Products – “Spectra-Sense” Swept-Frequency RF/Microwave Sensing Kit
The Spectra-Sense swept-frequency RF/microwave sensing kit is an electro-optic or magneto-optic sensing add-on module. This kit permits extraction of the amplitude and phase of voltage or current-based signals at discrete frequencies that may be swept across your frequency range of interest. The included probe allows measurements within the reactive near field of radiation sources or at the internal nodes of circuits, all with non-intrusiveness and immunity to interference. This kit, which is a subsystem that includes all necessary components and comprehensive instructions for assembly by the customer, is intended for use with either an ultrafast pulsed laser or a stable cw laser (e.g., a DFB laser diode). If such sources are not already available in your laboratory or test facility, a laser can be included with the kit as an option. Overall, these electro-optic and magneto-optic signal-measurement kits will provide cost- effective, easily assembled solutions for extracting amplitude and phase information on a wide range of frequencies for signals that may be found in normally inaccessible locations.
Spectra-Sense Kit Features
- Frequency response from dc to > 100 GHz (pulsed-laser-based kit; up to 40 GHz with cw laser)
- Spatial resolution of measurements < 8 μm
- Free-space or optical-fiber-coupled electro-optic/magneto-optic probes
- Probes allow nonintrusive measurements, do not interfere with other signals, and provide an optically-measured-signal that has immunity from external electromagnetic interference
- Separate amplitude and phase response for individual vector field components
- All optical, opto-mechanical, and opto-electronic parts included
- Detailed assembly instructions with theoretical background and technical guidance
- AFS, our products, and our customer support are backed by an ownership team with more than 40 years of combined electro-optic/magneto-optic sensing experience
Spectra-Sense Kit Applications
- Non-intrusive antenna/array measurements, even in the reactive near-field
- Noninvasive circuit internal-node measurements, including scattering-parameters
- Confirmation of phase coherence in power-combining networks
- Measurements from individual pins of packaged ICs
- Electromagnetic-model validation
- Signal extraction from within cavities and circuit enclosures
- Test/evaluation of EMC/EMI
Spectra-Sense Kit Configuration
You can order the standard experimental kit, which, when assembled will be ready to plug-and-play in an existing
set-up that includes your own ultrafast laser and your own instrument for the signal to be measured, or you
may choose to add any combination of subsystems that are suitable to your needs. In addition to the main optical-
processing subsystem and the options shown below, associated instrumentation, such as a lock-in amplifier,
spectrum analyzer, oscilloscope, or DAQ/control software may be optionally included with the kits.
