Mixed Signal Oscilloscopes (MSO’s for short) feature the ability to
show both analog and digital signals using the same timebase. In this
way, you can more accurately determine the timing of digital and analog
events.
The SIGLENT 4 channel SDS1004X-E series of oscilloscopes (currently the 100 MHz SDS1104X-E and 200 MHz SDS1204X-E models) can be upgraded to include the ability to measure up to 16 digital/logic channels. This allows the user to conveniently view up to 4 analog (8-bit resolution) and 16 digital (1-bit resolution) channels on the same timebase which can quickly correlate analog and digital events.
