• Value of t
t indicates the gain tilt.
t = xx.xx in dB units to two decimal places
• Value of SP
SP indicates the spacing of the specified peak.
SP = xxxx.xxx in nm units to three decimal places
• Value of Spf
SPf indicates the value of the spacing frequency of the specified peak.
SPf = xxxx.xx: Outputs values in fixed GHz units to two decimal places.
The spacing data for m = 1, however, does not exist, thus, outputs SPf = 0.
• Value of Rλ
Rλ indicates the relative wavelength of the specified peak.
Rλ = xxxx.xxx in nm units to three decimal places.
• Value of RL
RL indicates the relative level of the specified peak.
RLk = xxxx.xx in dB units to two decimal places.
When there is no data each of the above returns wavelength l = –1, and Level L =
–999.99.
