ST 093 Digital Panoramic Receiver.

::user`s manual ::software

• The ST 093 is intended to be used as an
• Intermediate frequency (IF) signal analyzer for a scanning receiver
• Analyzer of cable lines
• Panoramic short-wave receiver, LF, MF, HF

The digital signal processing (DSP) algorithm used in the ST 093 is implemented using a high-speed programmable matrix and analog-to-digital (AD) converters with a broad dynamic range. The algorithm allows for:

• Immediate and real-time spectral and oscillographic analyses across the entire frequency range
• Waterfall display of spectrum analysis (with time as one of the dimensions)
• Digital quadrature heterodyning and digital signal filtering
• Vector analysis within the frequency band of up to 2 MHz
• Digital real-time demodulation of analog (AM, FM, etc.) and identification of digital (PSK, FSK, QAM, etc.) types of modulation
• Spectral and oscillographic analyses of the demodulated signal
• Generation of an audible demodulated signal at the line and headphones outputs
• Detection of non-stationary, pulse, and one-time radio-frequency (RF) signals of a very short duration.

The ST 093 uses original software running on a PC.
The software operates in two modes - Basic and Expert. Expert mode allows for a broad range of measuring of signal parameters, combining digital filters, and displaying the signal.
Optionally, we supply a DLL file so you can develop your own custom software.

HF input for connecting:

• IF scanning receiver
• Cable lines adaptor
• LF, MF or HF antenna

Analyzer of IF signals of scanning receivers

The ST 093 can operate with virtually any scanning receiver with an IF output (for example, AOR 5000, 82000, 8600). To accommodate various scanning receivers, you can adjust the ST 093's frequency range, intermediate frequency, width of the IF filter, frequency settling time, amplification, and data transmission rate for the RS-232 port. It is also possible to subtract damaged content of the IF spectrum of a scanning receiver.

Panoramic receiver

When an antenna is attached to the RF input, the ST 093 becomes a panoramic short-wave receiver with a frequency range of 0.03–30MHz.
