Agilent U2500A Series
USB Modular Simultaneous Sampling
Multifunction DAQ Devices
Data Sheet
Introduction
Features
• Simultaneous sampling with
up to 2 MSa/s sampling rate
for each channel
The Agilent U2500A Series USB modular simultaneous sampling multifunction
data acquisition (DAQ) devices are high-performance modules that consist of
three models – the U2531A, U2541A and U2542A. The U2500A Series has up to
four channels with resolutions of 14-bit and 16-bit. The U2531A can sample up
to 2 MSa/s for each channel with a resolution of 14 bits, while the U2541A and
U2542A can sample up to 250 kSa/s and 500 kSa/s for each channel
respectively with a resolution of 16 bits.
• Multifunction DAQ solution AI, AO, DIO, counter
• Dedicated ADC per channel
Various features of the U2500A Series
• 14-bit or 16-bit resolution
• Quick and easy USB setup
• 24-bit programmable digital
input/output
• High sampling rate of up to 2 MSa/s for each channel
• Functions as a standalone or
modular unit
• Flexible standalone or modular capability that enables lower startup cost
• Dedicated analog-to-digital (ADC) that allows simultaneous sampling of data
• Supports SCPI and IVI-COM
• SCPI and IVI-COM supported with a wide range of ADE compatibility that
minimizes work time and increases software choices
• Compatible with a wide range
of ADEs
• Easy-to-use application software and command logger function for easy SCPI
command conversion into snippets of VEE, VB, C++, and C# code
• Easy-to-use bundled software
• Command logger function
• USB 2.0 and USBTMC-USB488
standards
High sampling rate of up to 2 MSa/s
The U2500A Series provides a high analog input sampling rate coverage of up to
2 MSa/s for each channel. The high sampling rate coverage offered is ideal for
transient signal applications such as sonar analysis.
Simultaneous sampling of data
The U2500A Series has dedicated ADCs that enable simultaneous signals
acquisition, which makes the U2500A Series suitable for your phase-sensitive
applications.
