Technical information:
   - Require Power supply  12VAC or 12VDC
   - 1 Channel
   - 3 Ranges of Frequency by selector switch
                  1: 1-100Hz
                  2: 100-10kHz
                  3: 10kHz-600kHz

NOTE: 20KHz max for TTL output port. Duty cycle cannot be adjust there are 50% - 60% depend on the frequency

   - 3 signal output port
                  1: TTL ( 4.48Vrms )
                  2: Square ( 10.2Vms )
                  3. Sine ( Vmax = 1Vrms )/ Triagle ( Vmax = 1.9Vrms )
   - 2 Pots on board
                  1: Adjust an amplitude of Sine / Triagle  [ Amplitude of square and TTL port can not be adjust ]
                  2: Adjust the frequency
  -  PCB size : 5.2" x 2.42"
  -  Comes with the schematic and part list
