Keysight 81160A - Pulse Width

Features and Functions
81150A and 81160A User’s Guide 143
3.4.2 Pulse Width
Introduction
Pulse Width refers to the start of leading edge to start of trailing edge.
In this format, the pulse-width is independent of changes in pulse period
and delay.
The Pulse Width can be specified as:
 Width in seconds
 Duty Cycle (percentage of period)
 Trail Delay
Pulse Width
Characteristics
 Pulse width: Wmin to 950000s (see restrictions below). The default
pulse width is 50ns.
 The Pulse width is limited by the minimum possible width of Wmin.
 Pulse Width  Wmin
 Pulse Width  Period  Wmin
81150A: Where Wmin is either 4.1ns or 10ns depending on the
selected amplifier (See section Amplifier Type Selection).
81160A: Where Wmin is 1.5 ns.
Front-Panel
Operation
After selecting the pulse function, press the Width/Duty Cycle/Trailing
Delay softkey. Then use the knob or numeric keypad to enter the desired
pulse width.
Width in Seconds
The absolute pulse width measured from the start of the leading edge to the
start of the trailing edge. In this format, the pulse width is independent of
changes in pulse period and delay.
Duty Cycle
The duty cycle is the pulse width measured from the start of the leading
edge to the start of the trailing edge expressed as a percentage of the
period. In this format, if you adjust the period, the absolute width is adjusted
to maintain the duty cycle.
