Table B- 7: NRZ Measurements - Amplitude (cont.)
Name Definition
NRZ Mid The middle level between the Max and Min verti cal values of the selected waveform within the
measurement region.
Where Max and Mi n are the maximum and minimum measurements.
If enabled, measurement gates constrain the measurement region to the area between the Start
Gate (G1) and Stop Gate (G2). See To Localize a Measurement on page 3--83.
When this measurement is turned on, it will automatically set the measurement system to use a
waveform database if available. See Use a Waveform Database on page B--70.
For best result s with t his measurement:
H Perform a Dark Level compensati on before taki ng this m easurement if the source of the
measured waveform is an optical channel. See To Perform Dark-Level and User
Wavelength Gain Compensations on page 3--98.
H Optimize the vertical resolution before taking this measurement. See How to Optimize the
Vertical Resolution on page B--70.
