To keep the internal timebase frequency reference oven at operating temperature, the synthesizer must be connected to ac line power. The synthesizer requires approximately 30 minutes to warm up from a cold start before the OVEN display message goes off. With

a stable outside temperature, internal temperature equilibrium is reached after approximately two hours. For additional information on warmup times, see “Specifications,” in this volume.
