Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and
measuring the differences between actual and displayed power levels
(in dB), the power flatness is ± half the span between the maximum
and the minimum value of all differences.
Conditions: uninterrupted line voltage, constant power setting,
temperature within ±2 K, external modulation ON.
Measurement with optical power meter.
Power Flatness Versus Wavelength
When changing the wavelength at constant power setting and
recording the differences between actual and displayed power levels,
the power flatness is ± half the span (in dB) between the maximum
and the minimum of the measured power levels.
Conditions: uninterrupted TLS output power, constant power setting,
temperature within ±1K.
Measurement with optical power meter.
Power Linearity
When changing the power level and measuring the differences (in dB)
between actual and displayed power levels, the power linearity is ±
half the span (in dB) between the maximum and the minimum value of
all differences.
Conditions: power levels from within specified output power range,
uninterrupted TLS output power, at fixed wavelength settings and
stable temperature.
Measurement with optical power meter.
Power Repeatability
The random uncertainty in reproducing the power level after changing
and re-setting the power level. The power repeatability is ± half the
span (in dB) between the highest and lowest actual power.
Conditions: uninterrupted TLS output power, constant wavelength,
temperature within ±1 K, short time span.
Measurement with optical power meter.
NOTE The long-term power repeatability can be obtained by taken the power
repeatability and power stability into account.
