Tuesday, July 07, 2020, 17:43, Carla Babcock, ITE, Development, TM4, , RF tests on new IG-LIS wiring
|
Tested RF from RF driver into new IGLIS wires at ITE. Used 5V, 1MHz (2MHz setting because of internal halving issue).
As expected there was a very slight mismatch visible (original cable ~ 68 Ohms, new cable ~ 53 Ohms).
The matching resistor will be changed and it will be retested. |
