ZT4628 VXI
Analogic DBS907AB + DBS9905 Replacement Solution
The ZTEC ZT4628 is a modern
oscilloscope that provides extensive functionality, in most cases beyond that of the DBS907AB.
See below for a list of the differences between the ZT4628 and the DBS907AB. Because the instrument functionality, command set, and I/O
ranges are different, there is some effort involved with the integration of the ZT4628 in place of the DBS907AB.
ZTEC's application engineering team has significant experience with the functional differences between the DBS907ABA
and the ZT4628, as well as the application details of using oscilloscopes in ATE test programs. This experience
is invaluable when assisting a test system integrator in successfully modifying an existing ATE system or TPS.
