  • Page 6 Preface This is the service manual for the AWG2005 Arbitrary Waveform Generator. The manual contains information needed to service the AWG2005 to the module level. Manual Structure This manual is divided into sections, such as Specifications and Theory of Operation. Further, some sections are divided into subsections, such as Product Description and Removal and Installation Procedures.
  • Page 7 Modules Throughout this manual, any replaceable component, assembly, or part of the AWG2005 is referred to generically as a module. In general, a module is an assembly (like a circuit board), rather than a component (like a resistor or an integrated circuit). Sometimes a single component is a module; for example, the chassis of the AWG2005 is a module.

    Wait for the AWG2005 to finish the operation when doing internal calibration or saving waveform or sequence files. Improper power off or unexpected loss of power to the AWG2005 can result in the corruption of data stored in nonvolatile memory.
  • Page 55: Memory Backup Power

    Memory Backup Power A lithium battery maintains internal nonvolatile memory, allowing the AWG2005 to retain waveform and sequence files if AC power is lost. This battery has a shelf life of about three years. Partial or total loss of stored information at power on may indicate that the battery needs to be replaced.

    As long as the front panel MANUAL button is pushed, (or the gating signal is high) the AWG2005 outputs the specified waveform or sequence. When the MANUAL button is released (or the gating signal goes low), the waveform output stops. When the MANUAL button is pushed again, the output resumes from the level at which the waveform or sequence output stopped.

  • Page 67 This item sets the slope for external trigger signals. To select a positive or negative slope, push the side menu Slope but ton. For a positive slope, the AWG2005 applies the trigger at the rising edge of the external trigger signal; for a negative slope, the trigger is applied at the falling edge of the external trigger signal.
  • Page 68: Theory Of Operation

    For each channel, the AWG2005 reads the digital wave form data loaded into its waveform memory. The point rate clock determines the rate at which the data is read. The AWG2005 converts the data from digital to analog format and outputs the resulting arbitrary waveform.

    Options and Accessories The skew of the data output is held to "15 ns. The rising and falling times will depend on the buffer ICs, but neither is greater than 4 ns. See Figure 7 5. This figure shows the specifications for the waveform at the output connector when a cable is not being used.
  • Page 198: Figure 7 7: Digital Data Out Cable

    Cable Option 04 comes with a digital data out cable. The cable connecting the AWG2005 rear panel output connectors and the user circuit is extremely critical for operation at the maximum clock frequency. Figure 7 7 shows the digital data out cable provided as a standard accessory and the receiving connector.
