The Level Meter view allows you to make selective measurements at a defined frequency (Fcent) e.g. for monitoring the field strength of a communications channel. The channel bandwidth (CBW) for this can be set in the range 25 Hz to 40 MHz (zero span mode). Steep filters enable precise separation of adjacent channels. The Peak detector values (for brief pulsed signals) and RMS detector values (for variable signals) are displayed simultaneously. An advantage of Level Meter view is that the measurement is in real time and there are no time gaps.
