What causes overload on a network analyzer?
Excessive power applied to one of the receivers causes overload. Specifically, on the 8753D or 8753E the error message is:
"OVERLOAD ON INPUT A,B,R; POWER REDUCED" indicates that you have exceeded approximately +14 dBm at one of the test ports. The RF output power is automatically reduced to -85 dBm. The power trip function has been activated. When this occurs, reset the power to a lower level, then toggle the "SOURCE PWR on OFF" softkey to switch on the power again.
