    Menu 2.13 Ratio Setup This setting has the effect of scaling the measured value of the current and voltage. For example, a 116V signal becomes 232V when the “Voltage Ratio” is set to 2. The Ranges are not effected by this setting, so the 150V range is still shown and used.

  • Page 23: Measurement Setup

    Measurement Setup Central to setting the proper range of the instrument is the Crest Factor. Crest factor is the ratio of the peak value of a waveform to the RMS value of the waveform. For example, a perfect sine wave crest factor RMS value is 0.707*Peak. The crest factor is the inverse of the normalized RMS value, 0.707 = 1.414.

  • Page 30: Waveform Display Function

    Waveform Display Function The 5335B power meter displays waveform representations of the sampled data measured. This function is designed to be similar to an oscilloscope with many of the typical functions of oscilloscopes available, like trigger, run/stop and single trigger. The capture of data is not limited to that displayed onscreen, the measurement interval is also involved. For example, measuring a 15Hz signal with the interval set to 0.1s does not allow for stable measurement of the frequency.
