Smoothing <<See section 5.17 for the operating procedure>> This function attenuates the noise in the measured waveform. By using the Smoothing function, areas on the waveform with a large amount of noise can be “smoothed out” when measured. IM AQ6373-01EN...
Page 23 The function is used in cases such as: when the light source’s level is fluctuating; when Index measuring a modulated signal of several kHz or less; when the waveform is disrupted and difficult to measure; when it is necessary to obtain even higher measurement sensitivity. IM AQ6373-01EN...
Page 24 The power per 1 nm is called the power density. The level axis of the AQ6373 indicates the absolute power per wavelength resolution. For example, if the resolution is set to 0.1 nm, the power per 0.1 nm will be displayed.
Page 25 Thus, the time after a sweep trigger signal is input until the sweep starts will fluctuate in the range of 5 ms.

Page 34: Installing The Instrument
• Do Not Apply Shock to the Instrument non-horizontal orientation, and do not drop the instrument from a height of 2 cm or more. This can adversely affect the accuracy of the internal monochromator and inhibit performance. Take great care when transporting the instrument, and use packaging with a shock absorbing capacity that is greater than or equal to the packaging used upon shipment from the factory. Never use inferior packaging materials that are unable to sufficiently absorb vibrations and shocks occurring during transport. This can adversely affect the accuracy of the internal monochromator and inhibit performance. • When unpacking When the instrument is packaged in a box and moved, prevent condensation by allowing sufficient time for the instrument to acclimatize before removing it from the box. Installation Conditions Install the instrument so that the following conditions are met. Flat Horizontal Location Place the instrument in a stable location that is flat in all directions. If the instrument is used in an unstable or angled surface, the accuracy of the internal monochromator can be compromised. Location without Vibration Do not install the instrument in a location subject to vibration. Use in a location that experiences large vibrations can lead to instability of operation, measurement stopping Index before completion, or notable decreases in accuracy of the wavelength and level axes. Well Ventilated Location Ventilation holes are present at the sides and rear of the instrument. To keep the internal temperature from rising, always maintain a gap of 200 mm or more between the ventilation holes and the installation surfaces. IM AQ6373-01EN...
Page 35 When removing dirt from the case or operation panel, disconnect the power to the circuits under test and the instrument, remove the instrument’s power cord from the power outlet, then wipe gently with a clean, dry cloth. Do not use volatile chemicals since this might cause discoloring and deformation. IM AQ6373-01EN...
