38 • Front Panel Menu System ACO-4500 User Guide (v3.0)
The signal bars that appear in the upper section of the display are arranged in the following order (from left to
right):
• Channel 1 Primary
• Channel 1 Backup
• Channel 2 Primary
• Channel 2 Backup
• Channel 3 Primary etc.
The maximum number of signal bar pairs displayed will be limited to the “Number of Channels” setting elsewhere
in the Menu System.
• If the Channel Type for a particular channel is set for “No Measurement”, then the signal bars will not appear in
the relevant position on the display.
• If the input(s) for a particular channel is/are missing, the signal bar(s) for that channel will be displayed at
minimum height.
• You may have more channels with signals connected, but these will not be displayed.
The amplitudes of the bars are scaled, so that signals of different nominal amplitudes are all shown with
approximately the same height bars on the display. So, for example, if a 600mV TriSync signal is connected to a
channel set as Color Black (300mV), the relevant signal bar will be significantly higher than for any other channel
with the correct signal present. Similarly, Color Black connected to a TriSync channel will appear significantly
lower in amplitude.
The widths of the bars in each channel pair are different - the Primary bar is wider than the Backup bar.
The bottom line of the menu displays the actual detected levels of the Primary and Backup input signals for the
currently selected channel.
Channel # = POK X BOK X
The options in the field “#” are: 01 up to the “Number of Channels” setting.
Upon entering this menu, simply rotating the rotary control allows the user to select a channel to display. Press the
push-button to return to the Main Menu.
The options displayed in the fields “POK” or “BOK” are:
• PErr / BErr Primary / Backup - Error Detected
• POK / BOK Primary / Backup - No error detected.
The values displayed in the fields “X” represent the actual detected signal levels of the selected input channel.

Figure 7.6 provides an example of the Channel Configuration menu.

The Channel Configuration Menu allows the user to configure each BNC channel to monitor the incoming signal
according to the selected signal type.
