The independent CW signal is available in all R&S FPL1000 applications if the optional
Internal Generator R&S FPL1-B9 is installed.
For details, see Chapter 7.3.3.1, "Basics on the Internal Generator", on page 283.

Usage
Determines the type of signal provided by the internal generator:
●
"Independent CW source" on page 283: constant frequency and power level
●
"Tracking generator" on page 284: constant power level, frequency follows ana-
lyzer frequency (only available for frequency sweeps in the Spectrum application)
●
"Power sweep" on page 284: constant frequency, linearly increasing power level
(only available in the Spectrum application)
Remote command:
SOURce<si>:FREQuency:COUPling[:STATe] on page 802
SOURce<si>:POWer:MODE on page 805
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 800
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 801
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 801
Frequency
Defines the frequency of the internal generator signal as an 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 800
