Rubidium Oscillator Timing Expansion Module

Product Overview The C5TEM-R2 is the 2nd generation Rubidium Timing Expansion Module (TEMv2) designed exclusively for VIAVI T-BERD/MTS-5800 handheld network tester. It integrates a miniature rubidium atomic clock and multi-constellation GNSS receiver, delivering nanosecond-level timing accuracy for synchronization testing in 5G/4G mobile backhaul, transport networks. It supports PTP, SyncE, wander and one-way delay measurement for telecom timing conformance validation. Key Features Built-in miniature rubidium oscillator for ultra-stable holdover performance Multi-constellation GNSS receiver for disciplined timing reference Nanosecond precision timestamp & time error measurement Supports IEEE 1588 PTPv2, Synchronous Ethernet (SyncE) testing Measure wander, cTE, dTE, Max|TE, one-way delay Provides 1 PPS input/output, 10 MHz reference clock I/O Optimized for field test of 5G RAN, transport and mobile fronthaul Hot-swappable module for T-BERD/MTS-5800 V2 mainframe
