Description

The traditional Plasma Impedance Probe (PIP) is popular for diagnosing parameters of the ionospheric plasma to study the space environment. However, the resolution of data measurements of existing PIP instruments, operating at higher frequencies, limits the analysis to studying the plasma features at electron scales. Studying plasma ion parameters is essential to understanding the ionospheric instability growth rates. This can only be accomplished by operating a diagnosing instrument at lower frequencies corresponding to ion scales. A recently developed Time Domain Impedance Probe (TDIP) is implementable for fast moving spacecraft using a time domain approach. The instrument has higher measurement resolution and can be operated for investigating both the lower ion and higher electron frequencies. In this research, we will study the response of TDIP circuit board using TINA-TI software simulation data obtained at higher frequencies in order to accomplish the necessary calibration needed for the device. In addition, the research will present a concept to modify the design of TDIP to study plasma dynamics at the lower ion scale frequencies. In this research, we simulate the TDIP circuit in TINA-TI software to observe the response at output end before ADC. Here, the input pulse is considered as the output of DAC in original TDIP schematic diagram.
