Att
max
Maximum attenuation of the measurement setup before deembedding, with reference
to a frequency response normalized at DC to 0 dB. The deembedding filter must
amplify the amplitude response by the "Att
max
" value, and thus also increases the noise
by this value. The value also helps to decide whether deembedding is useful for the
defined effective bandwidth.

Att
DC
, Gain
DC
Maximum attenuation or gain of the measurement setup before deembedding at DC.
This value is the expected basic attenuation or gain, which is corrected by deembed-
ding.
Remote command:
DEEMbedding<m>:CADC? on page 2302
Gain
max
Maximum gain of the measurement setup before deembedding, with reference to a fre-
quency response normalized at DC to 0 dB. The deembedding filter must attenuate the
amplitude response by this value. The value helps also to avoid an overload of the
ADC.

19.4 Proven probe, proven cable
The R&S RTP can measure probes and cables and determine their S-parameters.
These components are called proven probe or proven cable, and their characteristics
are saved in *.rs2p files. The measurements require hardware option R&S RTP-B7.
For proven probe, also the R&S RT-ZF30 probe test fixture is needed
19.4.1 Characterization of proven probes and cables
To get the S-parameters of proven probes and cable, several measurements are nee-
ded. A wizard guides you through the process, and graphics show how to connect the
setup. You can also save the result of each step and speed up further measurements
by saved step results.
The wizard steps are the following:
● Proven probe / cable setup................................................................................. 1073
● Normalization...................................................................................................... 1074
● Measurement...................................................................................................... 1075
● Response............................................................................................................1076
