SCPI command “:fetch?’ header as “WaveRefSuccess,No”.
Bugs Fixed
• SCPI command ”:System:Relative:SplitRef:Clear” option ’ALL’ was treated as a subcommand, requiring a colonbut should be an option. Users should type ”:System:Relative:SplitRef:Clear
All” to clear split calibration data.

• Wavelength offset value not applied for certain WaveRef configurations
2
FIRMWARE RELEASE 4.66.025
Firmware Release 4.67.026
New Features or Changes
• Reduced precision in X & Y axis for WaveLength Offset wizard.
• WaveReference and WaveReference Traces buttons synchronized in Special Measurement
Setup menu.

present, the only way to set offset is using the WaveLength Offset wizard or SCPI command,
:Config:Tls:Offset.
Bugs Fixed
• Linear interpolation of data, combined with significant TLS offsets, potentially are corrected
wrong since they fall outside a ’known’ wavelength range. This primarily affected wavelength data on the boundaries of WaveRef sweeps.
• WaveRef Uncorrected Data mode was left ON after closing WLOffset wizard.
• Disabling WaveRef Display Traces (Special Measurement Setup) also turned off Wavelength
referencing.

Error.
• Unable to set TLS to None if TLS previously detected.
