Choose decibel equals to 1μW as amplitude unit.
6) [W]
Choose Watts as amplitude unit.
7) [V]
Choose Voltage as amplitude unit.
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】Auto Tune
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】Bandwidth
Sets the RBW (Resolution Bandwidth) and VBW (Video Bandwidth)
parameters of the analyzer. Pop out the setting menu includes
[RBW Auto Man], [RBW Mode Def Con],[VBW Auto Man],
[Average On Off], [EMI Filter►].
5.5.1 [RBW Auto Man]
Adjust the resolution bandwidth ranging from 10Hz-1MHz. Use
numeric key, step key or knob to switch resolution bandwidth. The
underline under Auto or Manual means Auto mode or Manual
mode. Press [Resolution Bandwidth Auto Manual] and hold it until
underline under Auto has been highlighted. Then the resolution
bandwidth is under auto coupling mode.
Key points:
⚫ Reducing the value of RBW will increase the frequency
