[:SOURce[<n>]]:PULSe:WIDTh
Syntax [:SOURce[<n>]]:PULSe:WIDTh {<seconds>|MINimum|MAXimum}
[:SOURce[<n>]]:PULSe:WIDTh? [MINimum|MAXimum]
Description Set the pulse width of the specified channel.
Query the pulse width of the specified channel.
Parameter Name Type Range Default
[<n>] Discrete 1|2 1
<seconds> Real 16ns to 999.999 982 118 590 6ks 500us
Explanation  The pulse width is defined as the time interval between 50% of the amplitude
of a pulse rising edge to 50% of the amplitude of the next pulse falling edge.
 The range of the pulse width is limited by the “minimum pulse width” and
“pulse period (for the ranges of the “minimum pulse width” and “pulse period”,
please refer to the “Signal Characteristics” of the “Specifications” in DG1000Z
User’s Guide ). The actual range of the pulse width is

P —— pulse period.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related
parameters of CH1 by default.
Return Format The query returns the pulse width in scientific notation with 7 effective digits, for
example, 1.000000E-02 (the pulse width is 10ms, namely 0.01s).
Example :SOUR1:FUNC:PULS:WIDT 0.01 /*Set the pulse width of CH1 to 10ms (namely
0.01s)*/
:SOUR1:FUNC:PULS:WIDT? /*Query the pulse width of CH1 and the query
returns 1.000000E-02*/
