Operating Instructions

Output frequency provided on SMA connector (J17) and J4_IO12.

LEDs indicate the editing mode.

= Edit cursor position mode

= Edit digit value mode

Press and release knob to toggle between frequency editing modes

Edit cursor position mode

In this mode rotating the knob to the left or right will cause the display cursor to move in the corresponding direction on the upper line of the display. Use this mode to position the cursor below the digit you wish to adjust and then press and release the knob to change mode. The cursor automatically skips past the decimal point and space separator and hits ‘end stops’ if you over rotate the knob.

The cursor can be moved into the 10MHz and 100MHz digit positions but these positions are blanked when zero.

The cursor is the small black line under the digit in the top line.

Edit digit value mode

In this mode rotating the knob to the left or right will decrement or increment the value of the digit located at the cursor position. The controller will automatically borrow from, or carry to, the more significant digits to the left of the digit being adjusted. Every adjustment will immediately result in the corresponding frequency change at the output which is also reflected by the changes to the computed DDS control values on the lower line of the display. Press and release the knob to revert to cursor position mode when complete.
