Table B- 2: Pulse Measurements - Timing (cont.)

Name Definition

+Width The horizontal interval between the crossings of the rising and falling edges at the mid-refer-

ence level of the f irst posi tive pulse i n the measurement region.

+Width = Tcross2 – Tcross1

Where Tcross1 and Tcross2 are t he t wo consecutive horizontal crossings on the first

positive pulse.

The mid-reference level is adjustable and defaults to 50% of the pulse amplitude.

See Measurement Reference Parameters and Methods on page B--56 or in the online help. Also

see Reference Levels Method on page 3--79.

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.

-Width The horizontal interval between the crossings of the falling and rising edges at the mid-refer-

ence level of the f irst negat ive pulse in t he measurement region.

--Width = Tcross2 – Tcross1

Where Tcross2 and Tcross1 are t he t wo consecutive horizontal crossings on the first

negative pul se.

The mid-reference level is adjustable and defaults to 50% of the pulse amplitude.

If enabled, measurement gates constrain the measurement region to the area between the Start

Gate (G1) and Stop Gate (G2).
