Adjust Phase - Aux to Output
This slide-out menu is available for all Dual Output ac functions and adjusts the phase difference
between the Aux Output and the primary Output.
For Sine-Sine AC Power, the phase shift adjustments may be entered as a displacement power factor
(DPF) as well as in degrees. When you enter a power factor, this activates the Lead/Lag toggle. A
leading or positive phase shift causes the AUX waveform to lead the OUTPUT waveform; a lagging or
negative phase shift causes the AUX waveform to lag the OUTPUT waveform.
To adjust the phase:
1. Tap the Adjust Phase Aux to Output button ( ). A menu opens and shows the current degree,
or degree and power factor for Sine-Sine ACP.
2. Touch the deg or DPF white box and use the number pad to enter a value. If a DPF is entered, then
select Lead or Lag using the toggle.
3. Tap the Apply button or push E. This closes the menu. The entry is copied to the correct
output on the screen. Tapping x instead of Apply closes the menu without saving changes.
When you use the knob to adjust phase, changes are applied immediately and the Apply button
disappears. Push E or tap x to exit the slide-out. Tapping x does not revert changes.
Sync Button
The Sync button is available for Single Output and Dual Output ac functions. Because the button
requires a longer explanation, see Synchronize the Calibrator Using 10 MHz IN/OUT.
Comp Softkey
The Comp softkey is available in Single Output menu Resistance, Capacitance, and Inductance
functions. Compensation (Comp) Applies 4-wire compensation, 2-wire compensation or turns
compensation off. Compensation refers to methods of connecting the Calibrator to the DUT to cancel
out test lead resistance. See Four-Wire versus Two-Wire Connections for more information. For the
3-lead connection (Figure 9) select Comp OFF.
