Fairfield Circuitry The Accountant

No integrated circuits in the signal path Transformer-balanced input and output Selectable output transformer loading resistors by an internal T4-style electro-optical attenuator Very simple to operate with only two main controls, Gain and Peak Reduction A big meter shows gain reduction or output level at two different reference levels Hardwire bypass switch for easy comparisons XLR and TRS input and output jacks for flexible connections Link jack and switch for conne.
The COMP-3A is a single-channel vintage-style Compressor/Leveler.
The signal path uses only discrete components like resistors, capacitors and transistors, and the input and output is transformer balanced using two different transformers, each one optimized for its purpose.
This is the way audio components were built before integrated circuits became available.
Integrated circuits are small and cheap and widely used in most modern designs.

20:1 OSCILLOSCOPE PASSIVE ATTENUATOR: Can be used with most oscilloscopes to measure injector and primary ignition waveforms. Note that this attenuator should not be used for any high pressure measurements other than injectors and primary igniters.
PASSIVE 20:1 ATTENUATOR: If input 20V signal, it can output 1V signal. Since the signal is attenuated, using this project, the oscilloscope can measure voltages above its range (±20V).
MEASUREMENT RANGE: Due to signal attenuation, using this item, the HT201 attenuator can measure voltages above its range (±20V).
PRODUCT FEATURES: It provides enhanced input overload protection when used in oscilloscopes to measure inductive signals, such as nozzles and primary ignition. Do not use it for secondary ignition tests.
AFTER SALES & SERVICE: If for some reason you are not satisfied with your purchase, damaged, damaged in shipping or even changed your mind. Please feel free to contact us, we will be happy to answer your questions.

A wideband (30MHz-4000MHz), high-performance, general purpose LNA module with a built-in variable attenuator to maximize usability and portability.
The attenuation can be controlled either with the on-board potentiometer (analog control) or push button array (digital control).
Dual amplifier design with adjustable gain (20dB-50dB at 100MHz), low noise figure and low power consumption. Can be powered through bias tee....
