16.1.2.2 Using the display during remote control
You can observe the screen while a remote control script is executed. This is helpful for
program test purposes but tends to slow down the measurement. Therefore it is recom-
mended that you switch off the display in real measurement applications where a tested
program script is to be executed repeatedly.
► To switch on the display, tap the "View" button in the upper left corner of the touch
screen.
► To switch off the display, tap the "View" button again.
16.1.2.3 Returning to Manual Operation
The instrument switches back to manual operation when the remote connection is closed.
Besides, you can return to manual operation manually or via remote control.
► To return to manual operation:
● Tap the "Local" button in the upper left corner of the touch screen.
● VXI-11 protocol: Use &GTL interface message.

instrument or polling a parameter value. Queries are formed by directly appending
a question mark to the command header.
