The Model K100-D/32 Input Adapter (see Figure 1.1) transforms the Model K100-D Logic Analyzer from a 16-channel timing and data domain instrument into a 32-channel data-do- main-only instrument. In addition to the extra channels provided by the adapter, it also provides user selectable circuitry necessary for extensive OR clocking and demultiplexing capabilities to match the needs of the most advanced microcomputers. The accessory connects directly to the K100-D front panel inputs. The K100-D automatically senses the presence of the adapter, and executes a branch to the appropriate firmware subroutines for 32-channel operation. Both the video display and the keyboard operation of the K100-D change to reflect the new record parameter options available in this mode. These changes include: (1) reconfiguration of the data memory from 1024 16-bit words into 512 32-bit words; (2) using the Enable field as the 16-bit fixed sequence address portion of the trigger word; (3) using the Trigger field as the 16-bit variable sequence data portion of the trigger word; and (4) extending the search mode to 32 bits. This accessory was especially designed to provide a flexible signal conditioning enclosure for use with the Model K100-D/32 Input Adapter. You can simplify system connection and eliminate the need for individual probe leads by wire wrapping the test signal connections inside the enclosure. Also, the accessory has space for adding active pre-processing circuitry and gives direct access to all test signals to facilitate parallel testing.
