DE DANIELSELECTRONICS2-8 Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz2.6 5.0/6.25 kHz Channelization.The operating frequency is determined as follows for Synthesizers having 5.0/6.25 kHz channelincrement capability;• for BCD switch settings (in the range of 0000 to 4999, multiply the switchsetting by 5.0 kHz and add it to the synthesizer base frequency.Example: An OST-3H141 synthesizer has a base frequency of 128 MHz. Theselected channel number is 0988. The synthesizer output frequency is:((988 x 5 kHz) + 128 MHz) = 132.940 MHz• for BCD switch settings in the range of 5000 to 9999, subtract 5000 from theswitch setting, multiplying the result by 6.25 kHz and add it to the synthesizerbase frequency.Example: An OSR-3H162 synthesizer has a base frequency of 150 MHz. Theselected channel number is 7205. The synthesizer output frequency is:((7205-5000) x 6.25 kHz) + 150 MHz) = 163.78125 MHzThe key point to remember is that 5.0 kHz channel increments are selected with BCDchannel switch settings in the range of #0000 through #4999 and 6.25 kHz channelincrements are selected with BCD switch settings in the range of #5000 through #9999.2.7 8.333 kHz Channelization.The operating frequency is determined as follows for Synthesizers having 8.333 kHz channelincrement capability;• Multiply the BCD switch setting by 8.333 kHz and add it to the synthesizerbase frequency.Example: An OST-3A128 synthesizer has a base frequency of 118 MHz. Theselected channel number is 0231. The synthesizer output frequency is:[(1200 x 8.333 kHz) + 118 MHz] = 128.000 MHz |
