Operating manual, 02/2005
Setting the
FSK period
1.
In the
submenu
press the
function key
.
The entry field containing the currently applicable setting is displayed.
The default setting is "1 s".
2.
Enter a new value ( 5-55).
The permissible entry range is:
500 ns
≤
FSK Period
≤
9901 s
in 10 ns steps
The new setting is stored and then displayed in the parameter field if
modulation is switched on ( 6-129).
Setting the Hopping Frequency
Application
In the case of frequency shift keying, the frequency of the output signal
changes abruptly in step with the digital modulation signal. The carrier signal
delivers one frequency. You can define the second frequency.
Setting the
hopping frequency
1.
In the
submenu
press the
function key
.
An entry field containing the currently applicable setting is displayed. The
default setting is "100 Hz".
2.
Enter a new value ( 5-55).
The permissible entry range for the hopping frequency is:
10 mHz
≤
Hopping Frequency
≤
f
max
in 10 mHz steps
where: f
max
- maximum carrier frequency ( 6-75)
The new setting is stored and then displayed in the parameter field if
modulation is switched on ( 6-129).
Setting the Modulation Signal Polarity
Application
You can use the polarity to choose whether the modulation signal is displayed
as normal (
High
) or inverted (
Low
). In the case of inversion the waveform is
logically inverted.
Setting the
polarity
1.
In the
submenu
press the
function key
.
A selection field containing the specified settings is displayed. The
default setting is "High".
