The Rohde & Schwarz SML03 RF Signal Generator has an AF generator covering frequencies from 0.1 Hz to 1 MHz. Its signal can also be brought out for external applications at a separate connector. For two-tone modulation, you can operate the AF generator together with an external signal source. Option SML-B3 upgrades the R & S SML 03 for pulse modulation. In addition to a high-end pulse modulator, this option includes a pulse generator with enhanced features. All modulation modes are possible simultaneously. Only frequency and phase modulation exclude each other because they share circuitry in SML. You can set frequency with crystal resolution of 0.1 Hz. With option SML-B1 (OCXO reference oscillator) frequency accuracy fulfills even the most exacting requirements. The R&S SML 03 is fitted with an electronic attenuator to standard. Any number of levels may be set without causing wear, and setting times of 5 ms are typical. Using special frequency response correction, level error of <±0.5 dB up to 2 GHz and <±0.9 dB up to 3.3 GHz is obtained. With the R&S SML 03 the RF signal is generated by frequency division, resulting in excellent figures for SSB phase noise. Thanks to their low spurious FM of typically 0.5 Hz (at 1 GHz, 0.3 kHz to 3 kHz weighting bandwidth to CCITT), minimal SSB phase noise and high spurious suppression, these signal generators are ideal for all in-channel measurements on receivers.
