Handover test of mobile terminal

Simulation of the transmission path between the base stations


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]

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
  • 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
