Output
Upon power up, the internal relay at the 9.192 GHz output port is in the OFF position
and the RF ON LED is turned off.
To turn the RF output on, press the soft key
RFOFF in the Main Screen. When the RF
is turned on, the signal level at the 9.192 GHz port is 0 dBm with a preset frequency of
9.192631770 GHz. The 9.2 GHz port has a signal with level +2 dBm ± 1 dB. The
7 MHz port has a signal with preset frequency 7.368230 MHz and level -12 dBm ± 1dB.

MAIN
Frequency Control
The carrier frequency of the 9.192GHz output signal is controllable using the LCD touch
screen on the front panel or through the RS-232 Communication Port. The frequency
can range from 9.189631770 GHz to 9.195631770 GHz (±3 MHz with respect to the
preset value) with a resolution of 10
-6
Hz.

FREQ
Amplitude control
The signal amplitude at the 9.192 GHz port is controllable through the RS-232
Communication Port or using the LCD touch screen on the front panel. The amplitude
can range from -10 dBm to +15 dBm with a resolution of 0.1 dB.

AMPL
Signal Modulation
Four types of signal modulation are available to the user. The first one is linear
Frequency Modulation (FM) and allows to sweep the RF carrier frequency between two
values (F1 and F2) chosen by the user.
