About the 50 ohm matching adapter :
Match the clock input 75Ω impedance of the audio equipment to 50Ω.
The 50Ω output of our clock products is ideal for connecting to 75Ω audio equipment.
Due to the combined resistance method, the quality of the clock is hardly deteriorated.
All products can be used with peace of mind by measuring the SWR for each unit and confirming the characteristics.
・SWR 1.03 or less (10 MHz when connected to 75 Ω impedance input device)
・Compatible impedance: Clock input side 50Ω Audio equipment output side 75Ω
[ Note ]
* This adapter cannot be used on the 75Ω output side.
* Since it is not an impedance converter, it is not possible to connect a cable to the 75Ω side. Be sure to connect it directly to the 75Ω input BNC connector of the audio device.
* When using this adapter, connect the devices with a 50Ω BNC cable. It will be inconsistent with a 75Ω cable.
* Only for our 10MHz clock products. We cannot guarantee the characteristics when the conditions are different, such as other frequencies.
Connection example :
OCXO OP21E-1 50ohm output -> 50ohm cable -> 50 ohm matching adaptor -> MC3+USB (75ohm input )
