    The data timing generator has two types of channels: logical and physical. Logical channels represent one-bit width pattern data. The number of logical channels is 32 (4 channels x 8 slots) for DTG5078, or 8 (2 channels x 4 slots) for DTG5274 and DTG5334.
  • Page 27 The number of logical channels that the system can accept is determined by the mainframe (32 for DTG5078, 8 for DTG5274, and 8 for DTG5334). In the Master-Slave operation mode, the number increases with the number of mainframes.
