command: [:SOURce[n]][:CHANnel[m]]:POWer[:LEVel]:RISetime[l]
syntax: [:SOURce[n]][:CHANnel[m]]:POWer[:LEVel]:RISetime[l]<wsp><value>[NS|US|MS|S]
description: Sets the laser rise time of the chosen source.
parameters: Any value in the specified range (see the appropriate User's Guide).
Also allowed are:
Use [l] to set the risetime of the upper or lower wavelength laser source of a dual-wavelength laser source or a return loss
module with an internal dual-wavelength laser source. The default value of [l] is 1, the lower wavelength source. The upper
wavelength source is denoted by 2.
response: none
example: sour2:pow:ris 10ns
affects: Fixed-wavelength laser sources (Fabry-Perot, DFB lasers), return loss modules containing an internal source, and tunable
lasers, except 81602A, 81606A, 81607A, 81608A and 81609A.
command: [:SOURce[n]][:CHANnel[m]]:POWer[:LEVel]:RISetime[l]?
syntax: [:SOURce[n]][:CHANnel[m]]:POWer[:LEVel]:RISetime[l]?<wsp>[MIN|DEF|MAX]
description: Returns the laser rise time of the chosen source.
parameters: Also allowed are:
Use [l] to query the risetime of the upper or lower wavelength laser source of a dual-wavelength laser source or a return loss
module with an internal dual-wavelength laser source. The default value of [l] is 1, the lower wavelength source. The upper
wavelength source is denoted by 2.
response: The rise time as a float value in seconds.
example: sour2:pow:ris?
affects: All laser sources, DFB sources, and tunable laser modules and return loss modules with an internal source

MIN: minimum programmable value
MAX: maximum programmable value
DEF: This is not the preset (*RST) default value but is half the sum of, the minimum
programmable level and the maximum programmable level
MIN: minimum programmable value
MAX: maximum programmable value
DEF: This is not the preset (*RST) default value but is half the sum of, the minimum
programmable level and the maximum programmable level
