Table B- 4: RZ Measurements - Amplitude (cont.)
Name Definition
RZ Max The maximum vertical value of the waveform that is sampled within the measurement region.
If enabled, measurement gates constrain the measurement region to the area between the Start
Gate (G1) and Stop Gate (G2).
When this measurement is turned on, it will automatically set the measurement system to use a
waveform database if available.
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 To Optimize the
Vertical Resolution on page B--69.
RZ Mean The arithmetic mean of t he wavef orm t hat is sampled within the measurement region.
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

H Optimize the vertical resolution before taking this measurement. See How to Optimize the
Vertical Resolution on page B--70.
RZ Mid The middle level between the Max and Min vertical values of the waveform that is sampled
within t he measurem ent regi on.
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).
