# SMBB1  Rohde & Schwarz NEW

**Features:**

-   OCXO reference oscillator option
-   For SBM100B
-   Only the SMBB-B1 or SMBB-B1H option can be installed - it is not possible to use both

**Please note:** it is not possible to install both the SMBB-B1 and the SMBB-B1H options. The SMB100B can only accept one.

Even without extra options, the R&S SMB100B delivers outstanding performance. This outstanding performance can be enhanced for a specific application.

For example, the R&S SMBB-B1 option (OCXO) reduces the aging and temperature dependency of the reference frequency and improves single sideband (SSB) phase noise. The R&S SMBB-B1H high performance OCXO option further improves these performance parameters. Compared to the standard instrument, the aging and temperature dependency are improved by more than a power of ten.

##### Very Low SSB Phase Noise

The R&S SMB100B has a very low SSB phase noise of -134 dBc at 1 GHz and an offset of 20 kHz (measured; 1 Hz bandwidth). The R&S SMBB-B1 option (OCXO) and the R&S SMBB-B1H option reduce the close-in phase noise.

Also wideband noise is very low. The R&S SMB100B achieves -153 dB/Hz (typ.) for a 1 GHz carrier at a frequency offset of 30 MHz.

Other benefits of these options include significantly improved long-term stability of the reference frequency and much less temperature dependency.
