TECHNICAL DETAILS AND OPERATION INSTRUCTIONS FOR ST121
8
Power is changed in % of maximum power.
If "
220V 30-20000kHz
" submenu is selected in main MENU, you will see the submenu which
allows work with signals in 30-20000kHz range outputted through "220V" socket to the power lines. This
allows to fully imitate data transmission channel in 220V lines.
With selection of line "
Modulation OFF
" it is possible to select modulation of carrier signal: FM,
AM or PWM.
If FM is selected "
Frequency
" option will appear allowing selection of modulation signal
frequency. "
Deviation
" option will appear for FM allowing selection of highest deviation for modulated
signal frequency from value of its carrier frequency
If PWM is selected two options will appear: "
Frequency
" allowing selection of frequency of
impulse and "
Ratio
" allowing selection of interval between impulses.
Power is changed in % of maximum power.
If "
IR 940nm
" submenu is selected in main MENU, you will see the submenu which allows work
with IR emitter located on the front panel (Pic. 1 Pos. 7).
With selection of line "
Modulation OFF
" it is possible to select modulation of carrier signal: FM,
AM or PWM.
If AM or FM is selected "
Frequency
" option will appear allowing selection of modulation signal
frequency (for AM and FM modulation). "
Deviation
" option will appear for FM allowing selection of
highest deviation for modulated signal frequency from value of its carrier frequency
If PWM is selected two options will appear: "
Frequency
" allowing selection of frequency of
impulse and "
Ratio
" allowing selection of interval between impulses.
Power is changed in % of maximum power.
Nonlinear element
There are nonlinear elements connected to the contact pairs "1-2" and "7-8" of "RJ-45" socket in
order to imitate nonlinearity in the wireline (Pic. 7).
