The “RF Level Recorder” tool
The “RF Level Recorder” tool allows you to check the reception quality of your wireless microphone system. You can record the field strength of any transmitter in any area of the stage and, if necessary, optimize the antenna positions using the detailed graphical representation provided by the tool.
Calling up the “RF Level Recorder”
- In the system window, click on the “Tools” tab.
- Double-click on the “RF Level Recorder” icon.
The “RF Level Recorder” window
1 Toolbar
2 Selection area
In the selection area, you can:
- select a stationary receiver (see Selecting a stationary receiver for the recording)),
- preset the start time for the recording (see Presetting the start time for the recording) and
- set the recording duration (see Setting the recording duration – “RF Level Recorder” only).
3 Recording bar
4 „RF Level” window (display range of up to 40 dB max.)
This window displays the field strength of the receiver’s diversity channels over a defined period of time.
The measured values of the field strength “RF Level” are displayed as colored bars over the defined measuring duration. Field strength levels of up to 40 dB max. can be displayed.
- Red: Diversity channel Antenna I/Antenna A
- Green: Diversity channel Antenna II/Antenna B
- Yellow: Squelch threshold
- White: Muted
5 “Memory”, “Diversity” and “Rec Time” displays
“Memory” display
The “Memory” display is only shown if a recording from the temporary memory is displayed (see Temporarily saving recordings and comparing them).
“Rec Time” display
The measuring duration is shown together with the current time on the x-axis of the “Rec Time” line. The measuring duration depends on the setting made under “Duration” (see Setting the frequencies – “RF Spectrum Analyzer” only).
“Diversity” display
The colored bars in the “Diversity” line display the active diversity section.
- Red: The measured field strength of “Antenna I” / “Antenna A” is higher than that of “Antenna II” / “Antenna B”
- Green: The measured field strength of “Antenna II” / “Antenna B” is higher than that of “Antenna I” / “Antenna A”
- White: The measured field strength of both antennas is below the squelch threshold; the receiver is muted
Example:
At 15:00 o’clock, the bar is green, i.e. antenna I/A is active. At 16:00 o’clock, the field strength of antenna II/B is stronger. Antenna II/B becomes active and the bar in the “Diversity” line is displayed in red.
6 Display of the current date and time and the set recording duration
The current time, the date and the recording duration are displayed. Time and date are taken from the operating system. The recording duration is set under “Duration” (see Setting the frequencies – “RF Spectrum Analyzer” only).
7 “Comment” field
Important occurrences can be marked and commented. The markers are displayed as vertical blue lines. A blue flag appears above them.
When you click on a marker, the line and the flag turn to orange. When you move the mouse pointer over a marker, a box will appear above the marker, indicating the time and the measured field strength of both antennas.
When you have clicked on a marker, you can enter a comment in the “Comment” field. A “C” appears in the flag of the marker. The comment is displayed again when you click on the marker (see Marking measured values and commenting on them).
