RF Band(MHz) & Solar Attn(dB)- RF1 : 306 MHz ,RF2 : 306 MHz, SA1 : 0 dB, SA2 : 0 dB 12. Ist LO (MHz) & IVth LO (MHz): ILO1 : 255 MHz, ILO2 : 255 MHz , IVLO1 : 51 MHz, IVLO2 : 51 MHz 13. IF Attn(dB) , IF BW(MHz) & IF ALC : IF-CH1 : 4+12 dB, 32 MHz,ON, IF-CH2 : 4+12 dB, 32 MHz,ON GSB SETTINGS : 14. GSB Mode : RealTime 15. GSB LTA : 8 16. GAIN EQ : ON 17. Stokes : Total_Intensity 18. Beam - 1 : OFF 19. Beam - 2 : OFF 20. ACQ BW : 32 MHz 21. Maximum Channels : 256 22. IFBW (MHz) : LO5 (KHz) : 32:149000-156000 23. Final Bandwidth (MHz): OFF MHz; Step # 0 24. Frequency Parameters (TPA) : 306 306 255 255 51 51. 25. Integration Time : 16.106 Sec. 26. No of Antennas Working(Fringing) :28 27. Name of Non-Working Antennas (with reason for each) : E03 : BLDC work. E04 : Servo Work. 28. Note for Backup :-- 29. Start and End Time of Obs.(IST): 19:00 - 05:30 30. ONLINE Machine : Shivneri 31. Comments (During Observations) : 18:40 : Started set up for 325MHz. 19:00 : Antennas (C00,C01,C02,C03) vanishes fringe for 175 pole as started scan and hence GSB take more time to start. 19:40 : GSB problem is solved and started scan on 3C286. 19:50 : Stopped scan on 3C286. 19:57 : Started following command file.
