the {Start Freq} and {Stop Freq} under scan table if Auto is selected.
Navigating the menu system
Before starting the demonstration, it is important to understand the MXE’s menu
structure. The meters menu is for making a single frequency measurement with up to
three detectors updated simultaneously. The frequency of meters represents the current
frequency of EMI receiver mode.
The scan and (re) measure menus apply to scan sequence. Scan sequence is very
important for understanding the philosophy of MXE operation because it aligns with
the CISPR test flow. The MXE is designed with clearly independent settings for meters
(Region 1), scan (Region 2), and (re) measure. The current values for the Region 1
and Region 2 settings are presented in each region. Figure 2 shows the EMI test flow
recommended by CISPR 16-2-3. Scan only, search only, and (re) measure are the
settings of scan sequence on the MXE corresponding to pre-scan, data reduction, and
final measurement of the EMI test flow. Table 1 lists the menu path of the sets of settings
for meters, scan, and (re) measure respectively.
All keystrokes surrounded by [ ] indicate front panel hard keys and keystrokes surrounded
by { } indicate soft keys on the side of display.
