Advantest Q8382

The Q8382 Optical Spectrum analyzer employs a grating spectral system which is composed of Q8381 and Q83811 preselector.

The Q8382 is ideal for spectrum analysis such as DFB laser diode. The grating spectral system permits 50dB of wide dynamic range to be obtained at a location of 5mm from the peak wavelength, and 40dB at 1nm.

When the Q83811 optical preselector is used, a dynamic range of 60dB at 1nm away from a peak wavelength and 50dB at 0.5 nm can be obtained.

The Q8382 have high grating drive system and high speed processing system which provides measurement time of 1 or less seconds at 50nm span LOG indication.

One-Touch Measurement of Spectrum Pulse Duration for three types of definitions. This optical spectrum analyzer permits one-touch measurement of pulse duration with reference to three types of definition: XdB, RMS, and ENVELOPE methods.

The automatic function is provided for setting the wavelength and level to optimum values corresponding to input signals.

The measurement spectrum peak is detected automatically, and its wavelength and level are always displayed.

The Cursor function allows two cursors to be used, for the wavelength axis and level axis, and not only simple wavelength and level of screen data but also difference in wavelength and level can be read easily.

The built-in high speed thermal printer, with printing speed of ten seconds or less, permits measurement data to be recorded.

The Q8382 is equipped with a fully remote GP-IB, so it is ideal as an automatic measurement system component. Measurement data can be output directly to the plotter by using this GP-IB.

The Q8382 should not be used in locations subject to dust, direct sunlight, and corrosive gas.

The Q8382 optical spectrum analyzer has built-in cooling fans to prevent the internal temperature rising.

The internal structure of Q8382 is designed so that accurate values are obtained only when it is used horizontally.
