Dual-USB3 Polarization Cameras
Celera P Series
-
Standard digital monochrome sensors capture light intensity and wavelength for each pixel: however, some applications require the inspection of polarized light to get relevant information.Instead of using external polarizing filters, Alkeria developed CELERA P, a new camera model featuring a special polarization image sensor.Thanks to its unique array of polarizer filters overlaid on top of the sensor's pixel array, CELERA P gets rid of all the external polarizing filters, combining the ease-of-use of the Alkeria USB3 cameras with the advanced capabilities of polarization imaging and unique FusionView feature.

Analog Power Supply
Type NPS-2412
-
National RF's Type NPS-2412 analog power supply was designed to be used in communication equipment where radiated switching inverter noise from conventional “switching type” supplies is not acceptable. The power supply consists of a standard rectified transformer output driving a pair of voltage regulators and filtering networks. The 2412 offers an adjustable voltage output between 2 and 24 volts as well as a fixed voltage output of 12 volts. A maximum of 20 Watts of DC power can be supplied from the unit. As the voltage regulators dissipate power in the regulation process, the power to the load is derated accordingly, dependent on the set voltage to the load. The adjustable regulator is a standard LM-317T integrated circuit device. The fixed regulator is a standard LM 7812 device. Upon customer request, the LM 7812 device may be changed to any voltage rating within the the LM-78xx series of regulators. Contact National RF for this modification if desired.

Mini Receiver
FB7-NX
-
In about 1935, the National Radio Company of Malden, Mass., brought out a “hot” high frequency receiver, called the FB7, and the subsequent FB-7X. It featured a super-hetrodyne design with plug-in coils that gave it a broad frequency range. The “X” model also incorporated a crystal filter in the intermediate frequency section, thus giving it additional selectivity. The receiver was viewed by radio amateurs as a technological breakthrough, and it was also used commercially for point to point high frequency communications. As the receiver did not have an internal RF amplifier section, a separately tunable RF amplifier was later provided in a separate enclosure for additional performance capabilities. Now, National RF, Inc., is resurrecting the fabled receiver name with an all solid-state, hot mini receiver, which also utilizes plug-in coils to cover the HF spectrum. The mini-receiver is designed for use by radio amateurs as well as serious short-wave listeners, and allows reception of AM, CW, and SSB signals. It incorporates a super-hetrodyne design with a dual gate FET built-in RF preamplifier and a ceramic filter for selectivity, often required when used in a crowded amateur radio band. In addition, the receiver has a buffered rear panel output of the high frequency oscillator for use with either a frequency counter for exact receive frequency display, or for interface with an outboard transmitter. A rear panel jack is also provided for muting the receiver when a transmitter is placed into the transmit mode. And, the receiver is small enough to fit into carry-on luggage and taken on trips when it is desired to “keep an ear” on amateur radio or other high frequency activity. The receiver utilizes rear panel plug-in coil assemblies which contain the RF amplifier, mixer, and oscillator tuned circuits. Each plug-in coil assembly also comes with a separate dial scale, which is inserted onto the front panel for displaying the tuned frequency. A very smooth 6 to 1 planetary drive is used for tuning the receiver. Other front panel controls include RF preamplifier peak, volume control, Beat Frequency Oscillator adjustment, and RF gain control. Other switches include filter bandwidth, AM/CW/SSB selection, Power, and a general coverage/band spread control for certain plug-in assemblies. The receiver is intended to drive head-phones via a rear panel jack, but has sufficient output to drive a small external speaker.

Test Data Organization
-
Filters enable you to organize your data in a dynamic rather than a static way. Using filters, you can organize your issues, tests, testSets, and requirements, based on their fields, and have the information, displayed in multiple ways. For example, you can create 2 filters in the Test library module - one that displays the tests that are related to the DB server and the other filter displaying tests whose priority is ‘Show Stopper’. A test that has its component field set on ‘DB server’ and its Priority set on ‘Show stopper’ will appear in both trees accordingly.

Frequency Synthesiser
RA062-F2
-
The RA062-F2 is a multiple LO module used to generate three pairs of LO signals, each pair being phase matched in order to provide the capability to drive two phase and amplitude matched, high sensitivity narrowband receivers such as might be required for an EW receiver system with DF functionality.The Stepped Frequency Synthesiser is based upon Direct Frequency Synthesis, DFS, whereby the 1GHz input reference signal is multiplied, filtered and mixed to generate a given number of isolated and filtered single tone CW signals from the 1GHz comb. A finely tuned signal is then generated using a multi-way switch to select between the 1GHz spaced CW tones and mixed with fine resolution signals generated using a custom DDS/VCO PLL network. In this way finely tuned signals can be generated between 7.5GHz and 23GHz.
