Stanford Research SR625 Frequency Counter
The Stanford Research SR625 Frequency Counter is an essential instrument designed for the precise calibration of base stations, transmitters, and various communication systems. When paired with the Stanford Research SR620 Frequency Counter, this unit achieves exceptional resolution, delivering the atomic accuracy derived from its rubidium timebase.
Low Drift, High Accuracy
Utilizing a superior rubidium timebase, the SR625 ensures outstanding short-term stability, making it a reliable choice for critical applications. Coupling the SR625 with the SR620 Frequency Counter and a high-accuracy rubidium oscillator (PRS10) grants direct frequency measurements up to 2 GHz, featuring an impressive twelve digits of resolution within a 100 s measurement window.
Simple, Portable Operation
The SR625 is engineered for efficiency in field applications, boasting a warm-up time of less than ten minutes. Its design includes an additional back-panel output that provides a rubidium-stabilized 10 MHz signal, which can easily drive other test equipment such as synthesizers or spectrum analyzers. Furthermore, standard GPIB and RS-232 interfaces facilitate complete control and data acquisition, allowing seamless integration with laboratory computers. Whether utilized for remote applications or laboratory calibration, the SR625 stands out as a benchmark of performance in the field of frequency counting.
