Problems solved by technology

The disadvantage of JP2007-116329A is that in order to calculate the data throughput, the acknowledgment packet must be received, therefore, the quality of the corresponding return channel must affect the throughput measurement of the downlink path (English: downlink) or the throughput measurement of the uplink path (English: uplink) throughput measurement

Embodiment Construction

[0025] figure 1 A schematic circuit diagram of an exemplary embodiment of a measuring unit 1 for measuring transmission parameters of a device under test 2 according to the invention is shown. The measuring unit 1 comprises a control unit 3 , a transmitter and receiver unit 4 and an evaluation unit 5 . The transmitter and receiver unit 4 is connected to the control unit 3 via a first connection 6 . For example, this first connection 6 may be a LAN connection. The transmitter and receiver unit 4 is also connected to the device under test 2 via a transmission channel 7 . The device under test 2 is then connected to the evaluation unit 5 via the second connection 8 . For example, the second connection 8 can be a LAN connection, a USB connection (English: universal serial bus; German: universelle serieller Bus) or a PCMCIA connection (English: personal computer memory card international association; German: Personalcomputerspeicherkarte, internationale Vereinigungskarte). Test...

Abstract

A measuring unit for measuring transmission parameters of a device under test, comprising a control unit, a transmitter and receiver unit and an evaluation unit. The transmitter and receiver unit is connected via a first connection to the control unit and via at least one transmission channel to the device under test. The device under test is connected via a second connection to the evaluation unit, wherein, for the measurement of the transmission parameters of the device under test, control-data packets and test-data packets are transmitted separately between the control unit and the evaluation unit, and wherein a transmission channel for the test-data packets can be disturbed in a targeted manner.

Description

technical field [0001] The invention relates to a measuring unit and a method for measuring transmission parameters of a device under test. Preferably, the measurements of transmission parameters include throughput measurements, delay measurements and round-trip delay measurements (German: ), jitter measurements and packet error rate measurements, where the device under test is connected to the measurement unit via a simulated radio transmission channel. Background technique [0002] Portable electronic devices such as mobile phones, electronic organizers and notebook computers, but also fixed-use devices such as WLAN routers (English: wireless local area network; German: drahtloses lokales Netzwerk), today cover an increasing number of communication standards . For example, in addition to the GSM standard (English: global system for mobile communications; German: System zur weltweiten drahtlosen Kommunikation) and the UMTS standard (English: universal mobile telecommunic...
