10 - Switching Between Single- and Three-phase Operation (Agilent 6834B only)
When shipped from the factory, the Agilent 6834B ac source is configured for three-phase operation.
You can configure the Agilent 6834B for single-phase operation. This increases the available output
power for phase 1 from 1.5 kVA to 4.5 kVA.
NOTE: When you configure the Agilent 6834B for single-phase operation, the phase 2 and phase
3 output terminals are internally connected to the phase 1 output terminal. This
distributes the increased available output power across the three output terminals.
Additionally, switching the Agilent 6834B between single-phase and three-phase operation causes the
following actions:
♦ it disables all outputs
♦ it reconfigures the current readback and programming calibration constants
♦ it returns all lists and *RCL states to their factory default states
♦ it reboots the unit, after which the newly selected number of phases becomes available
NOTE: This may require you to reprogram the lists and recall states each time the outputs are
switched.
