ORDERING MEASUREMENT READINGS
At default, three measurement readings are displayed at
the same time, although you can display up to four
readings. See Chapters 4 and 6 for more information.
When you exceed the number of selected readings, all
readings shift down one and your latest chosen
measurement is placed on top. Notice that the previous
bottom reading is then removed.
MEASURING FUNCTIONS NOT AVAILABLE
FROM THE MEASURE MENU
There are also a few more measurements that you can
only find in the Scope, Meter or EXT.mV modes. These are
listed below.
Chapter 4 describes how to select the Meter and EXT.mV
mode measurements, and Chapter 5 the Scope mode
measurements.
Additional measurements for Meter and EXT.mV modes
Vrms AC (no DC) Measure the RMS (Root Mean
Square) voltage of the input signal in Meter mode. This is
done with AC-coupled input so that the DC signal
component is blocked and the range is optimized for the
AC signal component. The V DC reading is inhibited due to
AC coupling. In some cases this measurement gives one
more digit of resolution over Vrms AC (DC coupled).
dBV AC+DC (decibel Volts) Measure the voltage ratio of
the AC and DC components of a signal with respect to a
reference voltage in Meter mode. This is done with DC-
coupled input.
dBV AC (no DC) (decibel Volts) Measure the voltage
ratio of the AC component of a signal with respect to a
reference voltage in Meter mode. This is done with AC-
coupled input so that the DC signal component is blocked
and the range is optimized for the AC sinal component.
