Phase modulation (PM)
After selecting DEV (PM MEMU) using the context sensitive keys
, the display shows:
A new value of this deviation can be entered from the data
keypad
or modifi ed by the digital rotary
or one of the
four context sensitive keys
. For more details, refer to the
paragraph ”Setting parameters“.
The deviation range may be set from:
– 0 to 3.14 rad (
<
16 MHz)
– 0 to 10 rad (16 – 1200 MHz)
– Setting with a step of 0.01 rad.
The return to the previous menu is possible by pressing the
PREV. key
and the return to the main display by pressing
the ESC key
.
Example 10:
For PM sine (deviation: 1 rad), the display
shows:
Example 11:
For PM square, the display shows:
CH1—> modulation signal
CH2—> modulated signal (deviation: 1 rad)
FSK modulation
After selecting F0 or F1 (FSK MENU) with the context sensitive
key
, the display shows:
– stp + cur
Fsk1: 522.000000 MHz
– stp + cur
Fsk0: 512.000000 MHz
A new value of Fsk0 or Fsk1 can be entered from the data
keypad
or modifi ed by the digital rotary
or one of the
four context sensitive keys
. For more details, refer to the
paragraph ”Setting parameters“.
The skip frequency Fsk0
Fsk1 or Fsk1
Fsk0 may be set
from:
– 0 to 10 MHz (16 MHz - 1200 MHz)
– step
1
Hz
The return to the previous menu is possible by pressing the
PREV. key
and the return to the main display by pressing
the ESC key
.
Example 12:

sitive key
, the display shows:
– stp + cur
– stp + cur
Psk0: –10.00rad
Psk1: 10.00rad
A new value of Psk0 or Psk1 can be entered from the data
keypad
or modifi ed by the digital rotary
or by one of the
four context sensitive keys
. For more details, refer to the
paragraph ”Setting parameters“.
The skip phase Psk0
Psk1 or Psk1
Psk0 may be set
from:
– -3.14 rad to 3.14rad (
<
16 MHz)
– -10 rad to 10 rad (16 – 1200 MHz)
– step
0.01
rad
The return to the previous menu is possible by pressing the
PREV. key
and the return to the main display by pressing
the ESC key
.
