Using the Spectrum Analyzer
Table 6 Relationship Between Span, Resolution Bandwidth, and Sweep Rate
Automatic Calibration
During operation, the Spectrum Analyzer pauses for approximately 2 seconds
every 5 minutes to recalibrate itself. This does not affect the accuracy of displayed
measurements, but does cause a brief interruption of the displayed information
during the process.
Setting Resolution Bandwidth and Sweep Rate
The resolution bandwidth and sweep rate are determined by the span setting, and
cannot be set independently.
These settings are listed in the following table.
Span
<50 kHz
<200 kHz
<1.5 MHz
<3 MHz
<18 MHz
<200 MHz
1 GHz
