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.

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.

SYNC Noise: AM modulation present on the FM carrier, this reading is wideband.

Total, Pilot, 38 kHz, L, R, L+R, L-R: All readings are referenced to 0dB = 100% modulation or 75 kHz deviation.

Sep, XTalk: Separation and Crosstalk readings are the difference between the flat Left and Right, or L+R and L-R readings.

SCREEN SELECTABLE DATA

None

6. STEREO BARGRAPH SCREEN

38 kHz dB:38 kHz Subcarrier dB bar graph displays the dB RMS value as measured thru the 38 kHz subcarrier suppression BPF.

All readings are referenced to 100% or 0.0dB at 75 kHz deviation.

SCREEN SELECTABLE DATA

None

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. The measurement

assumes the larger signal is the wanted channel verse the lesser unwanted channel and represents the stereo separation.

SCREEN SELECTABLE DATA

None

10. CROSSTALK BARGRAPH SCREEN

SCREEN DISPLAY DATA

L+R & L-R Modulation: Peak Modulation bar graph displays Peak (Red), Average (Yellow), and Min (Green) modulation data.

L+R & L-R dB: dB bar graph displays Flat (Yellow) and De-Emphasized (Green) dB RMS data.

Crosstalk dB:Crosstalk dB bar graph displays the dB RMS value of the difference between the L+R and L-R Flat dB values. This measurement

assumes the larger signal is the wanted channel verse the lesser unwanted channel and represents the stereo crosstalk.
