RE: RE: Looking for a Satellite Link Emulator
We are using the ADTECH SX/12 now as link simulators (up to 8Mbps).
A copule of points:
1. They simulate delays and BER, distributed uniformly or programmable into
bursts.
If you need simulation of packet loss, you need to implement this
yourself.
2. The ADTECH uses an internal buffer to do the delays. We have found that
if you
set it to a high delay, the BW it can handle is limited and vice-versa,
or you simply
lose data silently.
