Details
Use this command to lower the audible noise level of the instrument fan.
Quiet fan level speed control may increase internal temperature, which could compromise
performance to specifications.
When you set the fan level to quiet:
•
Audible noise decreases
•
Specifications are only valid for 18 ºC to 25 ºC
•
Additional thermal settling time may be required after changing input connections
Instrument performance can be improved with the use of autocalibration. Allow 90 minutes between
changing fan level and running autocalibration.
Example
:SYSTem:FAN:LEVel QUIET
Set the fan speed to the quiet level. The audible
noise of the fan decreases
