SCPI command:
[:SOURce]:BBIN:SKEW on page 696
Signal Monitoring
The section "Signal Monitoring" indicates the overload of the A/D - Converter.
Overload
Indicates that the I/Q input is currently overloaded. This indication also appears in the
block diagram close to the I/Q connector of the Baseband Input block.
If overload is indicated either the amplitude of the external signal is too high (full scale of
0.5 V) and must be reduced or the entered "Peak Level" (in dB full scale) value does not
correspond with the real value and must be corrected. It also can be evaluated automat-
ically with button "Auto Level Set".
SCPI command:
[:SOURce]:BBIN:OLOad:STATe on page 694
Overload Hold
Indicates an overload since last reset for evaluating the measurement.
The Overload Hold state can be reset via the "Reset" button next to the LED, or is reset
automatically by starting a new measurement ("Auto Level Set") or by setting new values
(Crest Factor, PEP, Level).
SCPI command:
[:SOURce]:BBIN:OLOad:HOLD:STATe on page 694
Reset
Executes a reset of the Overload Hold State and LED.
SCPI command:
[:SOURce]:BBIN:OLOad:HOLD:STATe on page 694
