STANDARD TOOLS FOR ADVANCED ANALYSIS
History Mode Waveform Playback
Scroll back in time using History Mode to view previous waveforms and isolate anomalies. Use cursors and measurement 
parameters to quickly nd the source of problems. History mode is always available with a single button press, no need to 
enable this mode and never miss a waveform.
Go Back in Time to Identify the Source of a Problem
Advanced Math and Measure
With many math functions and measurement 
parameters available, the HDO4000A can measure and 
analyze every aspect of analog and digital waveforms. 
By utilizing HD4096 technology, the HDO4000A 
measures 16 times more precisely than traditional 8-bit 
architectures. Additionally, the HDO4000A provides 
statistics, histicons and trends to show how waveforms 
change over time.
WaveScan Advanced Search
WaveScan provides powerful isolation capabilities 
that hardware triggers can’t provide. WaveScan allows 
searching analog, digital or parallel bus signal in a single 
acquisition using more than 20 different criteria. Or, set 
up a scan condition and scan for an event over hours or 
even days.
