WebMay 16, 2016 · The FPGA processing bandwidth is the sample rate provided by the ADCs and DACs on the USRP motherboard. This sets the hypothetical maximum digital bandwidth of a system based on the USRP. For example, the FPGA of the USRP X300/X310 sends and receives samples at 200 MS/s from the DACs and ADCs respectively. WebSample Block Diagram Notes Use only one Wait For Next Sample Clock VI within a LabVIEW loop. If you have multiple hardware-timed I/O tasks within the same LabVIEW loop, you can connect the Wait For Next Sample Clock VI to any one hardware-timed single point task within that loop.

WebOct 17, 2024 · One of the most important aspects of a sensor measurement system is the degree to which you can correlate in time the data acquired from multiple channels. If your data is not appropriately correlated in time, or synchronized, then your analysis and conclusions from your test data are inaccurate. WebSep 10, 2024 · The Read Express VI samples at around 70 Hz for every trial. – btrink25 Oct 7, 2024 at 19:40 If 70 Hz is the current loop rate, then other code is also running and consuming time before the while loop executes again. The input to Wait Until ms Multiple won't have an effect on your program until it throttles the loop rate further.

WebA bigger problem will be achieving the 500MHz internal clock that you need for the ADC IO. You don’t need to run the entire FPGA on it, but even achieving this speed for the IO logic is a challenge. At these speeds counters larger than a few bits stop working due to the carry propagation delay. WebJul 11, 2024 · Let’s assume a 100MHz sample clock rate for the sake of discussion. If you choose to represent both phase and frequency step with N=32 bits, you can represent any frequency between zero and your sample clock rate divided by two, with a precision given by: frequency_precision_hz = sample_clock_rate_hz / 2^N

WebNov 3, 2009 · That means the freq of the signal generated is 1Hz Hence you can come up with the equation that Frequency of signal = (sample rate)/ (# of Points) which means if you increase your sample rate to say10KHz, the frequency of the signal generated will be 10K/1000 = 10Hz.

WebChanging the Master Clock Rate. The master clock rate feeds the RF frontends and the DSP chains. Users may select non-default clock rates to achieve integer decimation rates or interpolations in the DSP chains.
