The 3551A test set is designed to measure frequency and level of tone or noise on telecommunication ciruits, while simultaneously providing calibrated test signals. It is ideally suited for measurments on voice program and data circuits. The input can accept both two-wire and four-wire balanced lines. Frequency or level measurements of received signals can be made in either a bridged or terminated mode. Terminated impdeances can be selected at 135 Ω, 600 Ω, or 900 Ω. The source impedance of the calibrated test signals is always equal to the selected terminating impedance.
