"Keep" is intended for power sweeps. If enabled, at sweep end the output power of
the last measurement point is kept. The configured settling delay is applied.
See Figure 6-76 for an illustration.
Note:
●
Compared to "Auto" mode, "Reduce" and "Keep" can result in significantly longer
measurement times - in particular if an extended settling delay is used.
●
The output power is not altered if there is only a single channel with a single driving
port, performing a "Time" or "CW Mode" sweep.
●
In triggered mode, the analyzer always uses the settings of the first measurement
point while waiting for the trigger signal.
Remote command:
SOURce:POWer:SWEepend:MODE
Settling Delay / Reset Delay ← Power Reduction at Sweep End
If Power Mode at Sweep End is set to "Reduce" or "Keep", the "Settling Delay" defines
the time between Restart Sweep request and sweep start. See Figure 6-76 for an illus-
tration.
Use the "Reset Delay" button to adjust the "Settling Delay" to its default value.
Remote command:
SOURce:POWer:SWEepend:SDELay
External Generators > Minimum Settling Delay
Defines the minimum settling delay for external generators. The delay is enforced:
●
whenever settings are applied to a driving generator port, i.e. as a minimum delay
between the setting and the actual measurement
●
irrespective of the sweep type, and whether the generator actually sweeps
Factory default is 180 µs.
Remote command:
SOURce:POWer:GENerator:SDELay
Global AGC (R&S ZNB only!)
Allows you to select between two AGC algorithms:
"Memory AGC"
(factory
default)
Optimized gain control pre-measurement: only if required and for as
few sweep points as possible.
"Point AGC"
Legacy AGC algorithm: gain control pre-measurement at every
sweep point.
Typically significantly slower than "Memory AGC".
Remote command:
SYSTem:AGC:GLOBal:METHod
Recovery Tab
Provides a single function "Boot into Recovery Screen" that allows you reboot the
instrument and launch the "R&S Recovery Environment". From there you can restore
the original system image (including operating system and firmware).
