The RF section of the transmitter comprises a fre- quency synthesiser which provides 100mW of frequency modulated RF drive to a two stage, wide band output driver followed by a 25W power amplifier. A thermal shut- down feature is provided in the T856 in case operating temperatures exceed acceptable levels. The T857 is a synthesised, microprocessor controlled FM base station exciter designed for single or multichannel operation in the 400 to 520MHz frequency range 1 . With a standard power output of only 1W, the exciter is designed for use with the T858 50W or T859 100W power amplifiers. The RF section of the exciter comprises a frequency syn- thesiser which provides 100mW of frequency modulated RF drive to a two stage, wide band output amplifier. A wide selection of audio characteristics may be obtained from the audio processor. Optional circuit blocks are an audio compressor and a pre-emphasis stage. They can be bypassed or linked to one or both audio inputs, and then back into the remaining audio circuitry in almost any combination. All audio processor options are link selectable. The synthesiser frequency is programmed via the serial communications port. Eight channel select lines are accessible via an optional D-range connector (D-range 2 - T800-03-0000) at the rear of the set. All components except those of the VCO are mounted on a single PCB. This is secured to a die-cast chassis which is divided into compartments to individually shield each sec- tion of circuitry. Access to both sides of the main circuit board is obtained by removing each of the chassis lids. There is provision within the chassis to mount small option PCBs. The front panel controls include line sensitivity, microphone socket and carrier switch. This switch turns on the carrier (unmodulated) as an aid to servicing. The T856 and T857 are both 60mm wide and each occupies a single space in a Tait rack frame, which has the ability to accommodate up to seven standard modules. 1. Although capable of operating over the 400-520MHz frequency range, the T856 and T857 have an 8MHz switching range (see Section 1.2.3 and Section 3.1). C1.8T856/857 General InformationM850-00 31/01/99Copyright TEL 1.2Specifications 1.2.1Introduction The performance figures given are minimum figures, unless otherwise indicated, for equipment tuned with the maximum switching range and operating at standard room temperature (+22°C to +28°C) and standard test voltage (13.8V DC). Where applicable, the test methods used to obtain the following performance figures are those described in the EIA and ETS specifications. However, there are several parame- ters for which performance according to the CEPT specification is given. Refer to Sec- tion 1.2.6 for details of test standards. Details of test methods and the conditions which apply for Type Approval testing in all countries can be obtained from Tait Electronics Ltd.

The Equipment Under Test (EUT) was set up as shown on the following diagram. 2. The modulation response was measured at three audio frequencies, varying the input level. 3. Measurements were made for both positive and negative deviation. MEASUREMENT RESULTS: See the plots on following pages for both 12.5KHz and 25KHz channel spacing.
