Keysight DAQM907A Multifunction Module (Digital I/O, Totalizer, Analog Output)Key Features At A Glance 3-slot mainframe with built-in 6½-digit (22-bit) internal DMM and 0.003% basic 1-year DC voltage accuracy Scalable from 4 to 120 channels using nine switch, RF, and control plug-in modules Measures 14 input signal types: temperature, DC/AC volts and current, resistance, frequency, capacitance, and strain Scan rates up to 450 channels/s with 1-million-reading nonvolatile, time-stamped memory LAN and USB 2.0 standard for PC connectivity and automation; DAQ973A model adds built-in GPIB (IEEE-488) 4.3-inch color display with numeric, bar graph, trend chart, and histogram measurement views Code compatible with 34970A/34972A; SCPI with C, C#, Visual Basic, and Visual Studio drivers BenchVue DAQ software included for PC-based logging and time/frequency-domain analysis The Keysight DAQ970A/DAQ973A is a data acquisition system built around a compact 3-slot mainframe with a built-in 6½-digit (22-bit) internal DMM. The measurement engine from a high-performance benchtop DMM is embedded inside the mainframe, combining proven measurement performance, universal inputs with built-in signal conditioning, and modular flexibility in a single low-cost package. It delivers 0.003% basic DC voltage accuracy, ultra-low reading noise, and scan rates of up to 450 channels per second, giving an engineer both the speed and the accuracy needed for demanding acquisition work.Configured with a 20-channel relay multiplexer, the system becomes a powerful, low-cost data logger for characterization applications, and it also serves as a data acquisition front end for automated test. Typical data-logging and monitoring uses include environmental chamber monitoring, component inspection, benchtop testing, process troubleshooting, and temperature profiling. It supports both the R&D engineer characterizing a new design and the manufacturing engineer building a test system or troubleshooting a process. The 40-channel single-ended multiplexer adds density for applications such as battery test and component characterization. 2.0 V (TTL) Vout(L) < 0.8 V @ Iout = -400 mA Vout(H) > 2.4 V @ Iout = 1 mA Vin(H) max < 42 V with external open drain pull-up Alarming Maskable pattern match or state change Alarm sampling speed 4 ms (max) Latency to alarm output 5 ms (typical) Read/write speed 95/s Totalizer Characteristics Max count 2^26 - 1 Totalize input 100 kHz (max), rising or falling edge, programmable, min H or L time 5 µs Signal level 1 Vp-p (min), 42 Vpk (max) Threshold 0 V or TTL, jumper selectable Gate input TTL-Hi, TTL-Lo, or none Count reset Manual or Read + Reset Read speed 85/s Important: The internal DMM input section is optically isolated and shielded from the earth-referenced circuitry and computer interface, providing up to 300 V of input isolation. Important: The DAQ970A/DAQ973A mainframe requires at least one low-frequency multiplexer module to make measurements: only the DAQM900A, DAQM901A, DAQM902A, and DAQM908A modules connect to the internal DMM. Modules are ordered separately ('buy only what you need—and add more modules later as your application grows'). Important: Up to three modules, in any combination, can be inserted into a single mainframe. Important: The DAQM905A RF Multiplexer uses SMB connectors; a standard set of (10) BNC-to-SMB adapter cables is provided with each RF module for BNC connections (2 GHz bandwidth via SMB, 1 GHz via the BNC-to-SMB adapters). Important: On-module screw terminals accept wire sizes from 16-gage to 22-gage; twenty-gage wire is recommended for high channel count applications. Important: On the DAQM902A, user-provided shunt resistors are required for current measurements. Important: All VAC ranges are limited to 8 x 10^7 Volt-Hz.Recommended pairing: add the DAQM909A 4-channel simultaneous-sampling digitizer to use the included BenchVue DAQ software for frequency-domain (FFT, THD, THD+N, SINAD) and time-domain measurements.Recommended pairing: listed accessories include the 34307A J-type thermocouples and 34308A 10 kΩ thermistors for temperature measurements and the 11062A Kelvin clip set for resistance measurements.About this New unitThis is a brand-new, factory-sealed unit, supplied exactly as it arrives from the manufacturer and backed by the full manufacturer warranty.
