Timing Comparison For Data Transfer By Product

Timing comparison

Timing measurements are made with the radio modems in their default configuration. The measurements are made on a pair of modems performing a loopback test. Modem A is connected to the PC Com port and Modem B has a loopback connector.

The testing was performed using both 32 byte and 1 byte packets as the test data.
