Functions:
Automatic Polarisation Adjustment
The Advantest Q7607 has an automatic polarisation adjustment that facilitates fully automated high-speed and high-accuracy measurements.
Built-in Optical Amplifier (Q7607) Option 10
The Advantest Q7607 comes with a built-in optical amplifier that conditions the output signal for unamplified high-bandwidth O/E converters. This Option automatically controls the amplifier gain, which improves both measurement accuracy and S/N ratio measurements.
Features:
Quick Time-Domain Chirp Measurements: 30 seconds or less
Until now, no simple and easy to use method existed to measure dynamic optical chirp. With the Q7607, ADVANTEST makes dynamic chirp measurements a simple and easy process by automatically separating the frequency-modulation (FM) and intensity-modulation (IM) components with a Mach-Zender Interferometer (Conventional methods using spectral diffraction take 20 minutes or more for chirp measurement). Q7607 allows the user to measure dynamic chirp in 30 seconds or less.
High-Resolution
The Advantest Q7607 provides chirp data with approximately 20 MHz resolution or better.
Wide-Measurement FSR
The Advantest Q7607 provides a FSR (free spectral range) of 300 GHz. This allows the Q7607 to measure transmission signals up to 50 Gbit./s
Simple Operation
The user can measure and display chirp using almost any personal computer. Advantest provides an operation software free of charge which allows a comfortable chirp measurement on the PC.
