Set pulse times
DELay <n>
:SOURce[1]:PULSe:DELay <n> Set current source pulse delay
Parameters
<n> = 20e-6 to 0.5 Specify pulse delay in seconds
MINimum 20e-6 seconds
MAXimum 0.5 seconds
DEFault 10e-3 seconds
Query
:DELay? Query pulse delay
:DELay? DEFault Query *RST default pulse delay
:DELay? MINimum Query lowest allowable pulse delay
:DELay? MAXimum Query highest allowable pulse delay
Description
This command is used to set the delay time between current pulses in
the pulse function. It sets the pulse delay in the fixed and sweep modes,
but it does not control pulse delays for the list mode, which are pro-
grammed separately (see
“Configure list,” page 14-41 ).
WIDTh <n>
:SOURce[1]:PULSe:WIDTh <n> Set current source pulse width
Parameters
<n> = 500e-9 to 5e-3 Specify pulse width in seconds
MINimum 500e-9 seconds
MAXimum 5e-3 seconds
DEFault 10e-6 seconds
Query
:WIDTh? Query pulse width
:WIDTh? DEFault Query *RST default pulse width
:WIDTh? MINimum Query lowest allowable pulse width
:WIDTh? MAXimum Query highest allowable pulse width
Description
This command is used to set the current pulse width in the pulse func-
tion. It sets the pulse width in the fixed and sweep modes, but it does not
control pulse widths for the list mode, which are programmed separately
(see
“Configure list,” page 14-41 ).
TRANsition[:STATe] <b>
:SOURce[1]:PULSe:TRANsition:STATe <b> Control pulse transition control state
Parameters
<b> = 0 or OFF Disable transition control
1 or ON Enable transition control
Query
[:STATe]? Query state of transition control
Description
This command enables or disables pulse transition (rise time) control.
When off (0) the leading edge is as fast as the system hardware allows.
When on (1), the turn on is intentionally slowed down to a fixed setting
of 5e-6. (The output will not fully settle to its final value for 5
µ
s.)
