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
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)
(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).
Set the voltage

Set the rms current limit (and peak current on Agilent 6811B/6812B/6813B units)
CURR:LEV 10
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 &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
current limit active
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
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.
120 V rms
Program a protection function

12 Quick Start Guide
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.

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.

&%Index Functions
These are ShiftIndex keys which areused to scroll through indexed
functions.Press these keys to step through integers 0 through 50 for a
harmonic list, or 0 through 99 forlist points. Hold down these keys to
rapidlyaccess any harmonicor list point.
&%Functions
These keys let you move through the choices in a command list.
Command lists are circular; you can return to the starting position by
continuously pressing either key.
This key applies to 3-phase ac sources only.
Pressing this keysuccessively selects phase 1
first, followed by phase 2, phase 3, and then all
threephases.
This key toggles the output on and off. When off,
the ac source output is disabled and the Dis
annunciator is on.
