Remote Control User Guide for the MX / MBX / TLX1 / TLX2 Series Chapter 2: Supported Commands
Rev. E, May 5, 2022 Page 13
2.5. System Commands
The system commands described in this section apply to all MX / MBX / TLX1 / TLX2 instrument Item #s. The LED
brightness commands given below allow the user to either individually set the brightness of the red, green, and blue
LEDs or to set the brightness of the White LED which is a combination of the red, green and blue LEDs being
controlled at the same level automatically, that contribute to the under-chassis lighting integrated into the housings
of these instruments. The brightness can be set using a scale from 0.0 to 1.0, and the default combination is a value
of 0.0 for the red LEDs, 0.0 for the green, 0.75 for the blue, and 0.75 for white. These LEDs can be used to provide
a visual indicator of a change in instrument status. For example, the lighting could be changed to green to indicate
the conclusion of a test driven by remote-control commands.

nm. This command sets the system wavelength, which is used to
selected which calibration values to use when configuring the
VOA and when evaluating the power measurements made at the
taps. Setting the system wavelength optimizes the instrument for
use at that wavelength. Setting this value is equivalent to using
the touchscreen GUI to set the system wavelength.
