Table B- 1: Pulse Measurements — Amplitude (cont.)
Name Definition
Gain The amplitude gain between two waveforms . T he measurem ent ret urns the ratio between the
amplitudes measured wit hin the measurem ent regions of t he two sources.
Where Amplit ude1 and Ampl itude2 are the Amplitude measurements of the two source
waveforms. See Amplitude on page B--2.
If enabled, measurement gates constrain the measurement region to the area between the Start
Gate (G1) and Stop Gat e (G2) of t he two sources. See To Localize a Measurement on
page 3--83.
For best results with this measurement, optimize the vertical resolution before taking this
measurement. See To Optimize the Vertical Resolution on page B--69.

High The top reference level for a measured waveform. Several methods can be applied to t he data
sampled in the upper half of the waveform to determine the High value. You can use the
Tracking Method control to select among them. See Tracking Methods on page B--66. Also see
High/Low Tracking Method on page 3--77.
If enabled, measurement gates constrain the measurement region to the area between the Start
Gate (G1) and Stop Gate (G2).
For best results with this measurement, optimize the vertical resolution before taking this
measurement. See To Optimize the Vertical Resolution on page B--69.
Low The bottom reference l evel for a measured wavef orm. Several methods can be applied to the
data sampl ed in the l ower half of the waveform to determine the Low value, and you can use
the Tracking Method control to select among them.
If enabled, measurement gates constrain the measurement region to the area between the Start
Gate (G1) and Stop Gate (G2).
For best results with this measurement, optimize the vertical resolution before taking this
measurement. See To Optimize the Vertical Resolution on page B--69.
Max The largest amplitude peak of the waveform over the measurement region.
If enabled, measurement gates constrain the measurement region to the area between the Start
Gate (G1) and Stop Gate (G2).
For best results with this measurement, optimize the vertical resolution before taking this
measurement. See To Optimize the Vertical Resolution on page B--69.
Mean The arithmetic mean of the waveform over the measurement region.
If enabled, measurement gates constrain the measurement region to the area between the Start
Gate (G1) and Stop Gate (G2).
For best results with this measurement, optimize the vertical resolution before taking this
measurement. See To Optimize the Vertical Resolution on page B--69.
