| Test setups |
radar under test (RUT) is directly connected to the R&S®SMW200A (+ R&S®FSW) via cable |
conducted test |
| |
RUT and R&S®SMW200A (+ R&S®FSW) are equipped with antennas and connected via air interface |
over-the-air (OTA) test |
| Radar RX power setting |

Simulation setup
|
| System latency calibration |
R&S®SMW-K78 measures the internal system (R&S®FSW + R&S®SMW200A) latency automatically
(only available in transmit signal mode: external baseband via R&S®FSW + R&S®SMW-B10) |
automatic |
| |
user measures internal latency with external equipment (e.g. scope) |
