YRS02 York Reference Source

The YRS02 is a multi-mode reference source capable of producing a broadband noise or comb output up to 1GHz.

• Selectable noise or comb output - Flexibility across a range of applications

•Stableoutput - Repeatable measurements

•5kHzto1GHzoutput - Applications across a broad frequency spectrum

•Compactandportable -Comparisonsbetweensitesandenvironments

•Batterypowered -Nopowerorinterconnectingcableeffects on measurements
