2x Averaging in Bypass Mode

This mode uses internal averaging to provide better noise performance at the tradeoff of higher power consumption and frequency response flatness.

Procedure

  1. In the bypass mode box of the GUI, make sure that the settings match those shown in Figure 3-4.

                            Settings Figure 3-4 Bypass Mode Settings
  2. Once these settings are verified, press the Device Bringup button.
  3. Wait until after the message Device Bringup Completed appears in the Log.
  4. Under the Analog and Clock tab, toggle Dither Enable to the off position.
  5. In HSDC Pro, press the Capture button. A screen appears, similar to Figure 3-5.
  6. Adjust signal generator output such that the measured fundamental power in HSDC Pro is at the user's desired level. (shown below is -12 dBFs)
