Brief description

When measuring the gain transfer function of an amplifier with internal ALC there are main requirements that an analog signal generator has to fulfill. First, a wide level range must be provided. This is more or less a common requirement met by most signal sources. Secondly – and this is more important – the required level sweep for measuring the gain transfer function must be glitch or blank free.
The R&S®SMA100B together with the option “high dynamic uninterrupted level sweep” (R&S®SMAB-K724) can be ideally used for measuring the gain transfer characteristic of e.g. a TWTA (Traveling-Wave Tube Amplifier). With its glitch free dynamic range of more than 70 dB, it surpasses the 40 dB or more needed for testing TWTAs by far.
