Query Syntax

:CALibrate:OPTical:PREVious:MPOWer?

Description

When performing an optical path calibration, this query returns the measured power from the previously completed optical path calibration step. A single calibration step calibrates all possible optical paths available from a specific output lane of a fixture. The returned string identifies each optical path and its measured power output.

In the returned string:

  • Semicolons (';') delimit between the results for each optical path. For example,
    • <optical-path>;<optical-path>;<optical-path>;<optical-path>;...
  • Within an optical path, a colon (':') delimits between the path identification and its measured power (Watts). For example,
    • <path-ID>:<measured-power>;<path-ID>:<measured-power>;<path-ID>:<measured-power>;...
  • Within a <path-ID> commas (',') delimit between devices along a path with each device enclosed in brackets ('[' and ']').
    • [<device>],[<device>],[<device>],...
  • Within a <device> field, bars ('|') are the delimiter between in/out ports and device names. When a device does not have an input or output port, that field is simply missing.
    • [<in port>|<device name>|<out port>]

The following drawing shows the fields for a typical path. Note that delimiters are shown in the color red. Additional paths can be included for additional switch modules, impairments, and DWDMs.
