Radio equipment used in mobile services – Methods of measurement for receivers for A3E or F3E emissions
| Published By | Publication Date | Number of Pages |
| BSI | 2002 | 86 |
This standard refers specifically to mobile radio receivers having audio-frequency bandwidths generally not exceeding 10 kHz for the reception of voice and other types of signals, using:
- angle modulation [frequency modulation (F3E)/phase modulation (G3E)], or
- double-sideband amplitude modulation with full carrier (A3E).
This standard is intended to be used in conjunction with IEC Publication 60489-1. The supplementary terms and definitions and the conditions of measurement set forth in this standard are intended for type tests and may also be used for acceptance tests.
For receivers having audio-frequency band widths generally not exceeding 10 kHz for reception of voice and other types of signal using (a) angle modulation (phase/frequency modulation), or (b) double-side band amplitude modulation with full carrier.
