Recall File
You can recall a previously saved measurement or setup or a screen shot file either from the instrument internal memory or from a removable USB drive. Only one file of any type can be recalled at a time.
Recalling a measurement or setup may change the current instrument settings and turn off any calibration correction. Consider saving the current setup before recalling a file.

Recalled Measurement and Active Trace
The recalled measurement is the purple trace and is overlaid on the current active (yellow) trace. In Figure: Recalled Measurement and Active Trace, the recalled measurement is used to compare the cable loss of two different RF cables. Recalled measurements are automatically saved to trace memory for use in trace match functions. To see the recalled measurement and the current measurement simultaneously, select Trace & Memory in the Trace Display submenu. Refer to Trace.
