TestProcess.Measure.Ratio.Voltage.AC.Sinewave.Delta.Frequency

A test process that measures the difference  2 sinusoidal AC sinewave signals at different frequencies while keeping the voltage level constant.  The two measured values are compared, the results can be expressed as delta volts, dB or percent of change.

These two signals are often used when calibrating flatness of a device.

Required Parameters

  • Volts
  • Frequency –
  • FrequencyRef –

Optional Parameters

  • Impedance –
  • UUT.Output – Output Name of the UUT Connecting Point

Output Value & Uncertainty

  • Volts  Measured Value – Reference Value
  • dB – 20 * Log( Measured Value / Reference Value)
  • % – Measured Value / Reference Value * 100
