– 19 –PC CONTROLCOMMAND REFERENCE GUIDEDD4 Bandscope Display Information (AI function not linked, withScope mode and Scope range information) Parameters:P1 (Split number)0 ~ 32P2 (Operation mode of Bandscope)0: Center mode1: Fixed mode2: Auto scroll modeP3 (Scope range information 1)In Center mode, the span frequency will notify you.In Fixed or Auto scroll mode, the Lower limit frequency of thescope will notify you.Unit is Hz, blank digits must be entered as “0”.P4 (Scope range information 2)In Center mode, the current center frequency will notify you.In Fixed or Auto scroll mode, the upper limit frequency of thescope will notify you.Unit is Hz, blank digits must be entered as “0”.P5 (Scope display out of range information)0: In range1: Out of range (“Outside of the measuring range” is displayedon the scope screen)P6 (Band scope spectrum display information)20 spectrum information are each expressed as 2 ASCII digits.2 digits of the beginning of division No. 01 are Spectruminformation of the lower limit frequency of the scope range, andtwo digits of the end of division No. 32 are Spectrum informationof the lower upper frequency of the scope range.The range of value for each spectrum information is from 00h ~8Ch (hexadecimal numbering).00h shows the state where the spectrum is extended to thetop (signal strength = 0 dB) and 8Ch shows a state where thespectrum is not displayed (signal strength = -100 dB).The respective spectrum information is converted to ASCII codeof the hexadecimal number of from the upper byte digits. For8Ch, the order becomes “8”, “C”.• When the DD0 command set to “Output to COM / USB(AI function linked)”, it is output from division No. 00 to 32sequentially.• In the Center mode and Auto scroll mode, this command is notoutput when the EXPAND function is ON.• This command operates only at a baud rate of 115200 bps.Answer 11 2 3 4 5 6 7~17 18~28D D 4 P1 P1 P2 P3 P429 30P5 ;Answer 21 2 3 4 5 6~45 46D D 4 P1 P1 P6 ;DF ⊿F Display Parameters:P1 (State)0: Simplex mode1: During split mode or split frequency operationP2 (Code)0: Plus1: Minus When P1 is 0, P2 also becomes 0.P311 digit frequency in Hz Enter unused digits as “0”.
