Usage
Determines the type of signal provided by the internal generator:
●
"Independent CW source" on page 285: constant frequency and power level
●
"Tracking generator" on page 286: constant power level, frequency follows ana-
lyzer frequency (only available for frequency sweeps in the Spectrum application)
●
"Power sweep" on page 286: constant frequency, linearly increasing power level
(only available in the Spectrum application)
Remote command:
SOURce<si>:FREQuency:COUPling[:STATe]
on page 792
SOURce<si>:POWer:MODE
on page 796
State
Enables or disables the internal generator. The generator signal is output at the GEN
Output
50
Ω
connector on the front panel.
Remote command:
OUTPut<up>[:STATe]
on page 790
Level
Defines the output power of the internal generator.
The default output power is -20 dBm. The range is from -60 dBm to +10 dBm.
Remote command:
SOURce<si>:POWer[:LEVel][:IMMediate][:AMPLitude]
on page 791
Level Offset
Defines an offset to the output power of the internal generator.
Used to adapt the level display, for example to cable loss.
Remote command:
SOURce<si>:POWer[:LEVel][:IMMediate]:OFFSet
on page 791
CW Frequency
Defines the frequency of the independent CW source. The step size depends on the
measurement mode.
If the internal generator is used as a tracking generator, the frequency is coupled to the
frequency of the analyzer. Thus, this setting is not available.
Remote command:
SOURce<si>:INTernal:FREQuency
on page 791
Frequency Offset
Shifts the frequency of the internal generator by the defined offset.
The default frequency of the internal generator is coupled to the (center) frequency of
the analyzer and can be set from 5
kHz to the maximum frequency of the
R&S FPL1000.
Remote command:
SOURce<si>:INTernal:FREQuency:OFFSet
