2.8 R&S ProbeMeter
The integrated voltmeter can measure DC voltages with high precision compared to
the oscilloscope's DC accuracy. The DC measurement is performed continuously and
in parallel to the time domain measurement of the oscilloscope. High-precision mea-
surements are achieved through immediate digitization of the measured DC voltage at
the probe control box.
The R&S ProbeMeter measures the differential and common mode DC voltages simul-
taneously and without reconnecting the probe. For a definition of differential and com-
mon mode input voltages, see Chapter 3, "Characteristics of Differential Probes",
on page 28.
To activate the R&S ProbeMeter:
► "Vertical" menu > "Probe Setup" > "Ch" tab > "ProbeMeter" = 'on'
After the R&S ProbeMeter has been activated, the measured values are displayed on
the screen of the oscilloscope.
Advantages of the R&S ProbeMeter:
●
Enables the check of DC voltages with different levels without having to adjust the
measurement range of the oscilloscope.
●
Provides a simple means of setting the oscilloscope's trigger level and vertical scal-
ing if a waveform is not visible.
●
Offers a unique way to detect unexpected or inadmissible common mode voltages,
e.g. bias points - measurement of common mode DC voltages without reconnect-
ing the probe.
●
Independent of oscilloscope settings for offset, position, vertical scale, horizontal
scale, and trigger.
●
Independent of probe settings for measurement mode and gain
●
True DC measurement (integration time > 100 ms), not mathematical average of
displayed waveform.
●
Measurement range ±maximum allowable voltage +offset compensation setting.
Maximum measurement accuracy is achieved when offset compensation is
switched off.
●
The measurement is independent from the scale of the oscilloscope.
●
High measurement accuracy and low temperature sensitivity.
