Safety Notice

The beginning of the User’s Guide has a Safety Summary page for this instrument. Familiarize yourself with the contents of that page. The following safety precautions must be observed.

WARNING: LETHAL VOLTAGES Ac sources can supply 425 V peak at their output. DEATH on contact may result if the output terminals or circuits connected to the output are touched when power is applied.

BEFORE APPLYING POWER

Verify that the product is set to match the available line voltage, the correct fuse is installed, and all safety precautions are taken. Note the instrument’s external markings described under "Safety Symbols".

GROUND THE INSTRUMENT

To minimize shock hazard, the instrument chassis and cover must be connected to an electrical ground. The instrument must be connected to the ac power mains through a grounded power cable, with the ground wire firmly connected to an electrical ground (safety ground) at the power outlet. Any interruption of the protective (grounding) conductor or disconnection of the protective earth terminal will cause a potential shock hazard that could result in personal injury.

FUSES

Only fuses with the required rated current, voltage, and specified type (normal blow, time d elay, etc.) should be used. Do not use repaired fuses or short-circuited fuseholders. To do so could cause a shock or fire hazard.

DO NOT REMOVE THE INSTRUMENT COVER

Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made only by qualified service personnel.

DO NOT EXCEED INPUT RATINGS

This instrument may be equipped with a line filter to reduce electromagnetic interference and must be connected to a properly grounded receptacle to minimize electric shock hazard. Operation at line voltages or frequencies in excess of those stated on the line rating label may cause leakage current in excess of 5.0 mA

Some basic operations

Make sure the unit is turned on. Use either the front panel keys or the corresponding SCPI commands.

The column on the left indicates the front panel keys that program the indicated action. If the SCPI programming syntax is substantially different from the front panel menu command, it is shown inside parentheses ( ).

The text to the right describes the result. If appropriate, the resultant output waveshape is shown underneath the description.

Enable the output

Output On/Off

When the output is enabled, the programmed voltage appears at the output and the Dis annunciator turns off.

Select the output phase (Agilent 6834B only)

Phase Select

(INST:NSEL)

You can specify phases individually, or you can couple the phases. When phases are coupled, all three phase annunciators (φ1, φ2, φ3) on the front panel are on, indicating that commands will be sent to all three phases. Note that front panel metering is only done one phase at a time (except for the total power and neutral current measurements).

When this command is sent, the rms current limit is set to 10 A. If more current than the programmed limit is drawn, the output voltage amplitude is reduced to keep the rms current within the specified limit. Press Shift Current and q to access CURR:PEAK, which lets you set the peak current limit on Agilent 6811B/6812B/6813B units. Note that the peak current limit circuit on these units acts instantly and clips the output voltage to maintain the programmed peak limit.

120 V rms

NOTE: The rms current limit circuit is slower than the peak current limit circuit and, depending

on the setting of the peak current limit and the load on the output, your unit may generate momentary peak currents that can well exceed the rms current limit.

Select a waveshape

SHAPE SQUARE

Enter

When this command is sent, the output generates a squarewave. Note that the peak-to-peak amplitude of the squarewave is less that that of a sinewave when it is programmed to the same rms voltage amplitude.

Measuring the output

All measurements are based on acquiring and subsequently processing output waveform information. When the ac source is on, it takes measurements and updates the front panel meter continuously. The Meter key accesses the measurement functions from the front panel.

The SCPI MEASure command acquires new waveform information each time it is executed. The SCPI FETCh command does not acquire new waveform information but extracts the desired information from previously acquired waveform data. SCPI commands let you measure phases individually or simultaneously measure all phases using the FETCh command.

Measurement functions

The following example illustrates the measurements that can be returned by the front panel of the ac source when sourcing power to a typical non-resistive load such as a power supply. The ac source output voltage and current waveforms are shown on the next page.

NOTE: On Agilent 6811B, 6812B, and 6813B units, the Input key selects the meter coupling

and hence, what the meter will measure. The choices are: AC only, DC only, or AC + DC.

Programming output transients

Up to now the ac source has been programmed with the transient system in Fixed mode. The following examples briefly describe the transient system’s Step, Pulse, and List modes, which require the application of a trigger to implement the transient mode.

NOTE: For the examples that follow, press Shift Output, scroll to *RST and press Enter to

reset the unit prior to each example. Also press Enter to enter or activate each selection.

Pulse transients transition to a new output level upon receipt of a trigger and return to the original level after a specified time, repeating this action by the number of times specified by the count. When these commands are sent, two output pulses step the voltage amplitude from its previous setting to 90 V rms upon receipt of a trigger. At the end of the specified period (multiplied by the count), the voltage returns to its original level.

More about the trigger system

In the previous examples, a front panel trigger is used to generate the output transients. The trigger is shown occurring at 270 degrees but actual triggers may occur at any phase. Delay and phase synchronization however, will occur as programmed.

Note that trigger system used in the ac source provides great flexibility in generating triggers. The following figure is a simplified model of the trigger system. A complete discussion of the capabilities of the trigger system is found in the ac source Programming Guide.
