Delta Sigma Delay on PCI-4461

[jmoses]

How long is the Delta Sigma Delay on the PCI-4461?  38 samples?  Is it the same for all sample rates?  Is it the same for the DAC as for the ADC?  Is accuracy good immediately after the Delta Sigma Delay is done, even if the analog signal is steep-sloped?

jmoses,

Take a look at the attached file, specifically the DSA_Help.chm.  Do a search for delta-sigma.  Results for ADC, DAC, ans Anti-Alias filters will appear.  This will give you more information on how it is done on the DSA devices.  Also, in the Anti-Alias filters section, you can see the susceptible sample rates and the resulting alias'.  I hope this helps.  Thanks and have a great day!
