VOLT 0 2. Set the triggered voltage to 120 V rms. In the Voltage menu, press o to VOLT:T 120 access the triggered voltage command. Then press 1 2 0 Enter. 3. Set the voltage mode to step. In the Voltage menu, press o to access the VOLT:M STEP mode command. Press ° to scroll to STEP and press Enter. 4. Make sure the unit is operating in the low voltage range. (The low voltage RANGE 150 range has twice the output current rating of the high voltage range.) In the Voltage menu, press o to access the range command. If necessary, press ° to set the range to 150 and press Enter. 5. Make sure the triggered voltage slew rate is set to the fastest possible speed. SLEW:T 9.9000+E37 In the Voltage menu, access the triggered slew command. If necessary, reset the slew rate to a faster speed. 6. Make sure the peak current and rms current limits are set to high values. In the CURR:LEV 6.5 Current menu, access the rms current limit and then the peak current limit CURR:PEAK 40 commands. If necessary, reset the rms current and the peak current limits to higher values. (Agilent 6811B units have an rms current limit of 3.25 A. Agilent 6813B units have an rms current limit of 13 A and a peak current limit of 80 A) 7. Synchronize the trigger source with a reference phase angle. In the Trigger SYNC:SOUR PHASE Control menu, press o to access the sync source command. Press ° to obtain PHASE and press Enter. 8. Set the reference phase angle to 75°. In the Trigger Control menu, press o to SYNC:PHAS 75 access the sync phase command. Then press 7 5 Enter. 9. Initiate (or enable) the unit for one immediate trigger from the front panel. INIT:IMMED Press Trigger Control and Enter. 10. Set the meter function to measure nonrepetitive peak inrush current. In the 0 A PK NR Meter menu, press o to access the peak inrush current display. 11. Enable the output by pressing Output On/Off. 0 V 60 HZ 12. Send the trigger to step the output from 0 V to 120 V. Press Shift Trigger. 48 A PK NR The inrush current is displayed on the Meter. On three-phase ac sources you can only return the peak inrush current from the selected phase because the front panel can only display one phase at a time. Refer to the ac source Programming Guide on how to return simultaneous measurements from all three phases. Front Panel Operation - 4 8 - Setting the GPIB Address and RS-232 Parameters Your ac source is shipped with the GPIB address set to 5 This address can only be changed from the front panel using the Address menu located under the Address key. This menu is also used to select the RS232 interface and specify RS-232 parameters such baud rate and parity. Action Display To set the GPIB address, proceed as follows: 1. On the System keypad, press Address. ADDRESS 5 2. Enter the new address. For example, Press 7, Enter. ADDRESS 7 To configure the RS-232 interface, proceed as follows: 1. On the System keypad, press Address. ADDRESS 5 2. Scroll through the Address menu by pressing o . The interface command INTF RS232 lets you select the RS-232 interface. The baudrate command lets you BAUDRATE 600 select the baudrate. The parity command lets you select the parity. PARITY EVEN 3. The . and ° keys let you select the command parameters. 9 - Saving and Recalling Operating States You can save up to 16 states (from location 0 to location 15) in non-volatile memory and recall them from the front panel. All programmable settings are saved. List data, however, cannot be saved in state storage. Only one list is saved in non-volatile memory. Action Display To save an operating state in location 1, proceed as follows: 1. Set the instrument to the operating state that you want to save. 2. Save this state to location 1. Press Shift Save 1 Enter. *SAV 1 To recall a saved state in location 1, proceed as follows: 1. Recall the state saved in location 1 by pressing Recall 1 Enter *RCL 1 To select the power-on state of the ac source, proceed as follows: 1. On the Function keypad, press Shift Output, and scroll through the Output PON:STATE RST menu until you get to the PON state command. 2. Use the . and ° keys to select either RST or RCL0. RST sets the power-on state of the unit as defined by the *RST command. RCL0 sets the power-on state of the unit to the state saved in *RCL location 0. To clear the non-volatile memory of the ac source, proceed as follows: 1. On the Function keypad, press Shift Output and scroll to the *RST *RST command. Then press Enter. This returns the unit to the factory-default settings. 2. Save these settings to location 1. Press Shift Save 1 Enter. *SAV 1 3. Repeat step #2 for memory locations 2 through 16.. *SAV 2 *SAV 3 *SAV 4 . . ...*SAV 16 4 - Front Panel Operation 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...
