AI-5120
Instrument Suite:Description:
The AI-5120 Instrument Suite is a Windows (98SE, 2000, XP)
software package allowing the AI-5120 Telephone Line Monitor to
operate as a digital storage oscilloscope (DSO) and spectrum analyzer.
The software enables the user to investigate the time domain and
frequency domain representation of signals through an intuitive
instrument like software interface.
full
screen view.
Similar to a conventional oscilloscope, controls located at the right side of the window determine various settings such as vertical scale, horizontal time base, trigger conditions, and cursors.
The DSO has a record depth of 5 seconds giving it the ability to capture long dialing or FSK messages, while still being able to zoom into the waveform for analyzing details.
The spectrum analyzer can operate simultaneously with the DSO or by itself.
Controls on the right side of the window allow adjustment of the frequency span, center frequency, reference level, and acquisition settings.
Both the center frequency and span are adjustable to a maximum limit
of 35 kHz. Additional features such as peak hold allow it to capture short transient signals, while averaging assists in measuring noise levels or repetitive signals.
