Brief Description

The Q8383 is an advanced spectrum analyzer (Advantest) with a two-pass monochromator and very low polarization dependence.

Thanks to a special method, values of ±0.05 dB are guaranteed, with typical values as low as 0.02 dB.

Together with the high accuracy of the resolution bandwidth, the Q8383 can be used to perform precise power measurements.

All of these features make the Q8383 an ideal measurement instrument for erbium-doped fiber amplifiers (EDFAs).

By simply comparing the signal at the input of the amplifier with the signal at the output of the amplifier,

special measurement functions can be used to determine the noise figure, gain and spontaneous emission.

Of course, all these functions are also of great advantage when measuring laser diodes, light emitting diodes and other light sources.

The curve fitting function directly displays electroluminescence characteristics by fitting a Gaussian distribution to the emission spectrum.

This is very useful for measuring Erbium Doped Fiber Amplifiers (EDFA) and Light Emitting Diodes.

A special feature for pulsed light allows measurements of fiber optic rings and soliton transport systems. Internal or external triggering is possible.

Measurement time is 0.8 seconds for a span of 200 nm and varies with the span.

Broadband light sources with a resolution of 5 nm have the highest sensitivity, 

while narrowband light sources (lasers) can be reliably analyzed down to the noise level even with a narrow resolution bandwidth.

The normalization function combined with the white light source allows direct measurement of transmission and loss characteristics of filters and fibers
