IGENPW
Description The IGENPW command selects the pulse width of the optical spectrum analyzer's current source. Use IGEN to turn on the current generator.
Normally, the current source is set for a steady dc state. You can set the pulse width from 1.0s to 6.5 ms. Use IGENDTYCY to set the pulse's duty cycle.
If VB is modied after IGENPW and IGENDTYCY command values are set, use the MSG command to conrm that the UNCAL message is not present, indicating that the amplitude measurement is valid.
