erases any data previously stored in trace C and continuously displays any
signals detected during the sweep of the spectrum analyzer. This function is
activated at power on and by pressing
(jj].
Changing the trace mode of trace C to clear write or minimum hold can change
the trace mode of trace A and trace B. If trace A or trace B is in clear-write
mode or maximum-hold mode when trace C is changed to clear write or
minimum hold, the trace mode of trace A or trace B is changed to store blank.
The following table shows the trace mode of trace A or trace B before and
after changing trace C to clear-write or minimum-hold trace mode.

If you want to use trace A or trace B in the clear-write or maximum-hold mode
and do not want trace C to blank it, use minimum-hold or view-trace mode for
trace C.
