INSTALLATION AND OPERATION
The error mode selects when the IEEE-488 rejected entry status is cleared. If turned on.
the error status is cleared when a new message is processed. If turned off, the status is
cleared only when interrogated with the "IR" (interrogate rejected entry) command or
when explicitly cleared with the "CE" (clear error command).
The record mode s
turned on, the message unit is a record. When turned off, the message unit is a command.
The terminator mode selects the character used as the record terminator. The terminator
character is not used for command processing unless the record mode is enabled. When
turned on, the record terminator CR (carriage return) is used. If turned off, the record
terminator
all IEEE-488 messages sent from the Generator.
The unbuffered mode selects when messages from the I EEE-488 interface are processed.
When turned on, messages are read from the IEEE-488 interface only when the
microprocessor is ready to process them. In this mode, the input buffer will contain a
maximum of one message. (A message may be one command or one record, depending on
the setting of the record mode.) When turned off, messages are read from the I EEE-488
interface to the input buffer of the Generator at the fastest rate. In this mode, the input
buffer may contain up to 80 characters.
The valid mode selects when messages are processed by the Generator microprocessor.
When turned on, processing of a new message is begun only after the R F output has
settled and become valid. When turned off, a new message is processed immediately after
the completion of the previous message.
The interface modes can also be programmed using the command, "@" n (where n is an
integer). The interface modes are set to the value of n where n is the sum of the codes for
the desired modes. The integer codes for the interface modes that can be programmed
using the "@'" n commands

For example, t o select the record mode and valid mode, the command is "@" 6.
Interface Mode Example
In this example, the RF output of Generator is connected to a circuit that is being
measured by a voltmeter. The output of the Generator must be settled before the
voltmeter is given it's command to make a measurement.
