Hi,
why does the PCGU1000 allow 25MHz for sweeping whil only having a frequ range up to 2MHz.
Íf I generate a sweeping from 10Mhz to 10Hz how preciseis the frequency?
I need to knwo it as I have to decide if the unit is the right one for integrating it in our systems.
We need to seep around frequencies up to 10Mhz with +/1 10Hz for around 10 sec each. Is this possible?
With best regards,
Marcus Schmieke

[quote]Íf I generate a sweeping from 10Mhz to 10Hz how preciseis the frequency?[/quote]There is 44 bit phase increment register used in the generator. The frequency setting is very accurate.
The accuracy is same as the crystal oscillator accuracy of the generator +/-100 PPM.

Thank you for the answers.
Until which freuquency is there a somehow acceptable square signal?

The square wave looks quite “square” up to about 5 MHz.
Rise/fall time about 17ns.
Thank you. Thats fine for us.
