8-Channel, 10 MHz Precision ReferenceWith Sine and Logic Outputs
ITS-6200
-
The ITS-6200 is a versatile 10 MHz laboratory frequency reference useful for synchronizing test instruments to a common standard. Eight outputs are provided, each which can be configured independently as sinewave or logic level square-wave signals. Additionally, CMOS logic levels can be set for 5V, 3.3V, or 2.5V logic family compatibility. A 10 MHz reference input is provided to phase lock the ITS-6200 to an external reference, such as a GPS or Rubidium standard, or cascade multiple ITS-6200 units for additional outputs. The low phase noise and high stability OCXO within the ITS-6200 is suitable for the most demanding applications, whether free-running or phase locked. The compact size and low power consumption makes the instrument highly portable and suitable for AC-powered operation in the lab or battery operation in mobile or field applications.
