Rohde & Schwarz has enhanced its analog R&S SMB100A mid-range signal generator by adding new frequency options.
The R&S SMB-B120/B120L and R&S SMB-B140/B140L options (L versions
without step attenuator) enable the generator to cover the frequency range from
100 kHz to 20 GHz and 40 GHz, respectively. The R&S SMB100A can now handle everything from analog RF to microwave
applications.
In the new frequency ranges, the R&S SMB100A still offers a very wide dynamic range of -120 dBm to +14 dBm
as standard. New high power options – the R&S SMB-B31 (for the 20 GHz
model) and the R&S SMB-B32 (for the 40 GHz model) – make it possible to
achieve an output power of max. +25 dBm. The new options allow users to skip
the practice of looping in an external amplifier to achieve higher output
power. This technique is now needed only when compensation is required to deal
with attenuation in the test setup. The R&S SMB100A also offers best-in-class spectral purity.
Even at low frequencies, it has very low single
sideband phase noise thanks to an expanded attenuator range and the direct
digital synthesis (DDS) method. These two features make downconversion a thing
of the past. In addition to excellent signal generation performance, the
R&S SMB100A will appeal to space-conscious users with its compact design:
Occupying only two height units and a width of ¾ 19", it needs
considerably less space on the workbench or in the rack than similar products
on the market. Even the fully equipped 40 GHz model weighs only 6.9 kg, making
it suitable for mobile use. The signal generator’s cost of ownership is very
low due to the three-year calibration interval and the low power consumption of
max. 120 W (40 GHz model), which increases the mean time between failure
(MTBF).
The R&S SMB100A from Rohde & Schwarz especially targets users from the
wide-base market and from the aerospace and defense industry. Device and
component manufacturers can use the signal generator for local oscillator
applications and for testing X-band radars, for example. The frequency options
up to 20 GHz (R&S SMB-B120/B120L) and 40 GHz (R&S SMB B140/B140L) and
the high power options (R&S SMB-B31/B32) for the analog R&S SMB100A signal generator are now available from Rohde & Schwarz.
