FMCS-1 Monitor 1. GENERAL INFORMATION Description The FMCS-1 provides a complete solution for the Analog portions of the FM signal. The unit combines the features and functions of an RF amplifier, FM demod, stereo demod, RDS decoder, SCA decoder, and FFT spectrum analyzer in one product. Using state of the art DSP techniques all of the FMCS-1 processing takes place in the digital domain, this results in FM analog performance that was previously not possible.
FMCS-1 Monitor 2. FRONT PANEL The FMCS-1 front panel consists of a 640x240 pixel color LCD display, a rotary encoder with push switch and a headphone jack. To change screens rotate the encoder, to select a screen and change any available parameters push on the knob. Once a screen is selected use the cursor to select the parameters on a given screen, to change a parameter select and click on it. Selected parameters change from yellow to green.
FMCS-1 Monitor 3. REAR PANEL High Level RF Inputs ............................................................................................................... 87.5 to 108.0 MHz, 0.5 to 5.0 Vrms, 50Ω, BNC connector Antenna Input ............................................................................................................................. 87.5 to 108.0 MHz, 100µV sensitivity, 75Ω, F connector Analog Composite Outputs ........................................................................

FMCS-1 Monitor 5. DB READINGS SCREEN The dB readings screen contains all the dB RMS readings performed in the FMCS-1, the readings in white are de-emphasized, the yellow readings are flat or wideband. SCREEN DISPLAY DATA RF Level: Depending on which RF Input is selected displays the dB level at the A/D Input, the input begins overloading at +3.0dB. AM Noise: AM modulation present on the FM carrier, this reading is de-emphasized by definition.
FMCS-1 Monitor 7. SCA BARGRAPH SCREEN SCREEN DISPLAY DATA RDS Injection: RDS subcarrier injection as measured thru a 57 kHz BPF. SCA#1 & SCA#2 Injection: SCA Injections are measured thru a user selectable variable bandwidth BPF; see SCA in the popup menus for settings. SCA#1 & SCA#2 Peak: SCA Peak Modulation bar graphs display the Peak (Red), Average (Yellow), and Min (Green) modulation data. All readings a referenced to 100% at a user specified deviation which is adjustable from 1.0 to 7.0 kHz.
FMCS-1 Monitor 9. SEPARATION BARGRAPH SCREEN SCREEN DISPLAY DATA Left & Right Modulation: Peak Modulation bar graph displays Peak (Red), Average (Yellow), and Min (Green) modulation data. Left & Right dB: dB bar graph displays Flat (Yellow) and De-Emphasized (Green) dB RMS data. Separation dB: Separation dB bar graph displays the dB RMS value of the difference between the Left and Right Flat dB values.
FMCS-1 Monitor 11. RF SPECTRUM SCREEN The RF spectrum screen displays the RF spectrum centered around the tuning frequency with frequencies above being positive and below being negative. The amplitude and frequency scales are both adjustable and have cursors associated with them. The RF spectrum is maybe colored such that center green represents the analog carriers, yellow the main HD carriers, and red the extended mode HD carriers.
FMCS-1 Monitor 13. AUDIO SPECTRUM SCREEN The Audio spectrum screen displays the Audio spectrums from 0 to 24 kHz. The amplitude and frequency scales are both adjustable and have cursors associated with them. SCREEN SELECTABLE DATA To select a parameter click on the screen, then select the choice using the knob, and click again. Adjust the parameter using the knob and click to set the new value. To exit this screen, select the screen icon and click on it.
FMCS-1 Monitor 14. RDS BASIC DATA SCREEN The basic RDS data screen displays data encoded on the 57 kHz RDS subcarrier from the RDS decoder.
FMCS-1 Monitor 15. ALARMS/RELAY SCREEN SCREEN SELECTABLE DATA To select a parameter click on the screen, then select the event using the knob, and click again. Use the encoder to select the event parameter and click, set the new value, and click again. To exit the event, select it, and click. The events scroll as the cursor is moved thru the list. To exit this screen, select the screen icon and click on it.
FMCS-1 Monitor 16. POPUP MENUS Many of the FMCS-1 Parameters and Information are accessed using popup menus. To access the popup menus press and hold down the encoder for 2 seconds. To navigate the popup menus rotate the encoder to highlight a menu choice and click the encoder. To exit the pop menu at any time, hold down the encoder for 2 seconds. RF: Settings which affect the RF portion of the signal. Composite: Settings which affect the Composite or baseband part of the signal.
FMCS-1 Monitor 16-2. COMPOSITE POPUP MENU Filter BW: Selects Composite filter bandwidth: Stereo + RDS (passes stereo plus 57 kHz RDS), Stereo + 67 KHz (passes stereo thru 67 kHz SCA, and Stereo + 92 kHz (passes stereo thru 92 kHz SCA), and wideband. To reduce the interference from off-air-noise or HD carriers it is recommended that the Composite filter bandwidth be set as low as possible depending on the SCA’s present. Peak Mod: Adjusts the threshold for the Total peak light on the Main Tuning Screen.
FMCS-1 Monitor 16-4. RF SPECTRUM POPUP MENU Display Mode: The Display Mode affects how the spectrum data is presented, in Realtime mode the spectrum is updated with new data each time, Peak Hold displays the highest value in the last Hold Count value of spectrums, Average displays the average of the last Average Count of spectrums, and Infinite holds the highest values until reset.
FMCS-1 Monitor 16-6. AUDIO SPECTRUM POPUP MENU Input Type: Selects a single or dual input spectrum. Input #1: Input Select #1 determines the input source used for all single spectrums and channel #1 of dual spectrums. Input #2: Input Select #2 determines the input source for channel #2 of dual spectrums.
FMCS-1 Monitor 16-8. OUTPUT SETTINGS POPUP MENU The FMCS-1provides 8 channels of analog audio output, 8 channels of AES/EBU output, and a headphone output. Any one of these output jacks maybe assigned any of the available audio: Mute, L, L(*), R, R(*), L+R, L+R(*), L−R, L−R(*), SCA#1, SCA#2 ,Pilot, Test 0dB, Test −3dB, and Test −6dB. The (*) is the de-emphasized audio, otherwise the audio is flat. The SCA#1 and SCA#2 audio de-emphasis is selected in the SCA pop up window.
FMCS-1 Monitor 16-10. NETWORK CONFIGURE POPUP MENU IP Address: DHCP must be disabled to enter a static IP Subnet: DHCP must be disabled to enter a Subnet Gateway: DHCP must be disabled to enter a Gateway DHCP: Enables or Disables DHCP. If DHCP is enabled the IP, Subnet, and Gateway addresses will be assigned automatically by the DHCP server. To set a static IP address DHCP must be disabled. Apply: To apply network configuration changes click the Apply button.
FMCS-1 Monitor 16-12. INFO SETTINGS POPUP MENU BOOT: Processor Boot Code Version and Date. MAIN: Processor Main Code Version and Date. DSP#1-DSP#6: Digital Signal Processors #1 thru #6 Code Versions and Dates. MICRO: Micro Processor Code Version and Date. UNIT: Unit configuration. SERIAL #: The unit’s serial number.
FMCS-1 Monitor 17. SOFTWARE SETUP AND UNIT UPDATE INFORMATION The FMCS-1 maybe connected to a computer using the BELAR WizWin Software, which can be downloaded from our website at www.belar.com. Connections can be made using the RS-232 port or Ethernet connectors on the rear panel. In addition to accessing the unit remotely, the WizWin Software may also be used to update the FMCS-1 firmware in the field. Please check our website at www.belar.
