Burst-Generator
SFT 1420
The test generator SFT 1420 simulates quick transient noise interference as they are defined in the standard IEC / EN 61000-4-4. The single pulses show a very short rise-time (5 ns) and due to this a wide RF-spectrum up to 300 MHz. RF interferences are the result.

ICE 3000 Series
ICE3009
The ICE3009 subsystem is an agile filter for the VHF-L, VHF-H and UHF frequency bands. It allows operation of a number of transceivers in a cosite environment. The VHF/UHF Filter provides multiple poles of RF selectivity to reduce broadband noise in transmit mode of operation and to reduce interfering signals at the transceiver’s RF input in receive mode at Have Quick II/IIa and SATURN tuning speeds. This design incorporates a flexible control scheme that can be configured at the factory for various radio interfaces (ARC-210, ARC-231, ARINC 429, etc.). The design is highly integrated and includes all filters, amplifiers, power supply, transmit and receive switching (including a bypass mode), and Built-in-Test (BIT). A mounting tray is available as an option for easy incorporation on your platform. This system is qualified for military applications. Cost-effective modifications are available on the ICE3009. Please contact your sales representative at 513.870.9060 or Support@PoleZero.com for details.

Fourier Transform Optical Spectrum Analyzer, 600 - 1700 nm
OSA202C
Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.
