7.6 RF Signal Generator
RF Signal Generator Menu
The "RF Signal Generator" transmits an RF signal, many of whose characteristics can be configured.
This menu is accessible via both the "Burst Analysis" menu and the "IQ Spectrum" menu.
RF Gen
Enables the RF Generator to be turned ON or OFF.
RF Gen Lev
Sets the power level of the transmitted signal from the RF IN/OUT connector on the front panel of the
CTS. Note that
RF Gen Lev2 will also be altered when RF Gen Lev is changed due to the connection
between the two RF outputs. The upper and lower limits for RF Gen Lev2 are different in AM mode.
RF Gen Lev2
Sets the power level of the transmitted signal from the RF OUT connector on the rear panel of the CTS.
Note that
RF Gen Lev will also be altered when RF Gen Lev2 is changed due to the connection
between the two RF outputs.
Freq Offset
Adjusts the frequency output away from the centre frequency of the specified channel. This value
cannot be altered when the RF Generator is in the AM mode.
Bit Modulation
Specifies whether the transmitted signal is modulated with a dummy burst (Dum) or whether there is no
modulation (Off) or switches RF Signal Generator to Amplitude Modulation mode (AM) .
Midamble
Specifies the midamble used for the transmitted signal when it is modulated with a dummy burst.
Ramp
Specifies whether the transmitted signal consists of either bursts (ON) or a continuous wave (OFF).
This value cannot be altered when the RF Generator is in the AM mode.
Freq/RF Chan
The transmit frequency can be set either as a channel number or as a frequency. The selection of
which to use can be set up in either the "Config Burst Analysis" or "Config IQ Spectrum" menu. See
section 7.7
for information on the frequency ranges allowed.
Mod. Depth
The Modulation depth parameter is only available for Amplitude Modulation.
