Error -200077 occurred at DAQmx Timing (Sample Clock).vi:4730001[Property: SampClk.Rate Requested Value: 50.0e3 Maximum Value: 5.0e3]

Hello,

I am currently working with the NI USB-6002 device and have been developing a LabVIEW VI for analog output generation. Specifically, I started with the example VI provided in LabVIEW titled "Voltage (non-regeneration) - Continuous Output.vi". I modified this example to enable signal regeneration using a buffer and incorporated an additional basic function generator into the VI. The purpose of this modification is to add two signals together and send the combined output to an oscilloscope.

However, I am encountering an issue with the sampling rates. The signal transmits correctly at rates below 5000 S/s, but when I attempt to use a sampling rate above 5000 S/s, I receive the following error:

[Error -200077 occurred at DAQmx Timing (Sample Clock).vi:4730001]

I have tried various configurations within the DAQmx Timing block in the VI, but the error persists. Could you please advise on how to resolve this issue?

Additionally, while reviewing the device datasheet, I came across the term "Maximum update rate - 5 kS/s simultaneous per channel." I suspect this might be related to the hardware limitations of the NI USB-6002. If this is the case, is there any alternative approach or configuration that would allow me to output an analog signal at a higher sampling rate, such as 50 kS/s?

Yes.

Not with your NI6002.

When you need higher sample rates then you need to choose another hardware. (You should have selected hardware depending on your requirements!)

thank u for your replay !,  I believe, I should start looking for the new NI-hardware. 

by the way, in my LabVIEW. when i place my DAQ assistant block in my block diagram and click on it. there is no configure tab is opening. I am using LabVIEW 2019 version as i have the licence key to operate it, and ni-daqmx driver of version 2025 Q1. What is the main reason. is it regarding version or some setting to do in my LabVIEW?

i want to use DAQ assistant for the purpose of triggering on the acquired signal.

That is the main reason: you are using LabVIEW2019 with DAQmx2025!

As can be read here DAQmx only supports the current LabVIEW version (2025) and 3 years before (down to 2022). You need to install a different/older DAQmx version that supports your LabVIEW version!!!
