The Keysight (Agilent) 1660ES is a 136-channel benchtop logic analyzer built for timing and state analysis of complex digital systems. It captures high-speed digital events at up to 500 MHz in timing mode (half-channel configuration) and delivers 100 MHz state analysis across all channels. The integrated 2-channel oscilloscope with 2 GS/s sampling and DC to 250 MHz bandwidth provides simultaneous analog visibility into digital signals, enabling rapid isolation of signal integrity issues and timing violations.
