Perfection is a high standard - but your studio clocks deserve nothing less. That's why Stanford Research Systems designed the SRS PERF10, to offer audio professionals and demanding audiophiles a frequency reference of staggering accuracy and unmatched stability.

Up until now, atomic clocks marketed for audio use have been designed around commercial off-the-shelf rubidium clocks designed for the communications market-not audio. And while these rubidium clocks may have good long-term stability, they were never designed to provide low short-term jitter.

The PERF10 is built around Stanford Research Systems' own PRS10 rubidium oscillator. By designing and building the oscillators ourselves, we're able to craft an instrument perfectly matched to the demanding requirements of audio master clocks. Starting with an oven stabilized, 3rd overtone, varactor tuned, SC-cut crystal oscillator, the PERF10 offers both the accuracy and stability associated with rubidium clocks and unmatched jitter performance - 30 db better phase noise at 10 Hz off carrier than a competing "Swiss-made" rubidium clock.

And because we don't have to buy our oscillators from an outside source, we can offer you perfection - at an affordable price. PERF10 has eight 10 MHz, 75 Ω outputs compatible with all master clocks that accept a 10 MHz reference input.

Option 01 allows the unit to be powered from an external 12 VDC power source. When equipped with Option 01 PERF10 can be powered solely from an 12 VDC source, or the DC and AC power sources can be connected simultaneously with the DC supply providing an automatically switched redundant power source in the event of an AC failure.
