Spectrum Marker Generator
NSG-2
National RF, Inc. is pleased to announce the production of a new device, the Type NSG-2 Spectrum Marker Generator. The generator is intended to be used with either spectrum analyzers or communications receivers to mark specific frequency intervals in the RF spectrum. When used with receivers, it is essentially a frequency calibrator, thus making it attractive for use with vintage receivers with analog dials. The NSG-2 provides a leveled amplitude output over nearly 100 MHz of RF spectrum, thus making it ideal to mark frequencies and signal levels on spectrum analyzers. In addition, it may be used with a spectrum analyzer, in lieu of a sweeping type generator, to align lowpass, highpass, and bandpass filters with passbands greater than 20 KHz.

Filter Building Blocks
Analog Devices offers an extensive line of continuous time and clock tunable (switched capacitor) filter building blocks. These devices were designed to simplify the implementation of band-pass, high-pass, low-pass, notch, or all-pass filters using classical filter realizations (such as Butterworth, Cauer, Bessel, and Chebyshev).

Active Filter
J2190A
The J2190A active filter presents a high impedance (approximately 150kOhms) minimizing the loading of the circuit being tested. The output impedance is 50 Ohms allowing low noise coaxial connections to all typical test equipment. The 0.1Hz-10Hz noise band is common for opamp measurements, voltage regulators and voltage references. Many application notes offer schematics of such a filter for test purposes. An engineer’s time is much too valuable to be spent building test equipment. We have created a 4th order high pass and 4th order low pass filter with an optimally flat response and 0dB gain. Additional filters can be cascaded for even sharper cutoff.

High-Power Tunable Filter
CB503
The need for tunable filter technology originates from the fact that high power communication systems and IED Jammer transmitters severely limit the use of tactical radio communication systems on the battlefield.This clash within the radio’s spectrum during tactical missions is often de-conflicted using fixed high Q, high power RF bandpass and bandstop filters installed prior to mission. This can limit operational effectiveness due to the potentially large number of fixed filters required within the allocated radio communication channels, which need be transported, stored in the field, and fitted by trained personnel. Many of these fixed filters centred within the octave wide tuning range could be replaced by a single high-Q tunable filter.
