Common Lead
The meter lead attached to the reference voltage in a measure-
ment application. Because of the isolated channels, the meter
common lead and the scope reference leads do not have to be
connected to the same reference voltage.
Continuity
A test to verify electrical conductivity from one point to another.
Cursors
Paired markers that you can use to make measurements between
two waveform locations. The oscilloscope displays the values
(expressed in volts or time) of the position of the active cursor
and the distance between the two cursors.
DC Coupling
A mode that passes both AC and DC signal components to the
circuit. Available for both the trigger system and the vertical
system.
Digital Real Time Digitizing
A digitizing technique that samples the input signal with a
sample frequency of four to five times the oscilloscope
bandwidth. Combined with (sinx)/x interpolation, all frequency
components of the input up to the bandwidth are accurately
displayed.
Digitizing
The process of converting a continuous analog signal such as a
waveform to a set of discrete numbers representing the
amplitude of the signal at specific points in time.
