POWER Menu Variants - 4-Port VNAs
POWER Menu Name and Button Changes
The name of the POWER menu can be POWER or POWER [COUPLED] depending on the settings on the POWER SETUP menu.
• POWER: On the POWER SETUP menu, the Port Power button is set to Not Coupled.
• POWER [COUPLED]: On the POWER SETUP menu, the Port Power button is set to Coupled.
• On POWER menus with frequency-based sweeps, the button to link to the POWER SETUP menu is labeled the Other Setup button. These sweeps are Freq Sweep (Linear), Freq Sweep (Log), Segmented Sweep (Freq-based), and Segmented Sweep (Index-based). Note that the Other Setup button is not available with segmented sweeps.
• On POWER menus with power-based sweeps, the button to link to the POWER SETUP menu is labeled the Power Setup button. These sweeps are Power Sweep (CW Freq) and Power Sweep (Swept Freq).
