Solid State Voltage Injector
J2110A
-
While it is possible to obtain high quality injection transformers with bandwidths as wide as 1Hz to 5MHz or more, in some cases this is still insufficient for some tests. For example a typical heater control loop might have a bandwidth of less than 1Hz while some linear regulators and opamp circuits can have bandwidths of up to 100MHz or in some cases even higher. For these applications, a solid state injector can provide the necessary bandwidth. A solid state injector can perform at DC, while the upper frequency limit is dictated by the components selected and the printed circuit board material and layout. It is possible to obtain a solid state injector with a working range of DC – 200MHz, though above 50MHz the interconnection between the injector and the circuit being tested can become quite critical. It is essential that ripple from the injector power supply does not dramatically degrade the dynamic range or the signal to noise ratio of the measurement. The resulting plots are often much cleaner when using a solid state injector than with a transformer injector.

Power Supply
-
The Power Supply Systems are the heart of any experiment. They provide the High voltage and Low voltage required by the detectors and by the related front-end electronics. The quality of the power supply is critical to obtain the best performance from the set-up. The sensibility of modern detectors, in fact, make them susceptible to any even small variation in the power supply, and so features like low Noise, low Ripple and high stability become essential in the design of a performing power supply system. Strong of 40 years of collaboration with the most important research labs worldwide CAEN offers today sophisticated High Voltage Power Supply and Low Voltage Power Supply Systems. The demonstration of this successful long-standing tradition is the “CMS Crystal Award 2009” that CAEN received for the development and production of the power system for the CMS tracker. CAEN offers a wide selection of Power Supplies in different form factors and standards:- For smaller set-ups Standalone or modular (NIM / VME) products or are the ideal fit.- For bigger set-ups, where a high number of High voltages and Low voltages is required, the Mainframe Systems and Boards (up to 48 channels/board, up to 768 channels in a single Mainframe) are the most recommended.

20 GHz Signal Source
VCO Series
-
The SC5510A and SC5511A are VCO-based, synthesized signal sources with very low phase noise and an amplitude control of 0.01 dB throughout its -30 dBm to +15 dBm output power range. By utilizing a unique multiple phase-locked loop architecture, phase spurs are kept below -70 dBc across the entire tuning range, even at 1 Hz step resolution. Download the data sheet to see how the impressive features and specifications of these modules make them stand out when compared to other small modular synthesizers. These 20 GHz signal sources include an additional, independent RF2 channel with a tunable frequency range from 100 MHz to 3 GHz and a tuning resolution of 25 MHz. The extra channel makes the modules suitable for either single-stage RF conversion systems or dual-stage image suppression up/down converter systems. Both modules make great general-purpose laboratory signal sources where demanding low phase noise and signal purity are required. They are both ideal choices as an integrated clock source for fast DAC and ADC applications, especially those that require variable sampling rates. Full implementation instructions, GUI, driver software, and example code are provided with each module.

RF Test Spectrum Measurements over CPRI
Integris 3000
-
Most modern cell tower network configurations place the Remote Radio Head (RRH) at the top of the tower and the baseband unit(BBU) at the bottom of the tower. While this configuration is advantageous for both computational efficiency and mitigation of RF loss across the cable, it means the only place along RF can be accessed is at the top of the tower. This forces field technicians to have to climb the tower to measure and debug RF noise problems.

VECTOR-GUN HANDHELD DIRECTION FINDING ANTENNA SYSTEM
HFDF
-
National RF's Type HFDF active directional antenna system consists of a high gain RF amplifier coupled to a tunable Faraday shielded loop antenna. Several loop antenna assemblies are available to provide coverage of frequencies in the HF and low VHF spectrum. Due to the nature of a Faraday shielded loop, the antenna exhibits a sharp null through the diametric center of the loop. This null is used to determine the direction of incoming radio signals or to locate electrical noise being radiated from some source. The internal high gain amplifier is used to compensate for the inherent inefficiency of the actual loop at the operating frequency. Overall, the system dynamic response is about +6 dB as compared to the dynamic response of a dipole. To aid in the direction finding process on strong signals, an internal 30 DB attenuator is provided. As the loop antenna presents a bi-directional response, tri-angulation may be required to eliminate the ambiguous signal direction. The line of site of the incoming signal is determined by listening for a signal null on the receiver or by watching the receiver’s S-meter.
