Agilent 86038B Photonic Dispersion and Loss Analyzer, Second Edition
IF Bandwidth
This control sets the bandwidth of noise-reducing filter circuitry
and algorithms in the RF network analyzer. A lower value of IF
Bandwidth provides better noise rejection but also increases
measurement time. For the same impact on measurement time,
reducing IF bandwidth is more effective in suppressing noise
than increasing the samples/point.
TLS Power
This control sets the TLS output power limit. The default value
of +5 dBm is available from the 81600B-160 tunable laser
source, for example, from 1520 nm to 1610 nm. For other
tunable laser sources refer to the individual TLSspecification.
At higher TLS power levels, Amplitude Dynamic Range and
Group Delay Noise is improved, but phase dynamic accuracy
(PDA) effects are more pronounced. After changing the TLS
power, normalization (without PDA) is required.
The 86038B will automatically choose the highest TLS power
available over the chosen wavelength range, but the power limit
can be used to reduce the chosen power, for example to avoid
power changes when the wavelength range is changed. It can
also be used when measuring amplifying devices to avoid
exceeding the safe power to the optical receiver.
