Not exactly, no. The new Saleae products are logic analyzers with analog data logging, not mixed signal oscilloscopes.
The Analog inputs on the new Saleae products are lower bandwidth than oscilloscopes, they do not have variable gain and shift inputs, meaning that the input voltage range is fixed, and they do not support analog triggering or real time view.
However, it could be much better than an oscilloscope for many applications – especially applications where a microcontroller is interacting with an analog signal in some way, such as reading an analog voltage or controlling an analog voltage.
Logic is not a good fit for the following applications:
- signal integrity work
- high-bandwidth analog signals
- small voltages at high resolution (such as less than 100mVpp)
- analog voltages outside the range of 0-5V (Logic 4, Logic 8) or -10V – 10V (Logic Pro 8, Logic Pro 16).
