State the difference between CRO and DSO.
CRO
|
DSO
|
Direcly reads analog voltage and displays it on screen.
|
It reads the analog voltage and converts it into digital form before being displayed on the screen.
|
Do not require ADC, microprocessor and acquision memory
|
Requires ADC, microprocessor and acquisition memory
|
Can only analyze signal in real time as there is no storage memory available.
|
Can analyze signal in real time as well as can analyze previously acquired large samples of data with facility of storage available.
|
Can not analyze high frequency sharp rise time transients
|
Can analyze high frequency transients due to advanced DSP algorithms available and ported on microprocessor which can operate on stored samples of input voltage.
