General Information
OPTIONAL TIME BASE (Option
Option 001 provides a n oven controlled crystal oscillator time base with a n aging rate
near that of a time standard. This option results in better accuracy and longer periods
between calibration. A separate power supply keeps the crystal oven
temperature when the instrument is turned off as long as
power line.
