●
Extended Dynamic Range options are not available for R&S ZNBT20|26|40.
●
Extended Dynamic Range and Receiver step attenuators 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.
4.7.23 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 "Step
Attenuators" on page 417. The following step attenuators are available:
