The 432DVM-9 is a device from Teledyne that measures and monitors frequency, phase, and synchronization of digital signals. It is designed for applications in radio broadcasting and telecommunications where precise timing and synchrony between devices are essential. The 432DVM-9 features time code input and output for synchronization to an external time source, such as an NTP or PTP server. It has four independent input channels which can measure frequency and phase of digital signal sources. It can be used to measure and monitor the performance of digital communication links and broadcasting systems, detect signal integrity issues, and troubleshoot disrupted channels. Other features include built-in signal monitoring and low-latency SNMP network controls, enabling easy integration into existing infrastructures.
