Line Injector
J2120A
-
While the injection transformer is a very wideband adapter, it is not useful for measuring ripple rejection (PSRR) of a power supply or even an opamp. This is because the attributes that make the injection transformer perform so well also result in a transformer that is intolerant of DC current. Even very small DC currents (5mA or less) can greatly reduce the signal capacity or even totally saturate the transformer. For this reason, the Picotest line injector (J2120A) is another essential test adapter.

Loop A Line Products
-
Cable pair tracing and a lot more, Loop-a-Line products can remotely control a far end device (the oscillator) for up to 20km of cable. Using a Loop-a-Line allows the linesman to remotely change the state of the oscillator to any of five different states. Therefore eliminating the need for multiple journeys along the cable path.

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.

-
Peaceful Thriving Enterprise Co Ltd
The AC line splitter is a helpful testing device for electrician. Electrician can measure the current with clamp meter through the X1 and X10 measuring rings. X1 is 1:1 measurement, and X10 is ten times (1:10) of the actual current, which is helpful for small current measurement. This device also combines the function of socket tester and GFCI tester, which means electrician can use this tester to test socket and load at the same time.
