Same Square Wave on HP 54645D
The maximum and minimum values are displayed in additional to some
normal samples. The additional normal samples here give you a better
understanding of the actual waveform by showing you the signal transitions
in addition to the maximum and minimum values.
Changing Display Modes While Stopped
One of the benefits of the HP 54645A/D is that you can change display modes
after you acquire data. You can switch from peak detect to normal display mode.
If you acquire data in normal mode, then switch to peak detect, you will see all
the peaks in memory. However, you are not guaranteed to see every 5-ns peak.
This allows you to view the data differently, without having to re-acquire the
information.
Using Peak Detect and Autostore
Peak Detect includes both normal and peak detect samples. Using Peak Detect
and Autostore together is a powerful way to find spurious signals and glitches.
