ERAVANT
Wide mechanical tuning bandwidth Gunn oscillators utilize high performance GaAs Gunn diodes and various cavity designs to yield near full band frequency coverage. Unlike dual-tuner oscillators, frequency and power optimization are accomplished by a single micrometer. Furthermore, these oscillators can be modified into electrically tunable oscillators by replacing the micrometer with an electrical actuator. The wide tuning bandwidth of these oscillators offers a low cost, high performance means of signal generation, making them ideal test sources for labs and antenna ranges. While standard models offer a waveguide interface, a coaxial interface is also available. When used with a Gunn oscillator regulator/modulator (SOR series), these oscillators can produce AM or FM modulated signals for many test applications.

2.7 GHz, 50 Ω, Dual-Terminated SPDT PXI RF Relay Module - The PXI‑2549 is a general-purpose single‑pole double‑throw (SPDT) switch module. You can use it to add flexibility to your switch network or to maintain uniform signal paths across multiple channels when building high‑channel‑count multiplexers. The PXI‑2549 termination resistors minimize reflections on open channels and protect your source or device under test from damage. The module also features excellent insertion loss, voltage standing wave ratio (VSWR), and isolation parameters to minimize signal degradation. You can use its onboard relay count tracking feature to predict relay lifetime and reduce unexpected system downtime.

Notice
LD Driver slot module of FOTS system is an efficient module that is user centered, which can drive various kinds of laser diode for the use of optical signal transmission or light source. The module has a built in LD socket, in which LD of 14 pin butterfly type is installed, which makes it possible for the user to change the LD he or she wants to drive when needed. It is leaded to get rid of the inefficiency of expense, at which various types of expensive united source module needed are purchased. By operating monitoring PD and high-performance processor that are installed inside the module, the output power and temperature of LD can be driven accurately and stably. The laser diodes can be modulated internally in square, sinusoidal, and triangular waves and its output power and temperature can also be maintained the level set by the user. In order to realize the various functions, the efficient and multi-functioned control programs with high speed processor, LCD monitor or GUI for remote control are available.
