 25 kHz for the narrowband DDCs of the SIR 2115. These additional bandwidths are available for the HF (shortwave) and V/UHF radio frequency range.

HF Multiplex Mode

The HF multiplex mode can e.g. be used to monitor the entire HF (shortwave) radio frequency range (9 kHz to 30 MHz) by only using one destined multiplexed output data stream.

Delay memory

The SIR 2115 has a internal memory that allows to delay the output data for the narrowband and broadband DDC. This delay can be used e.g. to compensate for system latencies that elapse between the detection of a signal and the commanding of a corresponding narrowband or broadband DDC channel. By delaying it can be ensured that "the first bit" of a transmission can also be evaluated. The delay memory (internal buffer) allows a delay time of up to 16 seconds.

80 MHz Total Bandwidth Output

This option enables the output of the total bandwidth of 80 MHz in one complete I/Q data stream. This means that the complete receiver bandwidth of 80 MHz of the SIR 2115 can be processed at once. This is essential for real time broadband signal analysis.
