Section 4 Serial Controller

4.78

Enn

The Error Code is

when no error has occurred. If it is non-

zero, then the appropriate error message is appended to the

STATUS

response. For more details about the individual errors, refer to

Appendix B. The Error Code is reset to

when the

STATUS

response is read.

The Triggered (T0) and Cleared (C0) indicators never change.

Since the Analyzer488 is always a system controller, it will never

receive a GET (Group Execute Trigger) or SDC/DCL (Selected

Device Clear/Device Clear) bus command.

STATUS 2

If an ERROR has occurred, issuing

STATUS 2

will cause a two

digit error code to be returned. If no error has occurred, the value

0 is returned. Once the error message is sent by the Analyzer488,

the error condition is cleared. Refer to Appendix B for error

message explanations.

STATUS 3

Returns the state of the Trigger and Record circuitry and the

progress of the recording sequence. A five digit binary number

will be returned with each bit representing the following:

Format : ABCDE

Digit A - Trigger status, 1 = On

Digit B - Trigger Found status, 1 = Trigger pattern found

Digit C - Record status, 1 = On

Digit D - Sequence status, 1 = Sequence complete

Digit E - At End selection, 1 = Step

STATUS 4

Returns

information about the most recent recording sequence. A

two-word description, followed by a numeric value will be

returned for each parameter. Each description and number is a

fixed field string with leading zeros for numeric values. The entire

response is sent as one string.
