...analog and digital (T1/E1) microwave radios by replacing cavity-tuned oscillators which have been discontinued, obsoleted, or are otherwise no longer supported by original equipment manufacturers. The MRO operates in the S-, C- and X-bands frequencies and features form-fit-function compatibility with older, manually-tuned cavity oscillators. The devices are serially-programmable to within 1KHz of desired frequency which can then be manually tuned to a precise desired frequency of operation. The device includes an internal reference and non-volatile memory. Features include...

• Designed to Replace Obsolete Cavity Oscillators in Analog and Digital (T1/E1) Microwave Radios—this means no warm-up time. The old devices were free running and took almost a minute to acquire signal. The MRO has instantaneous turn-on time which allows for easy operation and quick maintainence.
• No frequency drift. The MRO is a phase-locked source that maintains frequency, whereas, the cavity oscillators were free running devices that required warm-up and heat sinking to maintain frequency
• Serially-Programmable / Manually Fine-Tuned
• High Stability, <±1ppm (-10°C to +70°C)
• Non-Volatile Memory
• Internal Reference. The devices are phase-locked to an internal reference
