FAQ 2010-08-30

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 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

What is the clock rate for Digital Inputs(DI) and Digital Outputs(DO) of U23xxA and U25xxA USB Data Acquisition?
The DAQ DIO is not meant to measure DI with clock rate precision or to control frequency of digital output

FAQ 2010-07-18

What is the temperature coefficient supported by the 34970A for RTD temperature measurements?
The 34970A supports PT100 RTD's with an alpha=0.00385, RTD's with alpha=0.00385, or alpha=0.00391.

FAQ 2010-05-16

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

Can strain gauges be measured with the Keysight 34970A?
The 34970A can measure strain gauges using 4-wire ohms measurements and return the strain value using the math formula Mx+B.

FAQ 2009-11-18

What is the main difference between the digital output (DO) of the U2100A, U2600A, U2300A and U2500A?
The DO port of U2100A and U2600A requires external power supply to be pumped into the port...

FAQ 2009-10-20

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...

FAQ 2009-09-29

How Do I Measure Resistance With A 3-Wire Device?
If you are using a 3-wire device (ie. 3-wire RTD), to measure it accurately, you have to first measure the resistance of R1+R2+Rm then subtract the resistance you measured of R2+R3.

FAQ 2009-09-28

Why do I receive an error message below ?
Generally, if you are sampling at 60kSa/s and above, you should use high sampling mode to acquire data. This is just a rough guideline. If you encountered this message even when....

FAQ 2009-08-06

How can I remotely connect to all my USB DAQ devices, Digital IOs, and card cage?
Please make sure that your remote PC (which is connected to all your USB instruments) is connected to the same network as yourself. However, your remote PC cannot be connected...

FAQ 2009-08-06

Can both Analog Input and Analog Output function at the same time?
Yes, both Analog Input and Analog Output can function at the same time. However,….

FAQ 2009-02-04

Can I remove a 100V or above common mode voltage when making thermocouple measurements using the 34970A?
Yes, for less than 300V peak by setting the internal DMM's integration time to a value of 1 or larger number of power line cycles.

FAQ 2007-01-10

Why I am getting incorrect results when measuring the temperature of a switch with the 34901A?
If you are doing thermocouple measurements with an AC signal, you need expect noise in the readings. You can reduce this noise by applying the common mode noise rejection.

FAQ 2007-01-09

34970A: What is Burden Voltage?
Connecting the internal DMM in series with a test circuit to measure a current, a measurement error is introduced.

FAQ 2006-08-29

What temperature reference junction choices do I have for making thermocouple measurements with the Keysight 34970A?
You can use an internal, external, and fixed reference.

FAQ 2006-08-29

Can I configure the 34970A for 4-wire resistance, 4-ohms, and/or 4-wire scan?
Yes, the 34970A can be configured for 4 wire resistance, 4 wire RTD or 4 wire external scanning.

FAQ 2006-08-29

How do I make a measurement from the front panel with the Keysight 34970A?
This FAQ describes how to setup for a measurement from the front panel using the thermocouple shipped with the 34970A and a 34901A/34902A/34908A module card.

FAQ 2006-02-02
