Entry Description
Setting
CURRENT Programs the output current required as a load for the UUT.
PHASE SHIFT Programs the Phase shift required as a load for the UUT.
RANGE Displays 166 VAC or 333 VAC range for AC-mode, and 220 VDC
or 440 VDC range for DC-mode operation. The OUTPUT state
must be OFF for a change in range to be executed.
MODE Displays the source mode of operation.
SYNCHRONIZE Starts the Synchronization between Sequoia and EUT and once
the Synchronization is successful it will display “SYNCED”.
Measure
VOLTAGE Displays the true RMS value of the output voltage measured at
the voltage sense lines. In DC-mode only, the voltage is the DC
voltage including polarity.
CURRENT Displays the true RMS value of the output current. In DC mode
only, the current is the DC current including polarity.
FREQUENCY When in AC mode, the output frequency is measured at the
sense lines. When in DC mode, this value always reads “DC”.
5.8.4 Real-Time Parameter Adjustment
The DASHBOARD screen menu provides the capability for output parameter entry that has a real-time,
immediate effect on the output. This allows manual adjustment of the output parameters where the tuning
of a value is desired. Enabling this function requires tapping on a parameter selection-field box with the
encoder switch to select the parameter and display its selection-field highlighted and with a value entry
window. The rotary encoder could then be used to continuously adjust the parameter value, up and down,
as it is rotated. The value change takes immediate effect on the output.

5.8.5 Output Program Screen
The OUTPUT PROGRAM screen provides the setting of output-related items such as individual output
parameters, mode of regulation and current limit, output waveform selection, and display of real-time output
waveform or harmonics spectrum.
The top-level menus of the OUTPUT PROGRAM screen are shown in Figure 5-126. They could be
reached in one of two ways:
