To achieve the higher sensitivity, with the Extended Dynamic Range option
–
the compression point (0.1 dB) is reduced
–
the maximum output power is reduced

The Extended Dynamic Range hardware options for the R&S
ZNBT8 have similar RF
properties as the Extended Dynamic Range hardware options for the R&S
ZNB4 and
R&S
ZNB8. See the R&S
ZNBT data sheet for details.
Option R&S
ZNBT8-B504 is only available with a new R&S
ZNBT8. With this option,
ports 1 to 4 are equipped with Extended Dynamic Range reflectometers instead of
standard reflectometers. Options R&S
ZNBT8-B508 to R&S
ZNBT8-B524 are port
extensions with Dynamic Range reflectometers; see
Chapter 5.7.1, "Additional Test
on page 203. They can be retrofitted at Rohde
&
Schwarz
service.

are mutually exclusive
on the same 4-port block.
●
Mixed equipping with Extended Dynamic Range and standard 4-port blocks (with
or without receiver step attenuators) is possible. However, Extended Dynamic
Range can only be guaranteed for Extended Dynamic Range ports.
●
To achieve the higher sensitivity, on Extended Dynamic Range port blocks
–
the compression point (0.1 dB) is reduced
–
the maximum output power is reduced
See the R&S
ZNBT data sheet for details.

Receiver Step Attenuators
Various Options (see tables below)
Receiver step attenuators are used to adjust the received signal levels to the input
level range of the analyzer to avoid damage to the instrument, e.g. if the DUT is a
power amplifier. The attenuation values can be set between 0 dB and 30 dB (in 10 dB
steps); see
on page 387. The following step attenuators are availa-
