Enable line synchronization
:STATe?
Query state of line synchronization
This command is used to enable or disable line synchronization. When enabled, the integration
period will not start until the beginning of the next power line cycle. For example, if a reading
is triggered at the positive peak of a power line cycle, the integration period will not start until
that power line cycle is completed. The integration period starts when the positive-going sine
wave crosses zero volts.
With line synchronization disabled, the integration period starts when the reading is triggered.
See paragraph 2.12.7 for details.
IMPORTANT NOTE: The Model 2002 must first be in idle before you can enable line
synchronization.

' Get response from 2002
PRINT #1, "output 16; :init""
' Take 2002 out of idle
