Theory of Operation This section describes the electrical operation of the AWG510 and AWG520 Arbitrary Waveform Generator of the major circuit blocks or modules. Refer to Figure 9–1 while reading this text. Module Overview The AWG510 and AWG520 are portable dual–channel waveform generator (differential for the AWG510 and single–ended for the AWG520). The waveform generator reads the digital waveform data loaded into its waveform memory. The point rate clock determines the rate at which the data is read.
Theory of Operation Analog Processing (A71/A72, Analog Output Board) This functional block amplifies the DAC analog signals to the specified output level. The input signals may pass through the low–pass filters and attenuators in this block. If an offset is specified, the Offset circuitry will add it. This board also has an adder circuitry for adding the signal from the A75 Noise Generator board or the Add Input on the rear panel to the output waveform.
Theory of Operation A30, GPIB Board. The fourth slot of the CPU Unit has the General Purpose Interface Bus (GPIB) interface driver, which controls communication with external devices over the parallel interface. The GPIB connector is on the rear panel. The GPIB Board also has the bus that sends the control signals to the Clock, AWG, and Analog Output board.
Theory of Operation Digital Data Out Option 03 The Digital Data Out option (03) directly outputs the digital data in the waveform memory without passing it through the digital-to-analog converter. This option is installed on the AWG board. For more information about options, refer to section 7, Option.
