Hi Noel,

Thank you for your response.

I’m completely new to this product and planning to purchase the evaluation board. Could you please let me know if it’s possible to view the output waveform using a DSO? Or is a spectrum analyzer absolutely necessary?

Regards,

Athira K

Hi There,

Yes, we can measure the output signal with a scope as long as the bandwidth of the scope is higher than the signal frequency.

However, if you want to measure spurs, phase noise, you need to use spectrum analyzer or phase noise analyzer.

Hi Noel,

Can we use the two outputs of LMX2571, to connect to load. The LM2571EVM also has two outputs, can both these be used? Does these outputs the same signal?

Hi Athira,

When you use them simultaneously, they will output the same signal.

Hi Athira,

Try this:

1. reboot the PC

2. Run TICS Pro

3. plug-in the USB cable to the USB2ANY while pressing the BSL switch.

4. Then you should see the Update Firmware button.

Dear Noel,

I have followed up the instructions given by you. When I connect USB cable to USB2ANY and press the BSL I am getting dialogue boxes as below. Clicking OK on first box, it move to second dialogue box and then nothing proceeds. Is there any requirement for any driver or firmware loader software for USB2ANY?
