Error Messages

Text Only HP-IB Errors

Un-numbered (text only) HP-IB error messages are generally

self-explanatory. For example, trying to retrieve a saved register that

does not exist generates the following error message:

HP-IB Error: Register does not exist.

The following list contains a subset of the Test Set’s text only HP-IB

error messages. These messages represent error conditions which may

require explanation in addition to the error message text.

HP-IB Error during Procedure catalog. Check Config.

This error occurs when the Test Set fails to access an external HP-IB

disk drive when trying to obtain a catalog of procedure files. This would

occur when the Select Procedure Location: field on the

SOFTWARE MENU screen is set to Disk and the operator then tries to

select a procedure filename using the Select Procedure FIlename:

field. Ensure that the Mode field on the I/O CONFIGURE screen is set

to Control and that the External Disk Specification field on the

TESTS (External Devices) screen has the correct mass storage volume

specifier for the external disk drive.

HP-IB Query Error. Check instrument state.

This message usually appears when the control program queries a

measurement that is not currently available (on the currently displayed

screen and in the ON state), such as querying the TX Frequency

measurement when TX Freq Error is displayed.

This message may also be immediately followed by the message,

HP-IB Error: -420: Query UNTERMINATED.

HP-IB Error: Not Enough Memory Available for Save.

This message will be generated when the control program tries to save

the current Test Set state into a Save/Recall register using the

REG:SAVE commands, but there is insufficient memory available in

the Test Set. The Test Set’s non-volatile RAM is shared by the following

resources:

•IBASIC programs

• Save/Recall registers

• RAM (internal)
