Text Only HP-IB Error Descriptions
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 TESTS (Main 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 Disk
In order to save the current Test Set state into a Save/Recall register more non-volatile
RAM will have to be made available. This can be done by,
• reducing the size of the IBASIC program
• deleting one or more existing Save/Recall registers
• recovering RAM Disk space
