For R&S RT-ZCxxB probes, the determined "Zero adjust" value is displayed and can
be saved in the probe head.
See also "Detect AutoZero, Use AutoZero" on page 195.
Remote command:
PROBe<m>:SETup:OFFSet:AZERo on page 1125
Zero adjust
Zero adjust corrects the effect of an offset caused by temperature drift, and compen-
sates for the remanence. The setting is only available if DC coupling is set.
To set the waveform to zero level by the instrument, use "Detect AutoZero". The detec-
ted value is displayed.
Alternatively, you can adjust the value manually until the waveform is set to zero level.
Make sure to demagnetize the probe before zero adjustment.
The value is given in percent of the maximum range, which is internally defined. The
actual setup range depends on the temperature drift, the measured current and other
variables, and it can change over time. If you measure high currents, the probe core
magnetizes, which impairs the measurement results. Therefore, repeat "Detect Auto-
Zero" before the measurement.
Remote command:
PROBe<m>:SETup:OFFSet:ZADJust on page 1140
Save to probe
Saves the "Zero adjust" value in the probe box. If you connect the probe to another
channel or to another R&S RTx oscilloscope, the value is read out again, and you can
use the probe without further adjustment.
Remote command:
PROBe<m>:SETup:OFFSet:STPRobe on page 1140
5.5.8 Setup for unknown probes
If the R&S RTE cannot detect the probe, and the probe is not a predefined one, you
can set the probe parameters manually.
The following shared probe settings are available:
●
"Type, Name, Bandwidth" on page 195
●
"Detect AutoZero, Use AutoZero" on page 195
●
"External attenuation: Scale, Attenuation" on page 196
