1250 Frequency Response Analyzer Additional Displayed Information
AMK/1250/3 11-13
These five Error Code numbers only appear when page 1 of the µP Status is displayed.
The "Errors and Warnings" field of the Display will show one of the following messages,
but no number.
Message Error Code Number
GEN. STOPPED 30
GEN. O/LOAD 31
AUX. GEN O/L 33
MOD. Ch 1. O/L 34
MOD. Ch 2. O/L 35
11.3.6 GROUP 4. LEARNT PROGRAM, FILE, AND VARIABLE
41 Line number not found, in Learnt Program. This only applies when the Learnt
Program has been compiled using a peripheral device, in which case each line of the
program may be allocated a number. Jump instructions can then be used for program
looping etc., using the line numbers as addresses.
If a command is given to jump to a line number which does not exist in the current
program, ERROR 41 will be displayed.
42 jump outside Program mode: refers to Learnt Program, but only when using a
peripheral device. The 1250 will obey a Jump instruction when it forms part of a
program which is being run from the Memory, but not when it is sent directly from an
external keyboard.
For example, the stored program may contain:
Line 06 JP20 CR, meaning jump from Line 6 to Line 20. This jump will be executed
when running the program from Memory. However, if the program is loaded into
Memory, and the command JP20 is sent from the keyboard to try and start the program
from Line 20, ERROR 42 will be displayed.
43 Attempt to step Variable out of range. Also applies to an attempt to use Variable
on a parameter whose value has not been entered.
44 File empty, will be displayed in response to the [LIST]FILE command or the
[DISPLAY]FILE command if the File is empty. However [CLEAR]FILE may still be
used.
45 Illegal File Access. It is illegal to try to Display, List or Clear the File whilst the
Analyzers are running, or if they have been stopped in mid-measurement (by means of
the Generator Stop key).
46 Illegal File size entry. Attempt to change File size during a measurement; or to
reduce File size without first clearing; or to enter a File size greater than the number of
free Blocks available.
11.3.7 GROUP 5. MISSING BOARDS
An Error Code number in this Group will be displayed only if the 1250 is commanded to
perform an operation requiring a board or boards which are not fitted, e.g. if Modulation
is programmed but no Mod/Demod board is present.
