The output frequency is 100 MHz. DDS9910 Phase Noise, PLL Enabled (50×20), Output: 100 MHz Figure below shows the phase noise level when using an external reference clock frequency of 1 GHz (RCLN1000), with the PLL OFF.The output frequency of the DDS is 100 MHz. DDS9910 External Clocking – 1GHz, Output: 100 MHz, Level: +4 dBm Let’s compare these two graphs, for example, at a 10 kHz offset from the carrier: with the internal PLL system engaged,the phase noise level is -129 dBc/Hz, while with the PLL system disengaged and using external clocking, the phase noise is -140 dBc/Hz.This means that using an external clock signal results in a phase noise that is 11 dBc/Hz better (lower).For the same output frequency, but at a 1 MHz offset from the carrier, with the internal PLL system engaged,the phase noise level is -124 dBc/Hz, while with the PLL system disengaged and using external clocking, the phase noise is -152 dBc/Hz.This means that using external clocking results in phase noise that is 23 dBc/Hz better (lower).Conclusion:When using external clock, you can get much lower phase noise than using the built-in PLL.But do not forget that in order to achieve such results, increased requirements are put forward to the external oscillator.For maximum performance we recommend our Ultra-low noise reference oscillator 1GHz RCLN1000. We recommend to use Ultra Low Noise Reference Oscillator with our DDS Shield Boards:RCLN1000 1GHz Ultra Low Noise Reference Oscillator https://www.ebay.com/itm/256107727808 If you need higher power output: The first and simplest method to increase the power from the nominal 0 dBm to +4 dBm is by activating the “Hi-Current” option in the menu (refer to Operation instruction).NOTE: enabling this setting leads to increase in harmonic levels of the output signal. If this level of power is still insufficient, there is a second method – connecting an external RF signal Amplifier, such as the MMIC MRFA89.It allows obtaining a DDS signal output power of up to +20 dBm.IMPORTANT: Since the MMIC MRFA89 Amplifier has maximum output power of +20 dBm and gain of 20 dB, the recommended maximum input signal level is 0 dBm.Therefore, the ‘Hi-Current’ parameter should be deactivated in the AD9910 Shield menu.NOTE: as most amplifiers generate harmonics, it is advised to connect an LPF Filter to the Amplifier output for harmonic suppression.For example, one from the LPF 7th Order Elliptical series that we offer. We recommend to use RF Amplifier and Low Pass Filter with our DDS Shield Boards:RF Amplifier LNA 8-2000 MHz, GAIN = 20 dB, P = +20 dBm + LDO MMIC MRFA89 SOT-89 https://www.ebay.com/itm/254839685974 (Low-Pass Filter LPF 7th Order Elliptical 1-1000Mhz 3.5 7 14 28 144 433MHz etc.) https://www.ebay.com/itm/255124015393 OLED Display Menus: Remote control of DDS Generator through USB connection from PC using the terminal serial port: List of Serial Port Commands:Starting with version 1.02, the ability to control via the serial port has been added.F – Set Frequency in Hz (100000 – 600000000)P – Set Output Power in dBm (-72 — 0 OR -68 — +4, depending on “DAC current”)E – Enable OutputD – Disable OutputM – Get ModelV – Get Firmware Versionh – Help; – Commands SeparatorExample:F100000;P-2Set Frequency to 100 kHz, and Output Power to -2 dBm.Any number of commands in any order is allowed.
