15.1 Requirements on TEMS Investigation PC

15.1.1 Hardware

15.1.1.1. TEMS Investigation

TEMS Investigation 23.2 is designed to run on a standard PC and interfaces with the connected devices mainly through USB or serial ports.
Processor and RAM requirements are strongly dependent on what external devices are connected and what tasks they perform. The recommended minimum configuration is: Pentium T7200 or AMD TL-58 class CPU with dedicated graphics card, preferably from ATI or nVidia; 1 GB RAM. Please note that it is not advisable to collect data with more than one device, or to collect data in an LTE or HSPA network, using this configuration. A dedicated graphics card is absolutely required for such more demanding tests.
LTE data service testing at high throughput rates (above 50 Mbit/s) requires a very powerful PC processor, for example a second-generation Intel Core i5 or comparable Intel Core i7.
For testing with a large array of connected devices (for example, 6–8 devices plus GPS), an Intel Core i7-nnnQM/XM, Intel Core i7-2nnnQM/XM, or equivalent processor is necessary.

15.1.1.2. Other hardware requirements

One USB port for each user terminal

One USB port for each stand-alone AQM module

USB port for PCTel scanner (except models requiring serial connection)

USB port for equipment case

USB port, Bluetooth port, or serial port for GPS

Serial port for PCTel SeeGull LX dual-band/single-band scanner

Ethernet port for Rohde & Schwarz scanner

ExpressCard/34 slot or PC Card slot for any data card user terminals

Sound card and loudspeakers for event audio indications

Enough disk space to accommodate temporary files created during installation (at least 1 GB), logfile recording, and logfile analysis.

If using a USB hub, the hub must have an external power supply.

Note: During drive testing, it must be ensured that the PC and all devices connected to it have adequate power supply for the duration of the test. See the Device Configuration Guide, chapter "Read This Before You Start Drive Testing".
