Main Controller Firmware (U5, ATmega168)
|113-08501-132||[ 2014.08.01 ]
Allow user to restore factory default at power-up. At the firmware version screen pushing ADJ knob will perform factory default restore.

Arbitrary waveform generation (AWG) has been implemented. With support of jyeLab FG085 can now generates any user defined signals.
Implemented trigger input function. Now Output can be controlled by an external TTL signal or a switch. Pressing [ADJ] dial will toggle trigger function on/off. [Photo]
Duty cycle (for square signal only) becomes changeable by user. The change range is 1 – 100% with resolution of 1%. Use [.] (decimal point) button to access the feature.
Improved frequency sweep function. High-to-low sweep can now be done by setting start frequency greater than stop frequency. Bi-directional sweep can be enabled/disabled by pressing [+/-] button. [Photo]

Frequency sweeping feature added. Start frequency, stop frequency, sweep time, and time step size are easily and independently set by digits. Alternatively buttons  –  can be used to access these parameters.
Improved frequency accuracy for signal less than 40Hz in CW mode. Now the maximum frequency error for signal freq. < 40Hz is 0.0005960Hz. Previously this was only true for freq. < 1Hz. Changed powering-up screen. DDS core firmware version is also displayed. Notes:
Firmware version of 113-08502-041 or later must be used for U6 to enable the added features.
|113-08501-110||[ 2012.06.20 ]
In CW mode frequency and time steping size now can be set to any whole number value.
|113-08501-100||[ 2011.06.19 ]
Added features of servo control signal generation.
Added user customizable powering-up screen.
Changed the behaviour of [ESC] key in data entry correction.
