SCG 10 - Specifications

Feb 19, 2019

General Specifications

Subcarrier Frequency39 kHz, 41 kHz, 67 kHz, 92 kHz, 110 kHz, 152 kHz, or 185 kHz. Frequency test jack on front panel.
Frequency Stability+/- 0.18%, -10 degrees C to +50 degrees C.
Subcarrier PurityLess than 0.5% THD
ModulationDirect FM
FM DeviationFactory set for +/- 7.5% of subcarrier frequency
Modulator DistortionLess than 1% THD
Audio Processing: Pre-emphasis0, 75, 150, 225 microseconds, user selectable
Audio Processing: Low-pass FiltersAudio cut-off frequencies of 3 kHz, 5 kz or 7.5 kHz, are specified with original equipment order. The lowest possible cut-off frequency is recommended. Maximum cut-off is 12% of subcarrier frequency.
Audio Processing: CompandingAn optional compander decode board is avaialble for installation in the SCG 10 when used in a subcarrier link havig a SCD 10 subcarrier demodulator with a compander decode board. Companding will reduce noise and can mask certain types of main channel to subcarrier cross-talk.
Frequency Response+/-1.5 dB, 25 Hz to 95% of low-pass filter cut-off frequency.
FM NoiseMore than 68 dB below 5 kHz deviation (measured through SCD 10 demodulator directly connected to SCG 10 output, 225 microsecond pre-emphasis, without companding.) With companding -72 dB.
Audio Input Impedance600 ohms balanced (screw terminals or "D" connector pins.)
Muting LevelAdjustable from 0 dB to 40 dB below 100% modulation. (soft mute).
Muted Carrier Level60dB below rated maximum output level
Subcarrier OutputFront panel adjustment, 0.3v to 7.0v P-P input 600 ohms. (BNC).
Remote ControlRemote control by grounding pin 4 of accessory "D" connector
MeteringIlluminated, indcates peak modulation or subcarrier output level.
ControlsMeter Switch, Subcarrier Control Switch, Modulation Level, Automatic Mute Delay, Mute Level, Subcarrier Output Level, Subcarrier Frequency, Subcarrier Frequency Test Jack (located on front panel)
ConnectorsBNC jack for subcarrier output, 9 pin "D" connector for balanced audio input, remote control, FSK input, ground, +18 to 20 volt input, +13.5 volt input, AC receptacle, 6-32 screw terminals for balanced 600 ohm audio input.
RF ProtectionAll input/output circuits filtered for RF. Totally shielded and bonded aluminum enclosure.
Operating Temperature Range-10 degrees C to +50 degrees C.
Power Requirements120/220/240 VAC (voltage to be specified on original order), 50/60 Hz, 10 watts or 12-14 VDC at 50 ma negative ground or 24-28 VDC at 70 ma (28 volt operation require the APS-28/18 power supply)
AC Fuse RatingFor 120 V, use 3/8 amp fuse.
