POWER SETUP Menu Variants - 4-Port VNAs
The presence of the menu and the button availability on the menu depends on the sweep type setting.
Sweep Type Frequency-Based
If Sweep Type = Frequency Based (Linear) or Frequency-Based (Log):
• The POWER SETUP menu has four (4) buttons.
• Available buttons are: Port Selection, Apply Slope (All Ports), Slope (dB/GHz), and Port Power mode.
Sweep Type Segment-Based
If Sweep Type = Segmented Sweep (Frequency-Based) or Segmented Sweep (Index-Based:
• The POWER SETUP menu is not available.
• All power setup related configurations are completed in the segmented sweep setup FREQ BASE SETUP or INDEX BASE SETUP menus and tableau dialog boxes.
• Frequency-Based Segmented Sweep:
• FREQ BASE SETUP Menu
• MAIN | Sweep Setup | SWEEP SETUP | Sweep Types = Segmented (Freq) | Freq-based Seg. Sweep Setup | FREQ BASE SETUP
• Index-Based Segmented Sweep:
• INDEX BASE SETUP Menu
• MAIN | Sweep Setup | SWEEP SETUP | Sweep Types = Segmented (Index) | Index-based Seg. Sweep Setup | INDEX BASE SETUP
Sweep Type Power-Based
If Sweep Type = Power Sweep (CW Frequency) or Power Sweep (Swept Frequency):
• The POWER SETUP has nine (9) buttons.
• Available buttons are: Port Selection, Single Power Mode (ON/OFF), Single Power (dBm), Effective Single Power (dBm), Attenuators, Power Cal, Receiver Cal, Port Power (Coupled/Not Coupled), and External Source Power.
• Note that these buttons have moved from the POWER menu to the POWER SETUP Attenuators, Power Cal, Receiver Cal, Port Power (Coupled/Not Coupled), and External Source Power.
• Power-Based CW Frequency Sweep:
• SWEEP TYPES Menu
• MAIN | Sweep Setup | SWEEP SETUP | Sweep Types = Power Sweep (CW Freq)
• Power-Based Swept Frequency Sweep:

POWER SETUP Menu - Frequency-Based Sweep - 4-Port VNAs 
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.
Apply Slope [All Ports]
Select toggles the Apply Slope value set below between off and on.
Slope (dB/GHz)
Select displays the Single Power field toolbar and allows the user to select the single power level in dBm.
Port Power (Coupled/Not Coupled)
The Port Power button toggles whether power adjustments to Ports 1-2 and Ports 3-4 are coupled or not coupled.
If Not Coupled is selected:
• The power level of the two port pairs can be adjusted separately on the POWER and POWER SETUP menus.
• The Port Selection button (described above) toggles between Port 1 and Port 2 also changing the POWER SETUP menu name between POWER SETUP [1] and POWER SETUP [2].
• The POWER menu name also changes between POWER [1] and POWER [2].
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.
• The POWER SETUP menu name changes to POWER SETUP [C].
• The POWER menu name changes to POWER [C].
• Coupling does not affect attenuator settings.
POWER SETUP Menu - Segment-Based Sweep - 4-Port VNAs
The POWER SETUP menu is not available if sweep is set to a frequency-based or index-based segment sweep. Instead, power configuration is on a per-segment basis and is configured at the FREQ BASE SETUP or the INDEX BASE SETUP menus.
