Signal generator achieves optimum output power

Equipped with new options, the RandS SMF100A from Rohde and Schwarz now achieves optimum values in output power and single sideband phase noise.

The RandS SMF100A, which is designed for applications in aerospace and defence and telecommunications, combines measurement accuracy with expanded measurement functionality.

Cable loss, for example, can cause considerable power loss, especially in the microwave range.

To compensate for such loss, the output power of the signal generator must be sufficiently high.

The RandS SMF-B32/RandS SMF-B34 options ensure this by increasing the output power of the RandS SMF100A by up to 8 dB (+23dBm at 20GHz, +14dBm at 40GHz).

With the new options, passive and active components can be tested at very high frequencies without using an external amplifier.

The RandS SMF-B22 option from Rohde and Schwarz also aims to improve the standard for single sideband phase noise.

Users will profit from this when performing tests on multipliers and Doppler radar systems, for example.

The company said that the base unit of the microwave signal generator already features exceptional phase noise performance.

But when equipped with the new option, performance is additionally improved - even for signals very close to the carrier frequency.

For example, at 10GHz carrier frequency and an offset of 10Hz, the improvement is 8dB.
