Operating manual, 02/2005
Setting the
PSK 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
≤
PSK Period
≤
9901 s
in 100 ns steps
The new setting is stored and then displayed in the parameter field if
modulation is switched on ( 6-133).
Setting the Phase Shift
Application
In phase shift keying the phase of the output signal changes abruptly in step
with the digital modulation signal. In this method the carrier signal delivers
one frequency (with a particular phase). You can define the phase shift.
Setting the
phase shift
1.
In the
submenu
press the
function key
.
An entry field containing the currently applicable setting is displayed. The
default setting is "0 deg".
2.
Enter a new value ( 5-55).
The permissible entry range for the phase shift is:
0 deg
≤
PSK Phase
≤
360 deg
in 0.01° steps
The new setting is stored and then displayed in the parameter field if
modulation is switched on ( 6-133).
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".
2.
Use the
rotary knob
[11] to select a setting.
