Hint
You may want to save the current measurement state to non-volatile RAM
(NVRAM). That way, if you don't have time to finish the procedures in this
chapter, you can quickly reproduce the test signal. To do this, press
[Save/Recall] [default disk] [non-volatile RAM disk] [return] [save state]. Then enter the name
of the file you want to create and press [enter]. To recall the state, press
[Save/Recall] [catalog on] [recall state], select the file that you created, and press [enter].
