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.

Time Delay and Integration (TDI) Line Scan Camera
Piranha HS
-
The Piranha HS cameras provide an alternative to traditional line scan imaging. They enable you to meet the line rates and responsivity necessary for your high performance applications and allow you to reduce the number of cameras in your system. When you use fewer cameras, you use fewer framegrabbers, lenses, computers and cables. The Piranha HS family delivers the lowest price/pixel TDI system solution ever offered by Teledyne DALSA. Lighting costs can also be reduced. With TDI imaging, you can use LED lights, helping you to optimize system up-time and productivity.

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.
