SKU: EB0045952
Favorites
Key Features
This is a 0~55MHz DDS Signal Generator. It is based on AD9850 chip and is very easy to operate.
Supports 0~55MHz continual adjust at 1Hz step.
Input 12V (Seller's Note: We are also providing a simplified version, with input 8~9V)
With direct digital input frequency
With audio volume potentiometer
With amp. gain potentiometer
With AGC potentiometer
S-LED display
Standing Wave-LED display
Keys & Connection interfaces:
ENC: Encoder switch
MEM: Switch for memory mode
VFO: 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 frequency
CAL: Set functions
KB-1 and KB-2 have common shared pin, but is not GND.
Notes:
DDS SYSTEM CLK: can use frequency tester to get 30MHz oscillator, multiply the tested value at 6, then put the multiplied value here. If using AD9851, make initial setting at 180000000.
OFFSET FREQ: can be set as + or - . Rotate encoder switch to change value, press STEP key, then rotate encoder switch to adjust step. Minimum working frequency plus (+) offset frequency should be high than 0 (zero).
Frequency display:
RX = MULTIPLIER x (RX_DDS_FREQ + OFFSET_FREQ)
TX = MULTIPLIER x (RX_DDS_FREQ + OFFSET_FREQ + TX_OFFSET_FREQ)
The frequency programmed into the DDS, is calculated as shown below.
RX = ABS(RX_DDS_FREQ)
TX = ABS(RX_DDS_FREQ + TX_OFFSET_FREQ)
RX_DDS_FREQ, MIN_RX_DDS_FREQ, MAX_RX_DDS_FREQ, TX_OFFSET_FREQ & OFFSET_FREQ
Examples:
1. DDS output range 30~40MHz:
MIN_RX_DDS_FREQ MAX_RX_DDS_FREQ OFFSET_FREQ RX Frequency display range.
30 MHZ 40 MHz 100 MHz = 130 MHz to 140 MHz. Note 1
30 MHZ 40 MHz -10 MHz = 20 MHz to 30 MHz. /
-40 MHZ -30 MHz 170 MHz = 140 MHz to 130 MHz. Note 2
-40 MHZ -30 MHz 60 MHz = 30 MHz to 20 MHz. /
2. Setting FT180A with DDS:
ENABLE RPT NO
X6 RECLK X6
DDS SYSTEM CLK 180M
MAX DDS FREQ 65M
MIN RX DDS FREQ 10.701M (Offset frequency + RIT frequency)
MAX RX DDS FREQ 60M
TX OFFSET FREQ 0
MAX RIT OFFSET 1K (RIT frequency)
OFFSET FREQ - 10.700M - (Offset frequency)
