The Advantest TQ8210 handheld Optical Power Meter uses either a silicon photodiode sensor (for short wavelengths) or an InGaAs or a germanium photodiode sensor (for long wavelengths). A compact sensor facilitates measurements in clamped places. It is suitable for use in R&D applications for optical telecommunications, laser printers, CD equipment and magneto-optical disks. The TQ8210, in its compact body mounts full application of Advantest’s measuring technology and features a wavelength sensitivity compensation function, eliminating measurement errors which usually occurs when the range is changed or a new sensor is connected. The TQ8210 features a two-way power supply (including a chargeable Ni-Cd battery), allowing you to use it anytime and anywhere. Mainframe Specifications. Resolution: 0.005 to 0.1% (with unit of W), 0.01 dB (with unit of dBm). Absolute Accuracy of A/D converter: ±0.2% (included sensor measurement accuracy). Display: LCD with back light for use in dark location, Wavelength readout 4 digits(nm), Power readout 4-1/2 digits (mW,µW, nW, dBm, dBr). Range switching: Automatic or manual. Measurement speed: 2 Measurements/s or faster. Max-hold (for wait measurement): The maximum measured value is held. dBr (for dBr measurement): The value relative to a reference value is indicated. Wavelength sensitivity compensation: Automatic compensation of sensor sensitivity at set wavelengths. Smoothing function: Digital smoothing (by moving averages, 2 to 20 averages). Offset and zero: Stores sensor offset for automatic compensation. Analog output: Proportional to the input signal. Output voltage: 0V to 2V Output impedance: Max 10 ohm. Output connector: 2-pin mini-jack. Optical Sensors Specifications (Option); Q82014A, Wavelength range 0.4 to 1.1 µm. Q82015, Wavelength range 0.8 to 1.6 µm. Q82017A, Wavelength range 0.4 to 1.1 µm.
