2 Receiver Specifications This chapter provides specifications pertaining to the receiver module. The performance figures given in these specifications are applicable only to the receiver module operating as an integral part of a TB7100 base station. These performance figures are minimum figures, unless otherwise indicated (e.g. “typical”), for equipment operating at standard room temperature (+22°C to +28°C [+71.6°F to +82.4°F]) and standard test voltage (12 VDC).
Identifying the Receiver You can identify the model and hardware configuration of a receiver module by referring to the product code printed on a label on the top of the module. The meaning of each character in the product code is explained in the table below. Note This explanation of receiver product codes is not intended to suggest that any combination of features is necessarily available in any one Receiver.
