GDS-2000E provided bus decode function; segment memory; waveform search function which not on the GDS-1000B.
For the sampling rate comparison, both series are max. 1GSa/s.For GDS-2000E series ,the max. sampling rate will keep 500MSa/s for 4CH activate and 2CH activate will keep 1GSa/s. However, for GDS-1000B series, the max. sampling rate will reduced to 250MSa/s for 4CH activate and 2CH activate will reduced t0 500MSa/s.
