difference between digitizer,DAQ and digital Oscilloscope
This page compares digitizer,DAQ and digital oscilloscope and provide difference between digitizer,DAQ and digital Oscilloscope.
Before we proceed for comparison between digitizer and DAQ systems refer digitizer basics.
|Sampling type||Simultaneous sampling||mostly multiplex sampling is used, simultaneous sampling is rarely used|
|Sampling rate||higher, typically 20MSPS and above||Lower, typically 10MSPS or less|
|Timing circuit||More accurate||Less accurate|
|Additional functionalities||Few digital I/Os||Digital I/O channels, analog I/O channels, counters/timers|
|Rearm time (Referred as timing between two triggers)||Faster||Slower|
|Vertical range (referred as input voltage range which can be measured)||Wider, upto 50V||Smaller, about 10V|
Following are the difference between Digitizer and digital Oscilloscope.
|Onboard processing capability||Limited||Better|
|Waveform analysis||Data acquired can be offline analyzed w.r.t. various parameters||Rich set of functions like multiple triggering options, waveform analysis, advanced signal acquisition|
|User interface(UI)||Poor UI||Better UI|
|Cost of Ownership||Lower||Higher|
|Integration||Better with systems providing external processing compare to oscilloscope||-|
|Application||Large data processing, refer basics of data loggers||Troubleshooting|
