If you don't see it, you probably wont get it.Specifications are from Ball/Efratom and may vary slightly due to upgrades, revisions or options this unit may or may not have.It  come with PDF  Manual.and TESTed and working great in my labIntroduction:The Efratom Model FRS Rubidium Standard is a subminiature, atomic resonance-controlled oscillator which provides an extremely pure and stable sinusoidal signal of 10 MHz at 0.5 Vrms into a 50 ohm load. The FRS-C may be utilized in equipment requiring an extremely stable and precise frequency and under more benign environmental conditions such as the time base of frequency counters.Connections:All necessary connections for input and output signals are externally accessible. Output signal, power, frequency adjustment,Features:For Time Base ApplicationsFor Use in Instruments, Receivers, Test Equipment, and NetworksSmall PackageLow Power ConsumptionElectrical Specifications:Output: 10 MHz Sine Wave, 0.5 +/- 30/10 % Vrms into 50 Ohm, set to 10 MHz +/- 5x10-11 from factory.Input Power: After warm-up, 10 W at 24 VDC at 25 °C ambient.Reg.
