Auto-Amplitude Discrimination; Maximum Input Signal Power; Dbm To Volts Conversion - HP 5340A Operating And Service Manual

3-19. Auto-Amplitude Discrimination

3-20. This feature allows the counter to select and measure the signal with the largest amplitude
in the 250
in amplitude than any other signal present. Although 20 dB is the guaranteed specification,
typical operation
criminating against harmonics, and spurious signals.

3-21. MAXIMUM INPUT SIGNAL POWER

3-22. The 5340A will function within specifications for signal inputs up to +7 dBm (5.012 milli-
watts or 0.5006 volts into 50-ohms). Under no circumstance should the input level exceed 1-watt
damage to the internal samplers may occur and these are quite expensive to replace. Measure-
ments from +7 dBm to +30 dBm are not recommended because false harmonic locks and readings
may occur. When signal levels exceed
maximum input level is the total
power levels with conversions to volts and dBm.
