8. A void altering parameters under local control when the instrument is also
being controlled over the MP-IB in compatibility mode. It is possible to alter
the parameters in such a way that the instrument no longer behaves like an
IIP 8152A.
Note
When in compatibility mode, altering the units (dBm, dB, Watts)
under local control will not change the units used under remote
control.
9. O n the occurence of a syntax error in compatililty mode, the parser
resynchronizes at the start of the next line. Any commands following
the syntax error on the same line, will be ignored. The HP 8152A
resynchronizes on the next command that it recognizes.
Example Two lines in a program are:
CHi;Ql;CH2;Ui
CH?
The Q1 command will cause a syntax error.
The HP 8152A selects channel A. After the syntax error it
continues with selecting channel B and setting the units
there to Watts. It will respond with 2 to the query.
The HP 8i53A in compatibility mode selects channel A.
After the syntax error the rest of the line is ignored. It will
respond with i to the query.
10. T he setting for the instrument in compatibility mode is not stored in the
battery backed up memory.
