[:SOURce[<n>]]:PULSe:TRANsition[:LEADing]
Syntax
[:SOURce[<n>]]:PULSe:TRANsition[:LEADing] {<seconds>|MINimum|MAXimum}
[:SOURce[<n>]]:PULSe:TRANsition[:LEADing]? [MINimum|MAXimum]
Description
Sets the pulse rise time of the specified channel.
Queries the pulse rise time of the specified channel.
Parameter

Type
Range
Default
[<n>]
Discrete
1|2
1
<seconds>
Real
8 ns to (0.625×pulse width)
20 ns
Remarks
 The rise time is defined as the time required for the pulse amplitude to rise from 10% to 90%.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 The range of the rise time is limited by the current waveform frequency and pulse width. When the
specified value exceeds the limits, DG2000 will adjust the edge time automatically to make it match
the specified pulse width.
Return Format
The query returns the pulse rise time in scientific notation, with 7 effective digits. For example,
3.500000E-08 (the pulse rise time is 35 ns).
Example
:SOUR1:PULS:TRAN 0.000000035 /*Sets the pulse rise time of CH1 to 35 ns.*/
:SOUR1:PULS:TRAN? /*Queries the pulse rise time of CH1 and the query returns
3.500000E-08.*/
[:SOURce[<n>]]:PULSe:TRANsition:TRAiling
Syntax
[:SOURce[<n>]]:PULSe:TRANsition:TRAiling {<seconds>|MINimum|MAXimum}
[:SOURce[<n>]]:PULSe:TRANsition:TRAiling? [MINimum|MAXimum]
Description
Sets the pulse fall time of the specified channel.
Queries the pulse fall time of the specified channel.

Remarks
 The fall time is defined as the time required for the pulse amplitude to fall from 90% to 10%.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 The range of the fall time is limited by the current waveform frequency and pulse width. When the
specified value exceeds the limits, DG2000 will adjust the edge time automatically to make it match
the specified pulse width.
Return Format
The query returns the pulse fall time in scientific notation, with 7 effective digits. For example,
3.500000E-08 (the pulse fall time is 35 ns).
