3.2.1.2 Features and Specifications
The oscilloscope combines a lot of features and its interface has many specifications and they are as the following:
Performance
1) High sampling rate: up to 5GSa/s real-time(4GSa/s GDS-350X), 100GSa/ s equivalent time
2) Deep memory: 25K points record …show more content…
The output pressure response from this sensor is 10 pC/psi, which is then converted by an In-Line Charge Converter (Model 422E35) also from PCB Piezotronics. The inline charge amplifier converts the signal with a gain of 0.99 mV/pC. Therefore, the final calibration factor used for converting the transducer signal to pressure is 6.238 mV/psi. Figure 40 shows both the pressure sensor and the charge converter.

The in-cylinder pressure and crank angle position are obtained by AVL QH 33D water cooled piezoelectric pressure transducer and PALAZZOLI digital shaft encoder; the output of the pressure transducer is amplified by an AVL charge amplifier and then the output signals displayed on Instek GDS-3152 Digital Storage Oscilloscope with 150 MHz sampling rate. The accuracy of this pressure transducer is ±13 mV/bar .Figure 41 demonstrates the shape of the used pressure
