Initial S/W Revision A.13.0
Timebase DAC
Allows control of the internal 10 MHz reference oscillator timebase. This may be used to adjust for minor
frequency alignment between the signal and the internal frequency reference. This adjustment has no
effect if the instrument is operating with an External Frequency Reference.
If the value of the Timebase DAC changes (by switching to Calibrated from User with User set to a different
value, or in User with a new value entered) an alignment may be necessary. The alignment system will
take appropriate action; which will either invoke an alignment or cause an Alert.

Notes If the value of the timebase is changed the alignment system automatically performs an alignment or
alerts that an alignment is due.
If the value of the timebase is changed the alignment system automatically performs an alignment or
