I have two quick questions:
1) Is the BNC-2111 compatible with the PCIe-6363.. Although the PCIe spec page lists the BNC-2111 as a possible accessory, the BNC-2111 manual doesn't contain any info on the physical connection with a 6363(that I can see).
2) Will the combination of BNC-2111 and PCIe-6363 allow me to accurately measure a freq of 190476Hz. Right now I'm musing the SCB-68 alpha to generate an AO(square wave) thats wired to an SCB-68A AI. Using DAQmx Express VIs to display the wave, then Get Frequency from the wave form. Ultimately, I'll be using these devices to perfom an OSCAL function, and I need to be able to measure a frequency of 190476Hz(+/- 300Hz). Right now I question the accuracy of the AI wave to Freq sequence that has to be used with the SCB-68A. Could be a grounding issue but not sure yet. Based on what I'm experiencing, the PCIe does not support direct frequency reads if using the SCB-68A. Is this correct?
