Amplitude
The Amplitude function is selected by pressing the FUNCTION
AMPL/NOISE key. It provides a measurement of the amplitude of an
analog signal.
Only one channel can be measured at a time. Pressing either the
INPUT A or INPUT B key will select which channel to measure.
Pressing the GEN key after selecting the channel will measure the
gen-mon signal on that channel.
The amplitude can be measured in units of V, dBV, dBu, dBm, dBr,
dBg, or W. The units are selected by the upper left soft key.
The upper right corner of the display shows the measured frequency of
the input signal, or the frequency of the bandpass filter if the
SELECTIVE filter is chosen.
