Introduction

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 specification. However, there are several parameters for
which performance according to the CEPT specification is given. Refer to
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 terms "wide bandwidth" and "narrow bandwidth" used in this and following sec-
tions are defined in the following table.
