External Pre-amplifiers
-
Although all Spectrum A/D cards have a very powerful input section with a highly configurable input amplifier and a variety of input ranges it is sometimes necessary to have additional external amplifiers if the signal to acquire has an extremely low level. Spectrum offers a range of perfectly matching external amplifiers to cover such cases. These powerful amplifiers have been rated using the Spectrum cards and offer best performance together with high amplification rates.The amplifiers are simply connected between the signal source and the Spectrum A/D card input and can be manually switched between different settings using small lever keys. All amplifiers allow the offset compensation by using an adjustable screw.

Low Noise Pre-Amplifiers
-
Low Noise Pre-Amplifier and companion external low noise amplifier (LNA) are used to amplify low level microwave signals. The Pre-Amplifier contains an AC/DC power supply, internal low noise amplifier, and a bias tee to source a DC bias voltage on the RF input connector.To overcome cable loss between the test antenna and the Pre-Amplifier assembly, a remote low noise amplifier (LNA) is mounted directly onto the 10 GHz antenna. A bias tee inside the Pre-Amplifier chassis powers the remote LNA through the coax cable interconnecting the pre-amplifier and the 10 GHz test antenna.

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.

G.R.A.S. Sound & Vibration A/S
It provides polarization voltage for the transducer, ensuring that the microphone gets the charging voltage it needs.It provides supply voltage for the microphone preamplifier. The preamplifier acts as a unity gain impedance converter. It provides a certain amount of line drive capability by providing a low output impedance and output current, making it possible to transmit the signal from the transducer to the Power Module without significant degradation.A power module can provide amplification or attenuation to the signal, thus making it possible to fine tune the measurement chain to the signals being measured and the hardware being used.Selectable filters make it possible to exclude unwanted noise from the measurement, e.g. wind induced noise from outdoor measurements.Overload detection makes it possible to validate the measurements and is a useful tool in monitoring setups.When a Power Module with gain is used, you can use longer cables because of the power module's ability to deliver current.A Power module introduces electrical isolation
