pclk resolution

[Frankmesa]

I have a 6534 card. I know it goes to 20Mhz, but does anybody know the resolution of the internal pclk.

Hi,

I am confused as to what type of spec you are looking for. Resolution is typically used to define ADC and not something you find with Digital boards. Could you please explain in more detail what information you are looking for? All of the specs are defined in the User Manual:

I hope this helps, and have a Great Day!

Sorry for the confusion. I'll be using a range of internal pclk frequences and was trying to see what the resolution is.

Example:
Sweep 1Khz to 20Mhz at 1hz increments [does the internal Pclk have this resolution 1hz? .5 hz? 10hz?

Hello,

The 6533 and 6534 products have an internal timebase of 20 MHz. The frequencies that this board can generate are 20 MHz/n where n is an integer. So, you can hit 20 MHz, 10 MHz, 6.67 MHz, 5 MHz, etc. If you want 1 Hz resolution at this range of frequency, you may want to take a look at the PXI-5404. You can generate clock frequencies up to 100 MHz with 1 microHz resolution.

You can then export the clock from the 5404 to the PClk of the 653x board.

I hope that helps,
