VAVG

When video averaging is on, the take-sweep command (TS) resets the counter to 1, then initiates the number of sweeps speci￿ed for averaging. The counter is also reset to 1 whenever any command changes the measurement data. VAVG activates sample detection. Commands that follow VAVG are executed while the averaging routine is executing. However, if TS follows VAVG, subsequent commands after TS are not executed until the end of the averaging routine. Use VAVG to view low-level signals without slowing the sweep time. If a large averaging number is speci￿ed, video averaging can lower the noise ￿oor more than 1-Hz video-bandwidth ￿ltering can. Video averaging may also be used to monitor instrument state changes (changing bandwidths, center frequencies, and so forth) while maintaining a low noise ￿oor.
