5.3.7 [Preamplifier On Off]
Sets the status of preamplifier located at the front of the RF
signal path. Turning on the preamplifier reduces the displayed
average noise level in order to distinguish small signals from the
noise when working with small signals.
5.4 【Auto】 bottom softkey
Key access: [Auto] softkey at the bottom of the screen
Searches for signals automatically throughout the full frequency
range, adjusts the frequency and amplitude to their optimum and
realizes one-key signal search and auto setting of parameters.
Key points: some parameters such as reference level, scale, and
input attenuation may be changed during the auto tune.
5.5 【BW】 bottom softkey
Key access: [BW] softkey at the bottom of the screen
Sets the RBW (Resolution Bandwidth) and VBW (Video Bandwidth)
parameters of the analyzer. The setting menu includes [RBW Auto
Man], [VBW Auto Man], [EMI On Off].
5.5.1 [RBW Auto Man]
