Table B- 4: RZ Measurements - Amplitude (cont.)

Name Definition

RZ Min The minimum 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 Peak-to-Peak The difference between the Max and Min vertical values of t he waveform t hat is sam pled within

the measurement region.

RZ Peak-to-Peak = Max – Min

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 M easurem ent 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.
