20:1衰減器(PP198)

PP198衰減器能夠讓示波器測量噴油嘴和初級點火波形。

PP198衰減器是一個無源的20:1衰減器。這說明輸入一個20V的信號,就輸出1V的信號。因為信號被衰減,PP198衰減器可以讓示波器測量電壓高于其輸入范圍±20V。

當把PP198衰減器用于示波器測量感應信號例如噴油嘴和初級點火時,它提供增強的輸入過載保護。千萬不要把它用于次級點火測試。

The PP198 has been designed to allow fuel injector and primary ignition waveforms to be measured using PicoScope oscilloscope products. Please note this attenuator should not be used for any high voltage measurements other than fuel injectors and primary ignition.

The PP198 is a passive 20:1 attenuator. This means that a 20 V signal at its input will appear as a 1 V signal on the output. As the signal is attenuated, the PP198 allows voltages of up to 300 V to be measured (see the safety precautions).

The PP198, when used with Pico PC Oscilloscopes provides increased input protection against overloads when working with inductive signals such as injectors and primary ignition. Under no circumstances attempt to use this attenuator to measure secondary ignition (HT) waveforms, the PP178 Secondary Ignition Pickup lead should be used for this purpose.

 

How to Use the 20:1 Attenuatorattenuator

The PP198 connects in series between the oscilloscope and the test lead (right photograph). The PP198 is only suitable for use with an input channel — it is not suitable for use with an external trigger input.

PicoScope can be configured to work with a 20:1 attenuator probe by selecting first the Settings menu and the the Probes menu. Select 20:1 attenuation for the channel the PP198 is plugged into.

Specifications
Attenuation 20:1
Input Impedance 1.053 MΩ
Input capacitance 11 pF
Bandwidth 10 MHz (-3 dB)
Max input 300 V

 

Safety Precautions

The PP198 is designed for measuring automotive signals such as fuel injector and primary ignition voltages (nominally 6, 12 or 24 volts). This attenuator must not be used to measure mains voltages 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.
