Those guidelines are consistent with the safety standard previously set by both U.S. and international standards bodies. The design of this product complies with the FCC guidelines and these international standards. This equipment is intended for use only in a permanent professionally installed licensed site. Licensing of that site may require that an Environmental Assessment be performed based upon human access, antenna type, antenna mounting height, ERP, operating frequency, duty factor, and any co-located transmitters that contribute to the overall Radio Frequency energy exposure level. Compliance is ultimately the responsibility of the site licensee and a determination of compliance can only be made by evaluating the complex factors of the specific site. Product Warranty Information ISC Technologies warrants to the original purchaser that ISC Technologies products are free from defects in material or workmanship for a period of twenty-four months from the original invoice date, subject to the provisions herein. ISC Technologies will repair or replace at its option, FOB our factory, free of charge within one year from…

Operational Description

Radiometrics Midwest Corporation (815) 293-0772 – [email protected] Operational Description FCC ID: SS6ISC-T8411E 1.1 ISC-T8411EGeneral Description The ISC-T8411E is a 100-225 watt transmitter consisting of a DSP exciter assembly and a 225-watt power amplifier assembly. The transmitter may be equipped with an internal isolator option which limits the output power to 200 watts. The transmitter is capable of operating in the range of 138 to 174 MHz. 1.2 ISC-T8411EClock Frequencies All clock signals are contained within the DSP Exciter assembly and are identified as follows: 1. 10 MHz. Reference Oscillator. This signal provides clocking to various logic devices including the digital quadrature modulator ADSP2105 and Modulator DSP ADSP2101. 2. 16.38 MHz. This signal is the clock for the 68HC11 host processor. 3. I20 Option only. 8MHz. clock for a 68HC711 processor. 4. Standard Interface Option Only: 1.25 MHz. clock. 2 EXCITER INTERFACE There are two types of exciter interface boards that allow connections to two different types of transmitter control equipment. The first type is referred to as the I20 interface and allows connection to the GL-C2000 for transmitter controller. The exciter equipped with this type interface is capable of digital modulation only. The second interface type is the Standard Interface, which allows connection to a variety of external control equipment. This interface provides both an analog and a digital modulation path. Emissions: Approval is sought for both 25kHz. and 12.5kHz. channel bandwidths. Emissions designators follow: F3E – analog voice modulation. F1D – data modulation(FSK). F2D – data modulation using a modulated subcarrier (modem tones). 25kHz. Channel bandwidth – emissions designator 16k0F3E F3E – 3kHz. is the highest modulating frequency, 5kHz. is the deviation limit. Bn=2(M) + 2(D) Bn=2(3) + 2(5) Bn=16 25kHz. Channel bandwidth – emissions designator 16k0F2D F2D – 3kHz. is the highest modulating frequency, 5kHz. is the deviation limit. Bn=2(M) + 2(D) Bn=2(3) + 2(5) Bn=16 Radiometrics Midwest Corporation (815) 293-0772 – [email protected] 25kHz. Channel bandwidth – 14k4F1D Highest data rate for two level modulation is 4800bps. 4800 bps represents a highest modulating frequency of 2400Hz. 4.8kHz. is the highest possible digital deviation. Bn=2(2400) + 2(4800) Bn=4800 + 9600 Bn= 14400 Note: 1 symbol=1 dibit= 2 bits. This results in a 4800 bps maximum data rate using 2 level FSK and 9600bps using 4 level FSK. 12.5kHz. Channel bandwidth – 9k6F1D Highest data rate is 4800 symbols per second. This represents a highest modulating frequency of 2400Hz. 2.4kHz. is the highest possible digital deviation. Bn=2(2400) + 2(2400) Bn=4800 + 4800 Bn= 9600 Note: 1 symbol=1 dibit= 2 bits. This results in a 4800 bps maximum data rate using 2 level FSK and 9600bps using 4 level FSK.

Parts List/Tune Up Info

Copyright 2005 ISC Technologies FCC ID: SS6ISC-T8411E The ISC-T8411E power amplifier does not have any field adjustable components. The following procedures can be conducted in the event of module replacement to return the unit to operating condition. VCO-2 Adjustment Procedure Perform the VCO-2 adjustment procedure after installing new VCO/RF amplifier board or after setting new channel carrier frequency. If the transmitter is to operate at more than one frequency, perform the multichannel adjustment procedure. If the transmitter is to operate at only one frequency, perform the single-channel adjustment procedure. Refer to the DSP exciter VDT manual as necessary. 7.3.1 VCO-2 Multichannel Adjustment Procedure 1. Set up VT-100 VDT and select local control (see VDT manual). 2. Select transmitter channel of lowest frequency if not already selected. 3. Use tuning tool supplied to adjust VCO ADJ control through exciter front panel. Adjust for a reading of 2.8 volts (3.5 volts for wideband VCO 263-0082- 062), on VCO2 status display. 4. Return transmitter to service. Procedure is complete. VCO-2 Single-Channel Adjustment Procedure This procedure does not apply to wideband option. 1. Set up VT-100 VDT and select local control (see VDT manual). 2. Select transmitter channel of operating frequency if not already selected. 3. Use tuning tool supplied to adjust VCO ADJ control through exciter front panel. Adjust for reading of 5.0 Vdc on VCO2 status display. 4. Return transmitter to service. Procedure is complete. Forward Power Calibration β€’ Press K to unkey transmitter if transmitter is keyed. β€’ Connect wattmeter and dummy load to transmitter RF output. β€’ Press K on VDT keyboard to key transmitter. β€’ Press and hold U on VDT keyboard until wattmeter reads correct wattage if wattmeter reads below that wattage. β€’ Press and hold D on VDT keyboard until wattmeter reads correct wattage if wattmeter reads above that wattage. β€’ Press Enter on VDT keyboard when the wattmeter reads correct wattage. Copyright 2005 ISC Technologies β€’ Press N on VDT keyboard if wattmeter does not read correct wattage. β€’ Press Y on VDT keyboard if wattmeter does read correct wattage. Caution Wattmeter must read exactly correct wattage to ensure proper metering. β€’ Menu displays TX CALIBRATED. Press K on VDT keyboard to unkey transmitter. β€’ Disconnect wattmeter and dummy load; return transmitter to service. Reflected Power Calibration Disconnect coax cable from output. β€’ Press Enter to calibrate isolator REF PWR. β€’ Isolator reflected power is calibrated. Press enter to proceed. β€’ Reconnect coax cable to output of isolator. β€’ Turn potentiometer R235 fully counterclockwise. β€’ Disconnect coax cable from output of PA. β€’ Press Enter to calibrate PA REF PWR. β€’ Reflected power calibrated, proceed to following steps. β€’ Adjust R235 until VSWR LED on exciter front panel just indicates red. β€’ Turn ac power off then reconnect PA RF output to isolator input. β€’ When ac power is restored, the transmitter will come up in the remote mode. This procedure is finished.
