Response: None
Example: :sens1:func:stat logg,star
Affects All power meters
Command: :SENSe[n]:FUNCtion:STATe?
Syntax: :SENSe[n]:FUNCtion:STATe?
Description: Returns the function mode and the status of the data acquisition function.
Parameters: None
Response: NONE
LOGGING_STABILITY
MINMAX
PROGRESS
COMPLETE
Example: :sens1:func:stat? → LOGGING_STABILITY,COMPLETE
Affects All power meters
Command: :SENSe[n]:POWer:GAIN:AUTO
Syntax: :SENSe[n]:POWer:GAIN:AUTO<wsp><value>
Description: Set the Auto Gain.
Parameters: 0 = Auto Gain Off.
This is the position for best transient response.
1 = Auto Gain On (Default)
This is the Position for best dynamic.
Auto gain only works for averaging times >=10us. For shorter averaging times, the auto gain is always disabled.
The Auto Gain setting works also in the logging and stability modes, where it also increases dynamic or enhances transient
response.
NOTE: For Logging / Stability, set the Autogain to the same value for all channels.
Send the Autogain commands before setting Average Time or configuring Logging/Stability.
NOTE: Details are in the Application Note "Transient Optical Power Measurements
with the N774x-Series Multiport Power Meter"

NOTE: Disable Auto Gain when modulated Signals are to be measured. In Logging Mode Auto Range is always OFF.
