FAQ 2010-09-14

Why does the voltage range setting on my U2300A switch to auto scale even though I had set the channel to a specific voltage range in the IVI-COM?
The auto scale function is one of the features of the U2300A Data Acquisition (DAQ) devices and is only supported under polling mode….

FAQ 2010-08-09

If I set Channel 1 of U2300A/U2500A with voltage range of 5V, I get a reading of 4.99968 when nothing is connected to the DAQ.
If you don't have anything connected to the DAQ and you do an acquisition out of it, the result…

FAQ 2010-08-09

Why is my acquired data for U2300A and U2500A shifted? eg. Column 2 data is in column 1, column 3 data is in column 2, and so on.
Install DAQ hardware driver version 1.05 and above.

FAQ 2010-08-09

What are differences for number of channels that can be displayed under continuous, polling and single shot for U2300A/U2500A?
There is no difference in the number of channels that can be displayed under the continuous, polling and 1 shot modes…

FAQ 2010-08-09

Will I still be able to use the digital I/O function of the U2355A or U2356A if I use this device with the U2802A Thermocouple input device?
No, the digital I/O function of the U2355A or U2356A Data Acquisition (DAQ) device will not be accessible if used with the U2802A device.

FAQ 2010-08-09

Why do we see unused port in U2300A/U2500A with similar waveform and frequency but with lower amplitude to its adjacent or close by used port?
It is recommended to ground all the AI connection that is not being used. If you have multiples of AI channels to be used, one good way is to have…

FAQ 2010-08-09

For U2300A/U2500A, why aren't all of the engineering units (EU) I chose for the different channels in the AMM displayed on axes of waveform graph?
The waveform graph can only display one unit on its axes regardless of the number of units chosen in the Measurement Manager (AMM)….

FAQ 2010-08-09

When using the U2300A/U2500A/U2600A Series Data Acquisition devices, how many modular chassis can the AMM application connect to?
The Measurement Manager (AMM) is designed to operate with one chassis at a time….

FAQ 2010-08-09

For U2300A/U2500A Series Data Acquisition (DAQ) devices, can the Measurement Manager (AMM) display in units other than voltage (v)?
Yes, the Measurement Manager (AMM) can display in units other than voltage (v)….

Is U2722A compatible with E5813A?
No

FAQ 2010-03-22

Is U2723A compatible with E5813A?
No

FAQ 2010-03-22

Is there any special setting that I need to do in Keysight VEE before using the U2300A or U2500A DAQ with it?
Yes. In fact it is the most important thing you need to set before using the DAQ with Keysight VEE. As most instruments uses MSB byte ordering, DAQ...

FAQ 2009-12-15

What does ENOB of 13.3 bit means in the specification sheet?
ENOB = (SINAD-1.76)/6.02 Overall Accuracy = ENOB (Effective Number of Bits)....

The DO port of U2100A and U2600A requires external power supply to be pumped into the port...

FAQ 2009-10-20

Can U2651A work with 3.3V input signal or not?
As long as there is a potential exceeding 10V and less than 24V between DIin and DIcom, the digital input should be able to observe the incoming signal as logic high...

FAQ 2009-09-29

How do I know what is the best sampling rate to use for my measurement?
Typically if you follow Nyquist theory, your sampling rate should be 2x the highest frequency of the incoming signal that you are measuring. However, we recommend that you use 5x...
