The availability of \u201ceasy to operate\u201d instrument of reduced size and weight and of exceptional accuracy and stability provides the user with great flexibility in using cesium standards for meeting the stringent requirements of navigation, communication and timing systems.The Cesium Clock is an atomic frequency standard based on a hyperfine transition in the ground state of the cesium 133 atom. The Cesium Clock is specifically designed and produced with the latest technology in a very compact and reduced size. Taking into consideration its unique reduced volume, this offers a set of operation features and performance without comparison on the market. Available with a long life cesium tube, this will meet the requirements where performances are needed over a long period of time.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2029 size-large aligncenter\" src=\"http:\/\/rktelesystem.com\/rktplgroup\/wp-content\/uploads\/2019\/11\/prc-1024x373.png\" alt=\"\" width=\"780\" height=\"284\" srcset=\"https:\/\/rktelesystem.com\/rktplgroup\/wp-content\/uploads\/2019\/11\/prc-1024x373.png 1024w, https:\/\/rktelesystem.com\/rktplgroup\/wp-content\/uploads\/2019\/11\/prc-600x219.png 600w, https:\/\/rktelesystem.com\/rktplgroup\/wp-content\/uploads\/2019\/11\/prc-300x109.png 300w, https:\/\/rktelesystem.com\/rktplgroup\/wp-content\/uploads\/2019\/11\/prc-768x280.png 768w, https:\/\/rktelesystem.com\/rktplgroup\/wp-content\/uploads\/2019\/11\/prc.png 1200w\" sizes=\"auto, (max-width: 780px) 100vw, 780px\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2030 aligncenter\" src=\"http:\/\/rktelesystem.com\/rktplgroup\/wp-content\/uploads\/2019\/11\/cesium.png\" alt=\"\" width=\"587\" height=\"540\" srcset=\"https:\/\/rktelesystem.com\/rktplgroup\/wp-content\/uploads\/2019\/11\/cesium.png 703w, https:\/\/rktelesystem.com\/rktplgroup\/wp-content\/uploads\/2019\/11\/cesium-600x552.png 600w, https:\/\/rktelesystem.com\/rktplgroup\/wp-content\/uploads\/2019\/11\/cesium-300x276.png 300w\" sizes=\"auto, (max-width: 587px) 100vw, 587px\" \/><\/p>\n<p><strong>Cesium performances characteristics<\/strong><\/p>\n<ul>\n<li>Frequency accuracy \u00b11&#215;10-12<\/li>\n<li>Reproducibility \u00b11&#215;10-12<\/li>\n<li>Short Term Stability : ADEV<br \/>\n1s 1.2&#215;10-11<br \/>\n10s 8.5&#215;10-12<br \/>\n100s 2.7&#215;10-12<br \/>\n1\u2019000s 8.5&#215;10-13<br \/>\n10\u2019000s 2.7&#215;10-13<br \/>\n100\u2019000s 8.5&#215;10-14<\/li>\n<li>Floor 5&#215;10-14<\/li>\n<li>Stability: Resolution &lt;1&#215;10-15<br \/>\nRange \u00b11&#215;10-9<\/li>\n<li>Warm-up time 45 minutes @ 25\u00b0C<\/li>\n<\/ul>\n<p><span style=\"color: #0000ff;\">Outputs<\/span><\/p>\n<ul>\n<li><strong>Direct outputs:\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 5MHz\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a010MHz<\/strong><\/li>\n<li>Amplitude\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 1Vrms \uf0b10,2@50\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a01Vrms \uf0b10,2@50\uf057<\/li>\n<li>SSB Phase<br \/>\n1Hz\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 &#8211;
