ZT452-21 VXI
Agilent (HP) E1426A Replacement Solution
The ZTEC ZT452VXI-21 is a modern VXI oscilloscope that provides extensive functionality, in most cases beyond that of the E1426A.
The main difference between the two instruments is that the Agilent E1426A is a low-sample rate oscilloscope that uses repetitive sampling to
reconstruct high-bandwidth waveforms. Whereas the ZTEC ZT452-21 provides the same reconstructive repetitive sampling, it also provides single-shot
acquisition up 1GS/s. See below for a list of the differences between the ZT452-21 and the E1426A. Note that there are no differences in other
specifications not listed in the table. Because the instrument functionality, command set, and I/O ranges are different, there is more effort
involved with the integration of the ZT452-21 in place of the E1426A. ZTEC's application engineering team has significant experience with the
functional differences between the E1426A and the ZT452-21, as well as the application details of using VXI oscilloscopes in ATE test programs.
This experience is invaluable when assisting a test system integrator in successfully modifying an existing ATE system or TPS.
