In digital wireless communication systems one or multiple users are assigned to a physical RF channel. With analog systems only one user per carrier is possible. Output spectrum of the transmitter has to be restricted to the assigned channel in order to avoid interference with the neighbor channels. With the switch over to digital modulation formats more user per channel are possible. They share one channel by using only part of the time for transmission (Time Division Multiplex Access, TDMA) or by coding the transmission by orthogonal sequences for distinction to other users (Code Division Multiples Access, CDMA). Beneath the restriction of modulation spectrum with TDMA systems also time behavior of the transmitted signal is critical. One reason is that in a multi-user situation only one user is allowed to transmit within his assigned time slots. Another reason is that by switching a carrier on and off spectrum of the transmitter splatters and causes additional interference in other RF channels.

Adjacent Channel Power performance of power amplifiers used in digital TV systems has to be guaranteed over a wide frequency range, 54 to 890 MHz, which may lead to time consuming test procedures. The application software described here provides swept ACP analysis, using AMIQ and SMIQ for signal generation and FSP, FSU or FSE for signal analysis. ACP measurement is performed according to FCC Regulation 47CFR 73.622(h).

Power amplifiers in digital TDMA mobile phones are fed with current only during the active slot to save power. Using conventional measuring equipment, the noise figure, an important parameter in power amplifiers, can only be determined with the amplifier in continuous operation. However, continuous operation can lead to amplifier overload and produce distorted results. Now there is a convenient way of determining the noise figure of amplifiers with pulsed power supply: using a Spectrum Analyzer (FSP or FSE or FSIQ or ESI), Noise Measurement Software FS-K3 and a function or pulse generator.
