This bar graph is updated every hour. It lets you see at a glance how well each standard is performing. The graph documents the calibration in case questions arise in the future. You can also print a statistical summary of the data, or a listing of the data in tabular form. The software allows you to graph the performance of a frequency standard over periods ranging from 2 seconds to 150 days.
All data recorded by the system is stored on a solid state disk.
At any time, you can retrieve and graph past data recorded by the system. This gives you a permanent history of all frequency calibrations made by your laboratory. NIST regularly checks each system by modem to insure proper operation. The calibration report includes a graph of the primary standard's performance, and an uncertainty statement. Up to 5 frequency standards can be calibrated at one time.
