Spectrum Analyzer
Measuring a Low−Level Signal
This section provides information on measuring low-level signals and
distinguishing them from spectrum noise.
This chapter is divided into the following sections:
“Reducing Input Attenuation” on page 89
“Decreasing the Resolution Bandwidth” on page 91
“Trace Averaging” on page 93
CAUTION Ensure that the total power of all signals at the analyzer input does not
exceed +33 dBm (2 watts).
Basic Assumption
The material in this section is presented with the assumption that you
understand the front and rear panel layout, and display annotations of
your analyzer. If you do not, refer to the Measurement Guide “Front and
Rear Panel Features”.
