this mode is measurement throughput; extra time is required during initialization to perform the bandwidth
measurement.
• Manual: In this mode you can use the IF Bandwidth parameter to suggest a bandwidth for the system to use
during demodulation. The actual IF bandwidth that is used will try to be greater than this value, and at a point
where the PSA is optimized to produce fast, accurate results. In this mode measurement throughput is
increased because initialization bandwidth measurements are bypassed. Another use of this mode is to ensure
that the analyzer is behaving correctly for signals whose bandwidth is hard to measure (that is, low rate audio
signals).
• Minimal: This will choose the minimum IF bandwidth necessary to perform the modulation measurement.
The minimum bandwidth used is determined by the Low Pass Filter setting and is a value that is >
2xLowPassFilter. This mode usually works for most signals with a low modulation index. This mode will
increase measurement throughput because the analyzer can bypass the bandwidth measurement routines that
are performed at initialization for the Auto mode.
4.4.4.5.3 Average Number
Sets the number that will be averaged. After the specified number (average counts) have been averaged, the
averaging mode (termination control) setting determines the averaging action.
