DL850EV

The Yokogawa DL850EV is the Vehicle Edition of the DL850E ScopeCorder, a portable instrument that combines a mixed-signal oscilloscope with a long-duration data recorder. It has eight slots for plug-in modules, chosen from about 20 types (high-speed isolated voltage up to 100 MS/s, high-resolution voltage, temperature, strain, acceleration, frequency, logic), each with individually isolated inputs.

The Vehicle Edition adds features for automotive and railway work: CAN, CAN FD, LIN and SENT monitor modules can only be used in the DL850EV, which then handles up to 120 channels per slot and 336 channels per unit, and decodes bus data with DBC/LDF symbol files so it can be shown as trends next to analog sensor signals. The /DC option lets it run from a 12 V vehicle battery (10-18 V) with automatic switchover between AC and DC.

Acquisition memory is 250 M points as standard (1 G or 2 G with /M1 or /M2), with real-time recording to an optional internal 500 GB hard disk or a PC for up to 200 days. Options include a built-in 112 mm printer, GP-IB, IRIG or GPS time inputs and real-time power math (/G5). Yokogawa discontinued the DL850E/DL850EV on 26 August 2021 and names the DL950 as the replacement; Xviewer software is used for analysis on a PC.
