DL716

The Yokogawa DL716 (model 701830) is a 16-slot portable digital scope and recorder from 1999, the 16-channel successor to the 8-channel DL708/DL708E. Each slot takes one plug-in input module, and different module types can be mixed, so one instrument can record isolated voltages, temperatures, strain and logic signals side by side. The mainframe is sold without input modules.

With the high-speed modules (701855 isolated, 701856 non-isolated) it samples at up to 10 MS/s with 12-bit resolution; high-resolution, temperature, logic and strain modules cover slower signals. Standard acquisition memory is 1 MW per channel on 4 channels (200 kW on 16), expandable to 64 MW on 4 channels (16 MW on 16) with the /M3 option. Triggering includes window, pattern, pulse-width and timer triggers across all 16 channels.

The 10.4-inch colour TFT shows up to 16 traces. Data can be saved to the built-in 3.5-inch floppy drive, an optional 3.2 GB internal hard disk (which also supports real-time recording) or an external SCSI drive, and the instrument has GP-IB, RS-232, Centronics and SCSI interfaces plus a built-in 112 mm thermal printer. It does not accept the later DL750/DL850 modules.
