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.
Features
Frequency Agile RF input
AM & Sync AM Noise measurements
HD RF carrier rejections filters to improve analog readings in the presence of HD carriers.
FM Demodulation with 100dB 75 µsec SNR
Variable Bandwidth Composite Filtering
Stereo Demodulation with 100dB L/R Separations
Full metering of Analog Peak and RMS values
RDS Injection/Phase and Full Data decoding
Two SCA Decoders
RF, Composite, and Audio FFT Spectrum Analysis
RJ-45 Ethernet Interface with remote PC software

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. When finished, click again to return to the cursor for that
screen, to exit the screen select the icon and click it. The encoder now returns to changing
screens.
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.
The headphone jack is assignable to any available audio source. To assign the left and right
channels see the Outputs popup menu under Settings.

4. MAIN TUNING SCREEN
SCREEN DISPLAY DATA
Total Peak Indicator: Total Peak Modulation
Pilot Presence Indicator: Pilot Tone Presence
RDS Presence Indicator: RDS Carrier Presence
RDS Sync Indicator: Indicates the RDS decoder has synced to the RDS data stream as is decoding data
SCA#1 Presence Indicator: SCA#1 Carrier Presence
SCA#1 Peak Indicator: SCA#1 Peak Modulation
SCA#2 Presence Indicator: SCA#2 Carrier Presence
SCA#2 Peak Indicator: SCA#2 Peak Modulation
Total, Left, Right, L+R, L-R: Peak Modulation Data
Pilot Injection, Pilot Modulation: Pilot Injection Level, Pilot Modulation represents the AM modulation present on Pilot. This is an indication of off-
the-air reception quality or multi-path.
RDS Injection: RDS Injection Level
SCA#1 Injection, SCA#1 Peak, SCA#2 Injection, SCA#2 Peak: SCA Injection Level, SCA Peak Modulation is normalized to 100% to a selectable
1.0-7.0 kHz deviation.
RF Level: Indicates signal strength in dB for Antenna input, or percent of full scale input level for High Level inputs. To adjust the RF input level, use
the RF attenuator to bring the signal into the green region for proper operation. For both High Level and Antenna Inputs the RF Level indicates yellow
for low signal level values, green for normal levels, and red for overload levels.
SCREEN SELECTABLE DATA
To select a parameter click on the screen, then use the cursor to select the parameter 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 (in the upper right corner of the screen) and push the rotary encoder dial to exit the screen command mode
and return to the screen selection mode.
Tuning Frequency: Selects the Tuning frequency of the FMCS-1 in 100 kHz steps. The unit tunes to the new frequency as the frequency is changed.
RF Attenuator: Adjusts RF input attenuator in 0.5dB steps from 0.0 to −31.5dB of attenuation. There are separate attenuators from the High Level and
Antenna Inputs.

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.
