3.1 Introduction
The AI-5120 Instrument Suite is a Windows 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.
Note: The AI-5120 Instrument Suite (p/n: AI-SS100) is an optional software program,
and not part of the basic AI-5120 package.
The figure below shows an example of the oscilloscope capturing a DTMF digit
generated by a telephone. 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 key specifications for the DSO are presented in the following table:
Bandwidth 100Hz to 10kHz
Accuracy* ±
0.2 dBV (100Hz to 10kHz)
Maximum Capture Time 5 seconds
