POWER SETUP Menu – Frequency-Based Sweep – 4-Port VNAs (1 of 2)
Menu Name Change
If Port Power is set to Not Coupled, when Port 1 is selected, the menu name changes to POWER SETUP [1]. Similar menu name changes occur for the remaining Port selections.
If Port Power is set to Coupled, the menu name changed to POWER SETUP [C]
Port Selection (Port 1/Port 2/Port 3/Port 4)
Select displays the SELECT PORT dialog box allowing touch screen selection of Port 1, Port 2, Port 3, or Port 4.

If Not Coupled is selected:
• The power level of the ports can be adjusted separately on the POWER and POWER SETUP menus.
• The Port Selection button (described above) toggles between Port 1 through Port 4, also changing the POWER SETUP menu name between POWER SETUP [1], POWER SETUP [2], POWER SETUP [3], or POWER SETUP [4].
If Coupled is selected:
• An adjustment to one port is also applied to the other port on the POWER and POWER SETUP menus.
• The Port Selection button (described above) toggles between Port 1 and Port 2.

LEVELING MODE Menu
Leveling Mode (Application | PulseView)
Visible only if the application is set to PulseView and allows the user to more precisely control power based on the signal envelope. Allows selection of:
• Real Time CW leveling mode – Level adjustments occur based upon detection of the CW non-pulsed signal. This will result in a leveling of average power, but occurs on a continuous (sub-microsecond) basis and has no impact on sweep time.
• Per Sweep leveling mode – Level adjustments occur on a per sweep basis targeting the specific portion of the pulse described by the reference measurement width and delay. The leveling adjustments only occur at the end of the sweep, so fast drift (by a pre-amplifier for example) will not be corrected. This approach has minimal impact on sweep time.
• Per Point leveling mode – Level adjustments occur on a per point basis targeting the specific portion of the pulse described by the reference measurement width and delay. The leveling adjustment is made at every point before the main measurement is made, so even fast drifts will be corrected. This approach has more impact on sweep time, but the power level at a specific point in the pulse is more precisely controlled.
Leveling Mode can be set in the LEVELING MODE menu, or in the PULSEVIEW CONFIGURATION dialog | Power tab.
Note 
If the application is set to PulseView and the Leveling Mode is set to Per Sweep Pulsed or Per Point Pulsed, the Refresh Leveling Ref. button will become available, which will allow the user to refresh the pulsed leveling reference target values. This action is recommended after recalling a pulsed leveling setup with a user power calibration or a pulsed user power calibration file, particularly if the proper measurement hardware connections were not in place at time of recall.
