Follow the steps below to confirm the results of the DUT’s frequency transient (Wide Band) measurement, using the E5052B’s transient measurement window.
Press the Trace Next key to select the measurement trace for the frequency transient (Wide Band). You can confirm which trace is selected by viewing the cursor displayed to the left of the trace title.
You can also click on the measurement trace of the frequency transient (Wide Band) for confirmation.
You can select the unit (frequency format) used in the frequency trace screen and set the sensitivity aperture.
Press Format > Frequency Format.
Select an appropriate frequency format from the softkey menu list. The available options are as follows. The initial setting is "Hz."
