Process RF Analyzer
IMPS-4400
The Sensortech Instant Moisture Profiling System (IMPS-4400) is a non-contact RF moisture profiling system for board manufacturers to improve and optimize production processes and meet quality standards, reduce energy costs, increase productivity, and generate revenue. The IMPS-4400 utilizes radio frequency antennas to analyze board moisture characteristics below the surface, which is critical information to ensure consistent quality of finished boards.

RF Proximity Detector
Type RPD-2 AND Type RPD-2A
The Type RPD-2 Radio Frequency (RF) Proximity Detector is designed to detect and locate devices that radiate radio waves in the high frequency to low microwave frequency range. Such devices often include surveillance and “spy” equipment. The Type RPD-2, when used with the different sensors, will detect the emanation of the radio wave within a confined area, and then isolate its location to within approximately a square foot. The type RPD-2A may be used as an RF field strength indicator for antenna field strength measurements. The RPD-2A is identical in function except that the meter scale is calibrated in relative dB units.

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 ...show more -

Receiver Semi-Kit
75-NS-3
National RF’s 75-NS-3 receiver is a complete super-hetrodyne mini high frequency receiver, designed specifically for the short-wave listener, electronics enthusiast or radio amateur, who wants to use their hands and build a radio. The receiver is offered as a semi-kit in which the electronic assembly is loaded and functionally tested at the National RF facility. The customer must then go to the grocery store (yes…the grocery store!), procure a can of lunch meat, eat it or give it to the dog, an...show more -

Vector Finders with InternalAttenuators
VF-145 LA AND VF-145 LMA
The VF-145 LA and LMA models are functionally the same as the VF-145 L and LM on both electrical performance and mechanical specifications. However, the LA and LMA models include an internal PIN diode attenuator that provides up to 12 dB of attenuation (measured at 150 MHz, attenuation decrease slightly as operating frequency increases) to the incoming radio signal. This attenuation occurs after the signal is received by the unit and phase shifted for processing, but before it is placed on the ...show more -

FREQUENCY DISPLAY UNIT
TYPE NFD-1
The National RF Type NFD-1 Frequency Display Unit was designed for use with vintage and classic communications equipment, to display the received or transmitted radio frequency. The unit incorporates an internal processor that allows the intermediate frequency (IF) to be counted out by the frequency counter. The resultant display is the actual frequency that the equipment is receiving or operating at.

Frequency Down Converters
In digital signal processing, a digital down-converter (DDC) converts a digitized, band-limited signal to a lower frequency signal at a lower sampling rate in order to simplify the subsequent radio stages.

Array Antennas
An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. The individual antennas (called elements) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship. The radio waves radiated by each individual antenna combine and superpose, adding together (interfering constructively) to enhance the power radiated in desired dir...show more -

Radio / Conformity Tests
The safe and effective use of radio frequencies (HF), referred to in English as radio frequencies (RF), must be checked for every device with integrated radio technology. The legal requirements for radio frequency (HF) tests vary depending on the use of the device (medical devices, automotive and telematics devices, cellular devices, etc.).
