Measurements with limit lines
During a measurement, the R&S FSH checks the trace after each frequency sweep for upper and lower
limit violations. If all measured values are within specified limits, PASS is displayed at the top in the
center of the diagram. FAIL is indicated even if only a single measured value (= pixel of the trace)
exceeds a limit value.
The automatic limit check can be switched off via softkey LIMITS ON/OFF. A limit violation can also be
indicated by an acoustic signal.
