Measurement Operations & Settings Signal Generation The SOURce Subsystem
126 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
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: 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 pro -
grammable level
NOTE Use [l] to set t he riset ime of t he uppe r or low er wave length laser s ource o f a dual -wavele ngth
laser source or a return loss module with an int ernal dual-wavelength laser source. The de-
fault value of [ l] is 1, the lower wavelength source. The upper wavelength source is denoted
by2.
response: none
example: sour2:pow:ris 10ns
affects: All laser sou rces, DFB sources, and tunable laser mod ules and return loss modules with an
internal source
command: [:SOURce[ n]][:CHANnel[m]]:POWer[:LEVel]:RISetim e[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: 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 l evel and the maximum pro-
grammable level
NOTE Use [l] to query the risetime of the upper or lower wavelength laser source of a dual-wave-
length laser source or a return loss module with an internal dual-wavelength laser source.
The default value of [l] is 1, the lower wavelength sourc e. The upper wave length source is
denoted by2.
response: The rise time as a float value in seconds.
example: sour2:pow: ris? +1.00000000E-00 9<END>
affects: All laser sourc es, DFB sources, and tunable laser modul es and return loss modules with an
internal source
