Dependent Measurements

User-defined measurements can use the results of standard Infiniium measurements which, in this context, are called dependent measurements.

Dependent measurements that will be used in a user-defined measurement are identified using the <Dependent> element in the configuration XML file. See <Dependent> Element.

The dependent measurements that are available depend on the type of data being measured, as identified by the <ValidType> element in the configuration XML file. See <ValidType> Element.

When measuring waveform data, these dependent measurements are available:

• Amplitude
• Waveform Base (or Base)
• Maximum
• Minimum
• Peak-Peak (or Peak-Peak Amplitude)
• Time at Max
• Time at Min
• Waveform Top (or Top)
• Amplitude at Lower (or Ampl at Lower)
• Amplitude at Middle (or Ampl at Middle)
• Amplitude at Upper (or Ampl at Upper)
• Effecitve Bits

When measuring NRZ eye data, these dependent measurements are available:

• Eye Amplitude (or Eye Ampl)
• Bit Rate
• Crossing %
• Database Peak Hits (or Peak Hits)
• Crossing Time
• Signal to Noise Ratio (or SNR)
• Eye Fall Time
• One Level
• Eye Rise Time
• Zero Level

When measuring PAM eye data, these dependent measurements are available:

• Noise Margin (rms)
