The messages in the queue are preceded by a number. Negative (-) numbers are used for SCPI
defined messages, and positive (+) numbers are used for Keithley defined messages. Table 2-5
lists the messages.
NOTE: The :SYSTem:ERRor? query command performs the same function as the :STA-
Tus:QUEue? query command (see STATus subsystem).
3.22.5 :LSYNc:STATe <b> :SYSTem:LSYNc:STATe <b> Control line synchronization
Parameters <b> = O or OFF Disable line synchronization
1 or ON Enable line synchronization
Query :STATe? Query line synchronization
Description 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.
With line synchronization disabled, the integration period starts when the reading is triggered.
See paragraph 2.19.7 for details on line synchronization.

Query :KEY? Query last "pressed" key.
Description This command is used to simulate front panel key presses. For example, to select V (volts) you
can send the following command to simulate pressing the V key:
:syst:key 15
The parameter listing provides the key-press code in numeric order. Figure 3-40 also provides
the key-press code.
