Extended Dynamic Range
Options R&S
ZNB4|8-B52 and R&S
ZNB4|8-B54
Hardware options R&S
ZNB4|8-B52/-B54 are only available for new R&S
ZNB4 or
R&S
ZNB8. They extend the dynamic range up to 140 dB (typically 150 dB) for full 2-
port calibrated measurements. Compared to standard R&S
ZNB4|8 analyzers, the
noise floor of the receivers is shifted 10 dB down by reducing the attenuation in the
frontends. The trace noise for transmission measurements is also improved.
Hence, a R&S
ZNB4|8 with Extended Dynamic Range option is well suited to test pas-
sive devices with high dynamic range. The extended dynamic range can also be used
to measure accurately devices with high attenuation or to measure devices with
medium attenuation using wider IF bandwidths for higher measurement speed. With 10
dB more dynamic range measurement bandwidths can be increased by a factor of 10.
A typical production application that currently uses a sweep with 201 points with 10
