R&S
ProbeMeter
The R&S
ProbeMeter is an integrated voltmeter that measures DC voltages with
higher precision compared to the oscilloscope's DC accuracy. The DC measure-
ment is performed continuously and in parallel to the time domain measurement
of the oscilloscope.
High-precision measurements are achieved through immediate digitization of the
measured DC voltage at the probe tip.
The R&S
ProbeMeter measures the differential and common mode DC voltages
simultaneously, and independently of the MultiMode setting.
When the R&S
ProbeMeter is active, the measured values are displayed on the
oscilloscope. The R&S
ProbeMeter state is part of the probe settings of the chan-
nel to which the probe is connected. For details, refer to the user manual of the
Rohde
&
Schwarz oscilloscope.
Advantages of the R&S
ProbeMeter:
●
Measures DC voltages of different levels, no need to adjust the measurement
range of the oscilloscope.
●
True DC measurement (integration time > 100 ms), not mathematical average
of displayed waveform.
●
High measurement accuracy and low temperature sensitivity.
●
Simple means of setting the oscilloscope's trigger level and vertical scaling if a
waveform is not visible.
●
Independent of oscilloscope settings for offset, position, vertical scale, hori-
zontal scale, and trigger.
●
Independent of probe settings for measurement mode and gain.
●
Unique way to detect unexpected or inadmissible common mode voltages,
e.g. bias points - measurement of common mode DC voltages without recon-
necting the probe.
●
Differential measurement range ±2.5 V + offset compensation setting.
Common mode measurement range ±7 V + common mode offset compensa-
tion setting.
