I´m using Ad5933 with AFE (AN -1252). the external clock signal is provided by DS1077. I wanna do sweeps from 10 Hz to 1 kHz. I divided my output-signal (excitation) into many pieces to perform sweeps. For example on sweep is from 10 Hz to 30 Hz with an increment size of 1 Hz and id like to perform 20 increments. I programmed a loop with 4 repeats… (Show more)

AD9911 evaluation board has 50 Ohm termination for each single end, total of 100.  And there is a 50:50 Ohm balun afterward.  Isn't it supposed to be a 100:50 Ohm balun?

hello     recently I want to use AD9914 evaluation board to output a linear sweep,i know how to do it through evaluation software.but you have to configure it once it powered down,so now i want to use external way to configure its registers by using STM32.belong are the registers that i configure: const uchar cfr1[]={0x01,0x01,0xc0,0x00}; //cfr1… (Show more)

Hello,I hope to use a AD9914 for linearly sweep, the system clock is 2.5GHz.  The sweep frequency generated is 200MHz -- 300MHz,  and the frequency step is 1MHz, Step intervals is 37.5ns, I  use No-Dwell high configuration, so  it can sweep all the time automatic . Here is my register configuration: CFR1=0x0101C008 CFR2=0x000C2800 CFR3=0x00041927… (Show more)

I am using AD9914 for chirp generation . I started with the 12 MHz bandwidth and 4 usec pulse width at 30 MHz a 1 GHz input. I did the calculation based on the pulse width. The required spectrum I am getting but Freq Vs time graph is showing pulse width in msec. I have attached the register settings as well as the spectrum plot.

I am trying to utilize the trigger out port (J111) on the AD9915 eval board, but it doesn't appear to to ever send any kind of signal.  As far as I can tell, neither the user guide nor the data sheet discusses the trigger or mentions the J111 port, so I haven't been able to figure out if there is something I need to do in order to enable the… (Show more)

Hi, EVAL-AD9954 product requires access to a computer with a parallel printer cable port.what does it look like?how can I buy it? thank you.

I am trying to use the AD9914 EVAL board controlled by a microcontroller instead of the USB. I see how to set the jumpers to set the connections to the USB chip to a high impedance state, but I am confused about the requirements for setting up the registers.   I want to do something fairly simple. I need a programmable output frequency, and… (Show more)

Hi , I want to purchase AD9951 DDS chip to generate multiple signal frequencies in a synchronized manner. In this I want to use FPGA as a controlling mechanism for these DDS chips. What are the parameters I need to consider in selecting FPGA related to AD9951 controlling.
