Setting the Frequency of the Current Waveform
Application
The frequency for the currently applicable waveform can be set in relation to
a channel ( 6-72). When frequency coupling is
on
setting also applies to the other channel.
Instead of entering a frequency in the case of the
Pulse
waveform, enter the
pulse period in the WAVE PARAM menu ( 6-108).
Setting the
frequency
1.
In the
menu
press the
function key
.
The entry field for the frequency is displayed together with the current
setting. The default is "1 kHz".
2.
Enter a new value ( 5-55).
The permissible entry range for the frequency depends on the current
waveform:

Note
The
Noise
waveform is a sequence of 262144 random numbers stored in the
waveform memory. When the signal is being generated it therefore exhibits a
periodicity which is dependent on the signal frequency setting. The repetition
frequency is at its lowest when the signal frequency is 381.46973 Hz .
If the noise signal is also frequency-modulated with the aid of a noise signal,
a suitable choice of parameter can reduce the periodicity to < 3 mHz.
