The R&S NGL/NGM displays the device/channel menu window.
2. Select the required channel tab to apply constant resistance.
The R&S NGL/NGM displays the selected channel menu.
3. Select the "Constant Resistance" from the menu.
The R&S NGL/NGM displays the "Constant Resistance" dialog.
4. Activate the "Enabled" menu item.
When operates in sink mode condition, the R&S NGL/NGM displays the "Constant
Resistance" icon on the selected channel status bar information.
5. Set the required resistance.
The R&S NGL/NGM displays the on-screen keypad to set the value.
6. Confirm value with the unit key (mΩ or Ω).
The value for "Constant Resistance" is rounded to the nearest 1 Ω or 0.1 Ω,
