keysight technologies u2300a series usb modular multifunction data acquisition devices data sheet
the keysight technologies, inc. u2300a series usb modular multifunction data-acquisition (daq) devices offer a high-performance pc data-acquisition solution. the u2300a series daq devices consist of two families: the basic multifunction daq comes in four models while the high density multifunction daq is made up of three models. the u2300a series daq devices applications extend across industrial and education environments. extending across industrial and education environments, the u2300a series daq with fast sampling rates is well suited for research and development, manufacturing as well as design validation designers. features C up to 3 msa/s sampling rate for a single channel C functions as a standalone or modular unit C easy to use: plug-and-play and hot swappable with hi-speed usb 2.0 C up to 384 channels when incorporated into u2781a keysight modular product chassis C easy-to-use bundled software for quick setup and data logging to pc C 12-bit or 16-bit analog-to-digital (a/d) resolution C 24-bit programmable digital input/output C self-calibration capability C compatible with a wide range of application development environments C usb 2.0 and usbtmc-usb488 standards introduction
3 high sampling rate the u2300a series daq devices can generate sampling rates of up to 3 msa/s for a single channel. when multiple channels are configured, the device can sample data up to 1 msa/s. the fast sampling capability allows users to perform intermittent detection easily. this is ideal when dealing with high density analog input/output signals especially when juggling between different input ranges and sampling requirements. flexible standalone or modular capability the u2300a series daq devices are uniquely designed with the flexibility to function as a standalone unit or as a part of a modular unit. when used together with the u2781a modular product chassis, the devices has the capability to sup - port up to 384 channels. flexible system and control options with polling and continuous mode the u2300a series daq devices have two modes, polling mode and continuous mode. selecting continuous mode enables you to acquire data continuously once the trigger signal is received. arbitrary waveform designed to support arbitrary waveforms, the u2300a series allows you to generate arbitrary waveform via the keysight measurement manager application software or scpi commands. burst mode equipped with the burst mode, the enhancement feature enables simultaneous mode for analog input acquisition. now can you can perform sampling measure - ment up to the highest possible speed of the daq. trigger sources u2300a series offers various trigger options from immediate trigger (none), analog/external digital trigger, system synchronous interface (ssi)/ star trigger and master/slave trigger sources. these entire trigger options has the capability to configure trigger sources during a/d and digital-to-analog (d/a) operations. selecting the slave trigger and ssi/star trigger are recommended when the usb modules are used together with the keysight u2781a usb modular product chassis. predefned function generator aside from supplying dc voltage, the two analog output channels are capable of generating common and predefined waveforms such as sinusoidal wave, square wave, triangle wave, sawtooth wave and noise wave.

17 thermocouple input mode in thermocouple input mode, the u2802a can acquire up to 100 mv input signals. each channel includes an instrumentation amplifier and a 4 hz low-pass filter. the low-pass filter removes unwanted noise from the thermocouple wires to obtain accurate measurement data. voltage input mode alternatively, you can select separate voltage input modes for each channel. the channel will be set to bypass the amplifier and filter, allowing up to 10v input signals to be directly routed to the daq device analog input. the bandwidth in this mode is more than 500 khz. zero mode in zero mode, the positive and nega - tive inputs of the instrumentation amplifier are shorted together. the voltage measured in this mode corresponds to the offset voltage of the channel. you can subtract this offset voltage from subsequent thermocouple mode measurements to increase measurement accuracy. this mode is only applicable in thermo - couple mode. thermocouple compatibility the u2802a is compatible with a wide range of standard thermo - couple types defined in the nist its-90 thermocouple database. this includes types j, k, r, s, t, n, e, and b. open thermocouple detection the u2802a includes open ther - mocouple detection circuitry to indicate the presence of an open thermocouple. calibration eeprom the u2802a gain and offset calibra - tion factors for each channel are stored in the eeprom during fac - tory calibration and can be retrieved prior to taking measurements. this on-board eeprom also stores the module id, serial number, and date of calibration for your reference. a sec - tion of the eeprom is also allocated for you to save your calibration data. restoring factory calibration using the amm software, you can easily restore the u2802a calibration data from your settings to the original factory settings. 17
