Volt/Hz format is added from the firmware revision A.03.10. The scale is linear for dBV/Hz, dBm/Hz and log for Volt/Hz. When Volt/Hz is selected, the unit of displayed result is Volt/√Hz. (The notation "Volt/Hz" is used in this help as the same as softkey label.)
Press Marker to display marker 1 on the screen.
Move marker 1 to the point you want to confirm and read the measurement value displayed in the upper part of the graph. To confirm multiple values, press Marker > Marker x (x=1 to 10), which allows you to display up to marker 10.
In this measurement, you cannot specify the sweep time. It will be determined automatically based on the selection of the offset frequency sweep range and the carrier frequency band.
