The 4935A is compatible with Bell standards. this test set provide measurements of level versus frequency, noise with various selectable filters, Signal-to-Noise Ratio, Noise with Tone, Three-level Impulse Nose and 4-wire single frequency return loss. The 4935A performs the required tests to qualify the local loop for Digital Dataphone Service up to 56 kbps. The Peak-to-Average-Ratio (P/AR) measurement option on the 4935A gives system users a powerful yet simple measure of the combined factors which effect the overall data transmission quality.
Telephone companies, PABX and other telecommunications equipment service people will find the 4935A has the analog testing capability they need. Both instruments include standard dial and hold capabilities, independent transmit and receive impedances, level zero function, SF skip and complete unit annunciation.
