<h4>2.2: NCO frequency shift</h4>
This is the frequency shift applied when the NCO is engaged thus the actual LO frequency is the center frequency of reception minus this value. Use the thumbwheels to adjust frequency as done with the LO (1.1). Pressing shift simultanoeusly moves digit by 5 and pressing control moves it by 2. The boundaries are dynamically calculated from the LO center frequency, sample rate and hardware decimation factor.

The boundaries are dynamically calculated from the LO center frequency, sample rate and hardware decimation factor.
&#9758; In the LMS7002M TSP block the NCO sits before the decimator (see Fig.14 of the [datasheet](http://www.limemicro.com/wp-content/uploads/2015/09/LMS7002M-Data-Sheet-v2.8.0.pdf) p.7) so it runs at the actual ADC rate. Hence the NCO limits are calculated as +/- half the device to host sample rate multiplied by the hardware decimation factor. For example with a 4 MS/s device to host sample rate (5) and a hadrware decimation of 16 (3) you have +/- 32 MHz span around the LO for the NCO. In this example you can tune all HF frequencies with the center frequency set at its lowest (30 MHz).

You can set the translating frequency in Hz with this dial. Use the wheels to adjust the sample rate. Left click on a digit sets the cursor position at this digit. Right click on a digit sets all digits on the right to zero. This effectively floors value at the digit position. Wheels are moved with the mousewheel while pointing at the wheel or by selecting the wheel with the left mouse click and using the keyboard arroews.

This global gain is set with button 9.2. When manual gain is engaged the LNA, TIA and PGA gains can be set independently with the 9.3, 9.4 and 9.5 buttons respectively.
