Key features of the base module R&S
OSP-B157W8PLUS
In addition to the features of the ".02" version R&S
OSP-B157W8, the ".05" ver-
sion of the module features:
●
Frequency range for signalling up to 7.5
GHz
●
Additional step attenuator R2 for an extended attenuation range, see
Each of the
8 configurable channels
in the R&S
OSP-B157W8 and R&S
OSP-
B157W8PLUS has the following integrated semiconductor components:
●
An individually programmable attenuator
●
An analog power detector for synchronous RMS power measurement with
high sampling rate and burst detection
●
An A/D converter for the power measurement results
●
Solid-state switches, which enable:
– Switching the (vector) signal generator output to the calibration port or to
the DUT ports
– Switching the measurement paths from DUT ports to a spectrum analyzer /
test receiver or to the power measurement
– Signal conditioning via the integrated couplers, directional couplers,
attenuators and combiners
Key features of the frequency extension module R&S
OSP-B157WX
The 40
GHz module R&S
OSP-B157WX is especially designed to provide RF
switching for spurious measurements up to 40
GHz.
