Functional Elements

The IEEE 488.2 standard requires a list of the functional elements which are used by the GB1400 receiver. These are the functional elements used in constructing the remote commands that control the receiver. For more information, see the IEEE 488.2 standard, sections 4.3, 7.1.1, and 7.3.3. From Tables 4.2 and 4.3 of the IEEE 488.2 standard, the receiver does the following:

< program	message>		< program	message terminator>
< program	message	unit>	<program	message unit separator>
<command message unit>			<query message unit>
< command program		header>*	< query program		header>*
< program	header separator>		< program	data	separator>
< program	data>		< decimal numeric program data>
< character	program	data>	<non-decimal numeric program data>

*<compound command program header> and <compound query program header> are not handled.

Specific Command Implementations

The reset command “*rst” performs a device reset. As defined in the IEEE 488.2, it will:

∙reset the device settings to default settings, with the exception of stored memory locations and any remote interface settings

∙Macros are not implemented in the GB1400, thus macros are ignored

∙force the receiver into Operation Complete Command Idle State (OCIS) and Operation Complete Query Idle State (OQIS)

Self Test Query

This tests the receiver's basic functionality. The scope of the self test function is limited.

Overlapped vs. Sequential Commands

All commands are sequential commands.

Operation Complete Message

All command actions are immediate (no overlapped commands), such that operation complete is immediate.
