Signal Attenuators, different ranges, for multiple oscilloscope models

SKU: AT Category:

Description

Product under develop. It will be available around end February 2023.

By using this item, the oscilloscope can measure the voltage higher than its range. For example an input signal of 20V can output 1V signal or a standard oscilloscope with ±5V input range can become ±20V input range. Mainly for automotive use, i.e. fuel injectors and main point arc waveform.

It’s unique feature is the possibility of compensation that allow to be used with several oscilloscope brand and models.

Requirements

  • Oscilloscope with input impedance 1MOhm, BNC connector.
  • Regulation of compensation requires a square waveform between 1 and 10KHz.

Package Includes

  • x1 piece attenuator
  • x1 plastic screwdriver for the regulation of the compensation

Note

Do not use this attenuator for high voltage measurement except fuel injectors or primary ignition. This attenuator must not be used to measure mains voltages, secondary ignition or other hazardous voltages.

Fuel injector and primary ignition signals contain short duration high voltage spikes “inductive kicks”. We therefore recommend the use of two ground connections between the oscilloscope and the vehicle under test. One ground connection is made using the measurement test lead. A second ground lead should be connected between one of the BNC connectors on the oscilloscope and a secure ground point on the vehicle such as the negative terminal of the battery. Misconfiguration and/or failure to follow these warnings may cause damage to the product and/or computer and could cause injury to yourself or others.
