RF Output Level Accuracy and Flatness

This topic page applies to the E5071C using the Factory Recommended Variant test plan.

This test checks the level accuracy and frequency flatness of the ENA test port output signal. The level accuracy is checked for an output power level setting of 0 dBm for E5071C ≤ 8.5 GHz or –5 dBm for E5071C > 8.5 GHz at 50 MHz using a power meter. The frequency flatness is tested by measuring the power level at several frequency points from 9 kHz to 20 GHz (depending on the option) and calculating the differences between them and the power meter reading at 50 MHz.

  1. The DSG (Device Substitution Group) is listed below the equipment description, if applicable. These devices are required to be mapped in TME to execute a test. DSGs require either GPIB communication or are important for dynamic measurement uncertainty calculations. N/A refers to required equipment that is not mapped as DSGs in TME.
  2. Refer to the main Required Test Equipment for a list of alternative models.

Connection Setups
  • Due to the complexity of the ENA family of analyzers, only a single representative model will be shown.
  • Some images may not apply to all models.
