Each data point consists of 512 electric field intensity in a frequency range from 20 kHz to 5.12 MHz with a band width of 1 kHz. The frequency variation in each data block is given with linear function of corresponding step number; i.e.\n- data block 1 (step 1 - 64) : 20kHz - 140 kHz\n- data block 2 (step 65 - 128) : 140kHz - 380 kHz\n- data block 3 (step 129 - 192) : 380kHz - 1340 kHz\n- data block 4 (step 193 - 256) : 1340kHz - 5120 kHz\n\n## Data Analysis\nHere, you can find [a TDAS load procedure file for PWS electric field intensity spectrum data](https:\u002F\u002Flegacy.darts.isas.jaxa.jp\u002Fapp\u002Fstp\u002Fakebono\u002Fakb_load_pws.pro). PWS electric field intensity spectrum data analysis becomes available on TDAS with this load procedure. TDAS (THEMIS Data Analysis Software suite) has been developed by THEMIS project.
