APPENDIX B STATUS DATA
-------------------------------------------------------------
The Status word returned from the ST query gives you extra
information when you have received a non-zero <acknowledge>
reply.
The Status word is a 16-bit binary word where each bit set
true represents an error event with a decimal value
determined by the bit position. (See the following table.)
When more than one bit is set true in the status word, the
response from the ST query will be the sum of the decimal
values of the individual bits.
Example:
<status> = 34 This equals 32 + 2
2 = Wrong parameter data format
32 = Invalid number of parameters
DECIMAL <acknowledge>
BIT VALUE EVENT DESCRIPTION VALUE
-------------------------------------------------------------
0 1 Illegal command 1
1 2 Wrong parameter data format 1
2 4 Parameter out of range 1 or 2
3 8 Command not valid in present state 1
4 16 Command not implemented 2
5 32 Invalid number of parameters 2
6 64 Wrong number of data bits 2
7 128 Flash ROM not present 2
8 256 Invalid flash software 2
9 512 Conflicting instrument settings 2
10 1024 User Request (URQ) device dependent
11 2048 Flash ROM not programmable 2
12 4096 Wrong programming voltage 2
13 8192 Invalid keystring 1
14 16384 Checksum error 2
15 32768 Next <status> value available
Remarks:
1. A bit in the status word is set when the corresponding
error event occurs.
2. Bits do not affect each other.
3. New error events will ’accumulate’ in the status word.
This means existing bits remain set.
The status word is cleared (all bits reset) as follows:
1. After the response (the status word) from the ST query
has been read.
2. After the RI (Reset Instrument) command.
