The Rohde & Schwarz SMA100A Signal Generator is a 9 kHz to 3 GHz / 6 GHz signal analysis instrument that achieves unparalleled signal quality, speed and flexibility. Rohde & Schwarz SMA100A signal generators generate CW signals as well as all common types of analog modulation (AM, FM, φM, pulse modulation). In addition, a low‑jitter clock synthesizer option supplies differential clock signals of up to 1.5 GHz independent of the RF frequency. This makes the R&S®SMA100A suitable for a variety of applications, from use in phase noise test systems to tests on mixed‑signal ICs.
Features
- Very low SSB phase noise of typ. -139.5 dBc (at 1 GHz, 20 kHz offset, 1 Hz measurement bandwidth) with option
- Frequency range of 9 kHz to 3 GHz (R&S®SMA‑B103 or R&S®SMA‑B103L) or 6 GHz (R&S®SMA-B106 or R&S®SMA‑B106L)
- Frequency, level and LF sweeps
- Phase-continuous frequency setting
- AM, broadband FM/φM (R&S®SMA-B20 or R&S®SMA-B22), pulse modulation
- Built-in LF generator up to 1 MHz, optional multifunction generator (R&S®SMA-K24) up to 10 MHz
- Optional low-jitter clock synthesizer up to 1.5 GHz (R&S®SMA-B29)
- Power measurement using R&S®NRP-Zxx power sensors
- Optional power analysis (R&S®SMA-K28) using R&S®NRP-Zxx power sensors for scalar network analysis or automatic pulse parameter measurement
