2 $This Section introduces the T2000 Series II radio, describing models and features availa-ble and their performance.The following topics are covered in this Section:Section Title Page 1.1Introduction 1.2 1.2Specifications 1.31.2.1 1.2.2 1.2.3 1.2.4 1.2.5 1.2.6 1.2.6.1 1.2.6.2IntroductionGeneralReceiver PerformanceTransmitter PerformanceFrequency ReferenceTrunkingT2030, T2035, T2040 & T2050 ModelsT2060 Model1.31.31.51.71.81.91.91.91.3Operating Instructions 1.9 1.4Product Codes 1.108 $ #The T2000 Series II is a high performance mobile two way radio. It covers ten frequency bands between 66 and 870MHz, and is available in both trunked and conventional mod-els.Operation of the T2000 is by handheld microphone, a press-to-talk switch and a range of front panel function keys. The T2020 and T2040 models are fitted with an LCD display and alphanumeric keypad.Most of the functions of the T2000 are microprocessor controlled. The system software is stored in a read only memory (ROM), while the data is stored in a non-volatile memory for ease of programming. Operational parameters can be programmed without opening the radio, via the front panel microphone socket.The T2000 uses a synthesiser with a single VCO switched between transmit and receive.A plug-in TCXO PCB is used to provide a highly stable reference frequency, and dual point modulation gives a flat modulation response at the synthesiser.The standard T2000 RF power output is 25W, except in the T2000-800 which delivers 15W. The receiver is electronically tuned across the entire frequency band and contains an IF noise blanker and RSSI facility. A maximum of 4W of audio is delivered to a 4Ωspeaker.The RF and logic PCBs are shielded from each other in a diecast aluminium chassis, and are connected by two plug-in looms. The T2000 top and bottom covers are also diecast aluminium.There is provision within the radio to mount option PCBs and a 9 or 15 way output con-nector which is used for options requiring connection to external equipment. Standard options include hands-free operation, line control interface, signalling and data trans-mission.The DC supply to the radio must be negative earth and may be between 10.8 and 16V. The T2000 is protected against reversal of the DC supply and is provided with overvolt-age protection.If further information is required about the T2000 or this Manual, it may be obtained from Tait Electronics Ltd or accredited agents. When requesting this information, please quote the equipment product code (e.g. T2010-512-002) and serial number. In the case of the Service Manual, quote the product code (e.g. M2000-00-300), and for circuit dia-grams quote the ‘Title’, ‘Internal Part Number’ (IPN) and ‘Issue’.8 & # #8 8 $ #The performance figures given are typical figures, unless otherwise indicated, for equip-ment operating at standard room temperature.

在电磁灶内部,由整流电路将50/60Hz的交流电压变成直流电压,再经过控制电路将直流电压转换成频率为20-40KHz的高频电压,高速变化的电流流过线圈会产生高速变化的磁场,当磁场内的磁力线通过金属器皿(导磁又导电材料)底部金属体内产生无数的小涡流,使器皿本身自行高速发热,然后再加热器皿内的东西。
1.2 088系列简介088系列是由东芝电子技术开发制造厂设计开发的新一代电磁炉,介面有LED发光二极管显示模式、LED数码显示模式、LCD液晶显示模式、VFD荧光显示模式机种。

When in test mode, connect the antenna socket to a dummy load to prevent interference with trunking systems. Avoid testing on channels in use locally.
When using with LTR or DCS, the deviation meter must have a good low frequency response, to avoid incorrect deviation readings. • Sinad meter or audio distortion analyser, 1kHz notch type (e.g. HP334A, HP339A or Helper Instruments Sinadder). • AC millivoltmeter (e.g. Trio VT-106). • Digital multimeter (e.g. Fluke 75). • 20MHz dual channel oscilloscope and X10 . X1 scope probes (e.g. Trio CS1022). • RF power meter, 50Ω; RF detecting element 50W and 5W for appropriate frequency ranges (e.g. Bird Meter 6154 or 611). • RF power attenuator, 50Ω, total attenuation 30dB (e.g. Weinschel 40-40-33 30dB, 150W). • Microphone test box (refer to Figure 4.1). A multifunction test set may be used as long as it has the appropriate function to perform the calibration correctly e.g. Rhode & Schwarz CMS52 Radio Communications Test Set, with a high stability oscillator.
