General Purpose Basic Carrier Demodulator
CD15
-
The CD15 Sine Wave Carrier Demodulator operates with variable reluctance transducers to provide a DC output signal for dynamics as well as steady state measurements. A 5kHz sine wave excitation is applied to the two inductance ratio arms of the transducer and the resulting output is demodulated and amplified using the latest integrated circuit techniques. The DC output is obtained from an active filter circuit and gives a uniform response from steady state to 1000 Hz. The low impedance sine wave excitation allows operation with the transducer located over 1,000 feet from the CD15.

Electrical High Speed Digitizer
M8296A
-
The Keysight M8296A is a four-channel, high-speed electrical digitizer module for the AXIe platform. It can synchronously sample up to four incident waveforms and is ideally suited to digitize the output signals from a dual-polarization coherent receiver. Keysight's vector signal analyzer and optical modulation analyzer software serves as the M8296A's user interface and enables a multitude of test and measurement tasks such as spectral analysis and digital demodulation for the analysis of signal quality metrics like error-vector magnitude. Furthermore, the sampled waveform can be stored and processed with the user's own tools (e.g. using Matlab). The modular approach allows users to combine the M8296A high-speed digitizer with other modules in one mainframe such as the M8292A modular optical modulation analyzer and the M8196A 92 GSa/s arbitrary waveform generator.
