This command is used to set the delay of the second pulse, from the time of the trigger, in the
double pulse mode. It has exactly the same effect as the :PULSE:DELAY command, and is
included in the command set for compatibility purposes.
COMMAND TYPE: Setting or Query
SETTING
Syntax: [:SOURce]:PULSe:DOUBle:DELay<ws><delay>[units]
Arguments:
Type: NRf
Units: S (seconds), MS (milliseconds), US (microseconds), NS
nanoseconds
Range: 0NS to 9.80000S
Rounding: To current resolution
Examples: :PULS:DOUB:DELay 150NS
QUERY
Syntax: [:SOURce]:PULSe:DOUBle:DELay?
Examples: :PULS:DOUB:DEL?
Response: NRf
CONSIDERATIONS:
The allowed range of the delay will be determined by the values of the period, width, and
transition times.
4.12.1.17 Leading Edge Time
This command is used to set the value of the leading edge time. If the edge-tracking feature is
ON, changing the leading edge will cause the same change in the trailing edge. Refer to 2.1.19
for the tracking control command.
COMMAND TYPE: Setting or Query
SETTING
Syntax: [:SOURce]:PULSe:TRANsition[:LEADing]<ws><lead time>[units]
Arguments:
Type: NRf
Units: S (seconds), MS (milliseconds), US (microseconds), NS
nanoseconds
Range: 5NS to 10MS
Rounding: To current resolution
Examples: :PULS:TRAN:LEAD 50NS
:PULS:TRAN 85NS
QUERY
Syntax: [:SOURce]:PULSe:TRANsition[:LEADing]?
Examples: :PULS:TRAN:LEAD?
Response: NRf
CONSIDERATIONS:
The allowed value of the leading edge time is limited by the values of the period, width
and delay. In addition, the ratio between the transition times is limited to a maximum of
20:1, and both transition times must be in one of the following ranges:
5ns to 100ns
50ns to 1 us
500ns to 10us
5us to 100us
50us to 1ms
500us to 10ms
