Signal shape examples
The following are graphs of impulse and step signals
generated by the inverse FFT of the 8703A using a 20 GHz
Fspan. Electrical (dBe) and electro-optical (dBe) cases
are not presented since the signal shape is similar to the
lightwave examples shown.

45 Limited by maximum lightwave receiver input power, maximum
microwave power and system noise floor. Specified for a 20 GHz
frequency bandwidth, a normal window factor, a 10 Hz IF bandwidth,
a 16 averaging factor and after an appropriate calibration has been
performed (i.e., response & isolation calibration for optical tests,
response & match and isolation calibration for electrical-to-optical and
optical-to-electrical tests, or full 2-port and isolation calibration for
electrical test).
