Handover test of mobile terminal

Simulation of the transmission path between the base stations

[Application]

In mobile communication equipment such as mobile phone, the information should be transferred without breaking off when the transmission path is switched from a base station to next base station (called handover).

This handover test can be simulated using two or more units of MAT800 or MAT810.

[Difference and feature from conventional attenuator]

Scroll
Item Traditional attenuator MAT800/810 Remarks
Swiching method Mechanical Electronic  
Swiching speed 0 to 20ms/point 2μs/point Great improvement of time resolution
Attenuation step 1dB 0.05dB Great improvement of amplitude resolution
Spike at swiching Figure:Large spike
Large spike
Figure:No spike
No spike
The spike causes the communication error
Proguram memory Nothing 128kword built-in program memory The air state is stored
Program memory Nothing
  • FREE, BURST, GATE
  • Triffer for readout
  • Internal/external readout clock
  • Pause period of readout cycle
Various memory readout function
Software for maiking Nothing Making attenuation progrum can be done as easily as maiking arbitrary waveform. Standard accessory of MAT800/810
