Display blanking
To prevent sensitive data from being displayed, the 2050T Series Signal Generators include a
display blanking facility. This allows various parts of the display to be replaced by a series of
dashes so that values entered by the user or recalled from the memory will not be visible. The
instrument must be unlocked to Level 2 to enable or disable this facility. Consult the Service
Manual for further information.
