Rohde & Schwarz has extended the frequency range of its analog microwave signal generator, the SMA100B upto 67 GHz. In over-range operation, it even provides signals up to 72 GHz. This signal generator generates signals with very low single side-band phase noise and high output power with extremely low harmonics at the same time.
With the new frequency options, the SMA100B now covers frequency ranges of up to 31.8 GHz, 40 GHz, 50 GHz and 67 GHz. The analog microwave signal generator supports all relevant application fields in the aerospace & defense, wireless communications and semiconductor industries. It is a future proof investment for all microwave applications and an ideal instrument for the characterization of microwave components, devices and systems.
The 40 GHz instrument covers all major radar bands, and with the 67 GHz instrument engineers have a signal source that covers the emerging Q/V band used for very high throughput satellite feeder links. With the introduction of the 5G mobile network standard, first commercial deployments will use frequencies up to 39 GHz or even higher, while the use of frequencies beyond 40 GHz is under investigation. The 67 GHz instrument supports component testing in the 60 GHz frequency range also for non-cellular standards such as IEEE 802.11ad and in over-range operation for standards such as IEEE 802.11ay.
Purest Signals for First Class Devices
Thanks to its ultra low phase noise option, the R&S SMA100B can output the purest RF signals with a single sideband phase noise of -120 dBc/Hz (40 GHz, 20 kHz offset; measured). It can act as an ideal local oscillator (LO) during radar system integration or in radar test systems. With the increase in sample rates of analog to digital converters (ADC) and digital to analog converters (DAC), clean RF carriers with lowest phase noise and lowest wideband noise are required. Lowest wideband noise of –150 dBc/Hz (e.g. at 30 GHz, 40 MHz offset; measured) helps to measure the true performance of a device. With this industry-leading instrument, users can ensure their products and devices have a technological lead and a clear competitive advantage.
Highest Output Power with Lowest Harmonics
At microwave frequencies, attenuation from cables and test fixtures is usually a concern. The SMA100B offers different output power stages to compensate for these losses. Users can upgrade their 31.8 GHz, 40 GHz, 50 GHz and 67 GHz instrument to ultra high power performance via a keycode without having to send the instrument back to service. With the ultra high output power option, the instruments provide sufficient output power with extremely low harmonics, eliminating the need for external amplifiers and filters and simplifying setups at the same time. Equipped with the ultra high output power option, a 40 GHz instrument delivers up to 27 dBm at 25 GHz, while a 67 GHz instrument provides up to 23 dBm at 40 GHz and up to 17 dBm at 67 GHz.
High Dynamic Uninterrupted Level Sweep and Scan AM
The R&S SMA100B provides more than 70 dB of uninterrupted RF level sweep without glitches or signal blanks during the level sweep. With an ultra high output power option installed, it is ideal for measuring the gain transfer curve or output saturation point of high power devices such as amplifiers based on GaN technology or traveling wave tube amplifiers (TWTAs) used in modern satellites. When equipped with the Scan AM software option, the R&S SMA100B can simulate amplitude variation coming from scanning radar antennas in order to perform receiver tests with modulation depths of more than 70 dB.
Plug & Play with R&S LegacyPro
The SMA100B is included in the R&S LegacyPro program and can easily replace obsolete signal generators from Rohde & Schwarz and other manufacturers in automated test environments without the need to modify the test software.
The R&S SMA100B signal generator with all new options is available from Rohde & Schwarz.
