ANRITSU me3401a

The ME3401A offers portability and easy operation and is ideal for
testing, evaluating, and monitoring DS-2, DS-1C, and DS-1 system
as well as the DS-3 system. This multifunctional instrument has five
error detection functions (bit, parity, frame, bipolar violation, and CRC-
6), seven measurement functions (error rate, error count, error seconds,
% error free seconds, threshold error seconds, error performance
data, and alarm seconds), jitter modulation and measurement
functions, and multiplexer test functions. These functions make the
ME3401A a powerful tool for commissioning, and production tests,
as well as for maintaining, and troubleshooting digital radios, fiber
optic systems, and digital multiplexers. In addition, live traffic performance
can be measured by using a wide input range, the frame error
detection function, the demultiplex function, and the built-in printer.
The printer outputs the measurement results and automatically
records the time, and contents when an error or alarm occurs. The receiver
makes it easy to measure the error rate or error count distribution
and error performance*.
