Item 4 on the Display menu toggles between MAX/MIN and PEAK signal
acquisition modes.
1. Press [DSPL] [4] to change acquisition modes.
2. Toggle back and forth between MAX/MIN and PEAK several times.
Notice that the display PEAK is essentially the top of the MAX/MIN
display.
The 2715 produces an analog spectrum. In the MAX/MIN acquisition mode, the
maximum and minimum amplitudes of this spectrum are alternately sampled at
512 successive points. Plotting the two interleaved sets, of 256 points each,
produces the analog-like MAX/MIN spectrum that you see. In the PEAK
acquisition mode, the maximum amplitude only is sampled and displayed at all
512 points. The Max/Min mode has the advantage of bearing some semblance to
the analog signal and readily revealing pulsed versus constant carrier signals.
Pulsed signals cause the signal peaks to be filled in.
3. Leave the display in the MAX/MIN mode.

If you want to permanently store a spectral display, either by photographing the
screen or by plotting the display, you can first title the display. If you are plotting
the display, you can also label significant points.
1. Ensure that only the D register is active.
2. Press [DSPL] [5] to select title mode.
Item 2 reads TITLE MODE EDIT if one or more registers contain a current
sweep (as now) or TITLE MODE EDIT WFM X if only saved data is displayed
(saving a waveform also saves its title).
