MY 70900 A will go to the prescribed frequency , but "jumps" 40 - 160 MHz intermittently.
the phase noise quality is good when locked. The 300 MHz reference oscillator is also very good and is not intermittent
Any thoughts on what I might start examining ?
The service manual that is available is without schematics , so any schematic help would be appreciated.
