DC8V-9V AD9850 6 Bands 0-55MHz Frequency LCD DDS Signal Generator Digital Function Module Signal Generator

Features 1 Supports 0 55MHz continual adjust at 1Hz step 2 This generator has 78L05 voltage regulate Input current at 200MA input voltage 8 9V would be the ideal voltage 3 Input voltage of 12V can only be used for short time testing otherwise will cause heat to board 4 5p 6p connect to the encoder as per photo 7p of the middle connects to digital matrix input 14p 8V GND is 8V power supply from main board 5 If powered by mainboard DDS does not need an independent power supply 6 1 6 correspond to 6 frequency bands 3 8 7 9 14 18 or 21 27 or 29 7 ISB USB CW are the three mode choices 8 DT is signal from mainboard Keys and Connection interfaces ENC Encoder switchMEM Switch for memory modeVFO Transfer from VFO A to VFO B or from VFO B to VFO A SSB Working mode change circulate from USB LSB AM CW and on and on RIT Fine tuning to receiving frequencyCAL Set functionsKB 1 and KB 2 have a common shared pin but is not GND Specifications Display 1602 LCDInput voltage DC 8V 9VInput current 200mAFrequency range 0 55MHz6 bands 3 8 7 9 14 18 or 21 27 or 29Product size approx 80 45 30mm 3 15 1 77 1 2inchNet weight approx 66g 2 32ozGross weight approx 69g 2 44oz How to operate Press CAL power on then we enter the setting screen Let go release CAL A ENABLE 6XREFCLE setting chip clock mode adjust frequency encoding setting AD9851 set to a 6 multiply frequency AD9850 set to 1multiply frequency Press CAL then quickly
