Glossary Local Oscillator (LO)
Local Oscillator (LO)
An oscillator which produces the internal signal that is mixed with an incoming signal to produce the IF
signal.
Marker
A visually identi fi able point on a waveform trace, used to extract a readout of domain and range values
represented by that point.
Max Hold
Digitally stored display mode which, at each frequency address, compares the incoming signal level to
the stored level and retains the greater level. In this mode, the display indicates the peak level at each
frequency after several successive acquisitions.
MCPR (Multiple Carrier Power Ratio)
The ratio of the signal power in the reference channel or group of channel to the power in adjacent channels.
Min Hold
Digitally stored display mode which, at each frequency address, compares the incoming signal level to
the stored level and retains the lower level. In this mode, the display indicates the minimum level at
each frequency after several successive sweeps.
Modulate
To regulate or vary a characteristic of a signal, typically in order to transmit information.
