Telephone Line Monitor
AI-5120
-
The AI-5120 is a compact device designed for monitoring and analyzing signals present on the telephone line. By sensing the voltage present on the telephone line it detects and measures ringing, DTMF & pulse dialing, FSK (Bell 202 and V.23) signals, line polarity reversals, and open switching intervals (OSI). Working in conjunction with the TRsSim software on a PC, the AI-5120 becomes a valuable tool in analyzing and debugging Caller ID and SMS (Short Message Service) data transmission. Like an oscilloscope, it can capture and display waveforms showing various signals present on the telephone line.

Transmission Line Probes
-
Transmission line probes are a special type of passive probe designed for use at very high frequencies. They replace the high impedance probe cable found in a traditional passive probe with a precision transmission line, with a characteristic impedance that matches the oscilloscope input (50 Ohm). This greatly reduces the input capacitance to a fraction of a picofarad, minimizing the loading of high frequency signals. A matching network at the tip increases the DC input resistance. While they have lower DC input resistance than a traditional passive probe (usually 500 Ohm) to 1kOhm), the input impedance of these probes remains nearly constant over their entire frequency range. A traditional /10 passive probe will have a 10 MOhm) input impedance at DC, however this impedance drops rapidly with frequency, passing below the input impedance of a transmission line probe at less than 100 MHz.

Telephone Test Sets
-
Telephone test sets are a standard among telephone linemen. For the past 100 years, a test set’s functionality hasn’t changed much. Times are changing, networks are changing and now butt sets are changing. No longer are they single-purpose tools but are evolving into full-fledged, multi-functional test sets. Enter Fluke Networks’ newest line of VDV (voice, data and video) telephone test sets. We’ve taken the best features from our existing line, added new technology and totally redesigned them to lighten up your tool belt.

Air Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.
