5.3.5 [Ref Offset]
Assigns an offset to the reference level to attempt to compensate for gains or losses generated between the device under
measurement and the analyzer.
Key points:
•
The changing of this value changes both the readout of the reference level and the amplitude readout of the marker, but
will not impact the position of the curve on the screen.
•
You can modify this parameter using the numeric keys.
• This offset use dB as absolute unit, will not change with selected scale and unit.
5.3.6 [Ref Unit►]
Sets the unit of the Y-axis to[dBm], [dBmV], [dBuV], [V] or [W]
Key points:
1) [dBm]
Choose decibel equals to 1mW as amplitude unit.
2) [dBμW]
Choose decibel equals to 1μW as amplitude unit.
3) [dBpW]
Choose decibel equals to 1pW as amplitude unit.
4) [dBmV]
Choose decibel equals to 1mV as amplitude unit.
5) [dBμV]
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 resolution, but may also cause sweeps to take longer (Sweep
Time is effected by a combination of RBW and VBW when it is in Auto mode).
• RBW decreases with the span (non-zero span) in Auto RBW mode.
5.5.2 [RBW Mode Def Cont]
Adjust resolution step mode, resolution mode can be set to 1-3-5, Default or Continuous mode.
