10 MHz External Frequency Reference Input for the FLEX-5000 and FLEX-1500
Content provided by: FlexRadio Systems Engineering
Both the FLEX-5000 and FLEX-1500 have the facilities for connecting an external precision frequency reference for increased frequency accuracy and stability.
The specifications on the external frequency reference input are as follows:
After connecting an external frequency reference, you must configure PowerSDR to use the external reference by selecting "Use Ext. Ref Input" from the Setup->General->Hardware Config tab. See the Screen shot Below.
Since not all external frequency references are 100% accurate for their 10 MHz RF output, it is recommended that you run a frequency calibration using a known frequency source such as WWV.
