JANUARY 1977 The 1650-D logic analyzer (LA) from Biomation provides 16 channels at 50 MHz. The 851-D provides eight channels at the same speed. Accessories can give you a logic-state display of any 16 stored words, hex or octal translation, and a vector map of memory contents. The eight- and 16-channel LAs feature pretrigger and delayed-trigger recording, a latch-record mode for fast-pulse capture, combinational true or false triggering, and a movable display cursor that stays with the data when you switch display modes.
