Shorter test time on the 8588A/8558A high-speed digital platform enables you to increase throughput, improve yield and realize a greater return on your investment. The 8588A/8558A digitizes to memory at 200 nanoseconds per reading and delivers 4.5-digit data to a PC via USB, Ethernet, and GPIB at 100,000 readings per second. Fast, high-resolution data capture gives you the quantity and quality of information you need to make timely, correct decisions affecting system throughput and efficiency.
The 8558A features a 5 mega-sample digitizing rate with up to 20 MHz analog bandwidth, making it the first and only instrument on the market that can characterize extremely low-level transient signals at 18-bit resolution. This capability makes it easier to debug designs, uncover anomalies and perfect your devices under test for use in real life environments.
Inserting a new instrument into a tightly synchronized system can create overhead and incompatibility. The 8558A’s digital platform includes common connectivity interfaces plus precise triggering that lets it digitize, integrate and transfer data anywhere in the system for analysis, with minimal obstruction and the highest reliability.
