Page 12: Section Ii - Installation
Section II INSTALLATION GENERAL This section of the manual addresses the physical installation of the 541 at its operating location, the ‘nuts and bolts’ of con- necting the unit. This section also references pages where per- tinent setup options and adjustments are discussed. As soon as the equipment is received, inspect carefully for any Unpacking and shipping damage. -
Page 13: Ac Mains Power
The 541 employs an internal ‘universal’ switchmode power AC Mains Power supply that accommodates mains voltages between 88V 264V Certified self-protection circuits have replaced the once-familiar fuseholder. If you need to replace the North-American mains plug with an- other, you will find that the individual cord conductors are col- or-coded in one of two ways. -

normally encountered in speech and music waveforms. Con- sistent discrepancies indicate a possible FM exciter issue. With an appropriate filter selected (Page 19), these modulation readings should not be affected by accompanying HD Radio programs. Great care has been taken in the design of very pre- cise IF filtering to eliminate false indications of FM-overmod at any HD carrier-pair injection ratio. -

reasonable stereo activity. Left and Right meters do not factor-in phase differences between the stereo channels, and phase dif- ferences can play a big part in stereophonic pereception. XTalk (stereo crosstalk) is similar to the Sep (stereo separation) measurement, but in this case it indicates the level difference between the L+R and L-R program audio components. -

The loudness measurement window has a default value of 120 seconds. This may be user-adjusted under Setup / Radio / Loud- ness Window: down to 30 seconds, as may be dictated by the sta- tion’s programming format. This metering method reflects the broadcast implementation of the BS.1770 Standard, and is explained in further detail in EBU Loudness Standard R-128. -
Page 30: Spectrum Plots
SPECTRUM PLOTS The 541 monitor includes an advanced, high-resolution FFT- based spectrum analyzer that delivers detailed and annotated graphic displays of selected signals. Images may be viewed ei- ther through the Webpages utility or from the front-panel LCD- touchscreen. Each signal selected for viewing carries its own family of graph setup options below the display. -

Peak will show the peak value of the signal, and Hold accumulates the highest peak value until the function is deselected. At the bottom, the display Averages: the number of FFT compu- tations selected in the drop-down box. -

HISTORY PLOTS The 541 offers plots of reception and audio parameters viewa- ble over a specified time period, from the past minute to a full, 24-hour time study. Although these data are available through both the Webpages and front-panel LCD-touchscreen displays, Webpage presen- tation provides some extended options covered in this discus- sion that will be found missing with front-panel operation. -

Page 35: Oscilloscope
OSCILLOSCOPE A built-in oscilloscope utility has been included for viewing au- dio and other waveforms through either the Webpages or the LCD-touchscreen displays. Vertical sensitivity is scaled and an- notated with respect to the 100%-modulation point, and the horizontal timebase adjusts for the most meaningful display of the selected signal. -
Page 36: The Bandscanner™ Utility
THE BANDSCANNER™ UTILITY The 541 BandScanner is an annotated RF spectrum analyzer utility that is able to graphically display the entire FM band. From the front panel, BandScanner is found under Graphs. 1) Band-scanning interrupts all mod-monitor functionality dur- Warnings! ing the scan cycle, as it essentially tunes across the band and collects data from each station in the market. -

‘Hovering’ over a yellow-only bar pops up only the Freq: and Bars and Dots RSSI: in a pop-up box. At the completion of an RSSI + RDS scan, a yellow bar with a red dot indicates a station with RDS. Hovering over an RDS station will also present call letters and the PTY (Program TYpe) information as shown in the example. -

The 541 will interface directly with a network controller, tech- nically known as the SNMP ‘Manager.’ The 541 has an embed- ded ASCII text file named Management Information Base, or MIB. In setting up for SNMP operation, the MIB file will have to be downloaded from your unit through the Web interface and uploaded to the SNMP Manager. -
