AC voltage level measurement

Ensure that the input coupling is set to AC before measuring AC voltage level. Refer to
NOTE
"Input Configuration (Analog Analyzer)" on page 246 and "Measurement Configuration
(Digital Analyzer)" on page 240 for more information.
AC voltage level measurement is the most common measurement function of an AC signal.
The U8903B provides two types of AC level detection consisting of rms and peak-to-peak.
When the rms detection method is selected, the AC voltage measurement is expressed as
an rms value. Likewise, if the peak-to-peak detector is selected, the result is a
peak-to-peak value.
As an example, for a 1 Vrms sine input signal, the display will show 1 V if the rms detector
is selected. On the other hand, if the peak-to-peak detector is selected, the display will
show 2.828 V (1.414 × 2).
AC voltage level measurement function mode is applicable for the analog, digital, and
Bluetooth analyzer. The settings for AC voltage level measurement are displayed as shown
in Figure 4-12, Figure 4-13 and Figure 4-14 for the analog, digital, and Bluetooth analyzer
respectively.
