Common Commands - Keithley 2002 Getting Started Manual

Common commands

Common commands are common to all IEEE-488 devices on the bus. The following infor-
mation summarizes the Common commands that are used most often. For complete details, refer
to Section 3 in the User's Manual.
*CLS
(clear status)
Clears all event registers and Error Queue. After clearing an event register, you can monitor
the register for a bit to set, indicating that an event (such as the buffer becoming full) has oc-
curred.
*SAV <NRf>
(save)
Saves the instrument setup to the specified memory location (0 to 9). The number of available
memory locations depends on the memory option that is installed. With no extended memory,
only location 0 is valid. With MEM1, locations 0 to 4 are valid. With MEM2, locations 0 to 9
are valid. Example: To save the setup to memory location 0, send
*RCL <NRf>
(recall)
Returns the instrument to the instrument setup saved at the specified memory location. Ex-
ample: To recall the setup saved at memory location 0, send
*TRG
(trigger)
When a trigger model control source is set for BUS, event detection is satisfied by sending
this bus trigger. For example, if instrument operation is waiting at the measure (trigger) layer
control source and it is programmed for BUS events,
ing in a device action (measurement).
*WAI
(wait to continue)
This delay is used to allow the
ish before processing any further commands. An
