The Agilent 34972A 3-slot mainframe Data Acquisition/Switch with built-in 6½ digit DMM and 8 optional switch and control plug-in modules features (22 bits) of resolution, 0.004% basic dcV accuracy, and ultra-low reading noise. It measures and converts 11 different input signals: temperature with thermocouples, RTDs and thermistors; dc/ac volts; 2- and 4-wire resistance; frequency and period; dc/ac current. The 34972A has LAN, USB connectivity, Graphical Web interface for point and click monitor and control. It has scan rates of up to 250 channels/sec. The 34972A LXI Data Acquisition/Switch Unit is an LXI version of the 34970A. It replaces the GPIB and RS-232 interfaces with modern connectivity for a direct connection to your PC or Laptop. All readings are automatically time-stamped and stored in a nonvolatile 50,000 reading memory—enough memory to hold more than a week’s worth of data (20 channels scanned every five minutes). The nonvolatile memory holds your data even after power is removed, so you can use the 34970A/34972A to collect data at a remote location for later uploading to a PC. Or if you need even more memory, the 34972A’s USB port can be used to log data directly to a USB flash drive or to copy the data from the reading memory without being connected to a computer. The internal DMM gives you the flexibility to measure 11 types of inputs easily and inexpensively. The built-in signal conditioning and conversion routines turn raw inputs directly into real nformation. Each measurement channel is independently configurable, so you can set different measurement functions, scale factors and alarm limits, even on adjacent channels. Option 001 Delete Internal DMM.
