5.5.3 [VBW Auto Man]
Sets the desired video bandwidth in order to remove the band noise. Set the video resolution displays in function area,
ranging from 10Hz to 1MHz by sequence step. You can modify this parameter by numeric key, step key or knob. The
underline under Auto or Manual means Auto mode or Manual mode. Press [VBW Auto Manual] and hold it in manual until the
underline highlighted under Auto to return auto mode.
Key points:
• Reducing the VBW to smooth the spectrum line and differentiate small signals from the noise. However, this may cause a
longer sweep time. (Sweep Time is effected by a combination of RBW and VBW when it is in Auto mode).
• VBW varies with RBW when it is set to Auto.
5.5.4 [Average On Off]
Trace average function. It doesn’t need narrow VBW to implement smooth trace. This function set the wave detector to
acquisition mode, continuously get average of the trace to smooth it.
5.5.5 [EMI Filter►]
Pop out the menu for EMI measurement bandwidth.
1) [EMI Filter On Off]
Turn on or off EMI measurement resolution bandwidth.
2) [1MHz]
Set EMI measurement resolution to 1MHz.
3) [120kHz]
Set EMI measurement resolution to 120kHz.
4) [9kHz]
Set EMI measurement resolution to 9kHz.
5) [200Hz]
Set EMI measurement resolution to 200Hz.
6) [Return]
Return to the previous menu.
5.6 [Trace]
As the sweep signal is displayed as a trace on the screen, you can set parameters about the trace using this key.
The analyzer allows for up to five traces to be displayed at one time, and press this key to check the menu for trace. It in-
cludes [Trace 1 2 3 4 5], [Clear Write], [Max Hold], [Min Hold], [Blank], [View], [Operations►] ,[ 1 ↔ 2], [ 2 - DL → 2], [ 2 ↔ 3],
[ 1 → 3] and [ 2 → 3].
5.6.1 [Trace 1 2 3 4 5 ]
Select trace, the analyzer offers 1, 2, 3, 4, 5 trace. The selected trace and corresponding status menu will be underlined.
5.6.2 [Clear Write]
Refresh current curve and display the analyzer trace.
5.6.3 [Max Hold]
Maintains the maximum for each point of the trace. It continuously receive scan data and select positive peak value detect
mode.
5.6.4 [Min Hold]
Maintains the minimum for each point of the trace. It continuously receive scan data and select negative peak value detect
mode.
5.6.5 [Blank]
Clear the trace on screen. But the trace stock will keep still without refreshing.
