			User's Manual Datasheet
Overview
The Model 2680P AGC Data Logger is a stand-alone system configured to monitor the analog AGC outputs from thirty-two telemetry receivers. The hardware is composed of off-the-shelf items. The system is controlled by a 1U rack mounted PC with a 1U Keyboard/Monitor. The PC includes an 80 GByte Hard Disk drive (non-removable), a CD R/W drive for creating permanent archives of mission results, and integrated video and Ethernet 10/100/1000. The AGC voltages are sampled using a National Instruments PCI-6033E DAQ card, which includes a multi-channel programmable A to D. The A to D has 16-bit converters with a composite sampling rate of 100K Samples/Sec and input voltage range of ±10V. The system also includes 2 National Instruments BNC-2090 rack mountable interface panels, a SC-2056 cable adapter board with a rack mountable enclosure, and the cables necessary to connect these to the PCI-6033E card. The system can fit into 4U of rack space, and provides input for 32 channels.
System Software
The system's software includes Microsoft Excel 2003, and a custom GUI that allows a user to set up a sampling regimen and operate the system. The GUI can set up sampling tasks for up to 32 channels at a programmable rate of up to 10 scans per second. Each scan produces a log entry annotated by time read from the PC's system clock. In addition, if the system has network access to an Acroamatics TDP containing an Acroamatics IRIG Time Translator/Generator card (503V or 470M), you can add IRIG time annotation. The GUI acquires log entries directly to an ASCII comma separated text file. A post-acquisition dialog allows the transfer of the log entries from the CSV file to an Excel file, with capability to select a time windowed subset. The resulting .xls file can be written on the CD for distribution to range customers or accessed over the network as a remote file.
