There are eleven module slots in the TG 2000 Signal Generation Platform. The
Clock and CPU modules are required for system operation and permanently
occupy two special slots (they must be installed in these slots). The black burst
module (BG1 Generator module) is also a standard component of the TG 2000
Signal Generation Platform, but you can remove it or replace it with another
module if desired. Without the black burst module, optional genlock or GPIB
modules, there is room for nine generator modules. You can use any combination
of different generator modules and/or multiples of the same generator module.
Generator modules, except the black burst module, contain NVRAM for storing
test signals. The test signals are initially loaded from the supplied disks or
through the parallel, GPIB, or RS-232 port into NVRAM. The signal that is
selected for output is loaded into fast memory on the module. The loaded signal
configures the module to immediately output the selected signal. The flexible
memory architecture allows one generator module to output signals stored on
another module of the same type. For example, installing four AVG1 Generator
modules provides four times the signal storage space, and all four modules have
equal access to this expanded memory space.
