HP 6038A Service Manual

3-184 The type of error detected can be determined by
sending:
ERR?
and addressing the power supply to talk. The response from
the power supply is in this format:
ERR X
where x is a decimal digit from 0 to 8.
3-185 Table 3-10 lists the error codes with descriptions
of each.
3-186 Test. The power supply runs a series of self tests
when It is turned on. and selected tests can be run for
troubleshooting (see Section V). Either of two subsets of the
self tests can be run by command from the controller. Self tests
can be invoked via the HP-IB by sending the command:
TEST?
3-187 The type of self tests performed depends on whether
the power supply output is turned on or off. See Section V for
a description of each of the self tests.
3-188 If the power supply output is disabled (OUT OFF com¬
mand has been sent), the following tests are performed:
RAM Test #2
ROM Test
Real-Time Clock Test
Serializer Test
PSI Digital I/O Test
PSI DAC/ADC Test
3-189 If the power supply output is enabled (output is on),
only these tests are performed:
RAM Test n
ROM Test
Real-Time Clock Test
Serializer Test
3-190 When the power supply is addressed to talk after
TEST? has been received, it responds in this format:
TEST X
where x is a decimal number from 0 to 22. See Section V for
a listing of test-failure codes. TEST 0 indicates that all tests
passed.
3-191 The test command does not complete until the power
supply control circuits have had time to settle. This prevents
perturbations on the power supply output. The test command
takes about 500 ms to execute.
Table 3-10. Error Codes
Error # Description
0 No Errors
1 Unrecognized Character — A character like ! " # was received.
2
Improper Number — A numeric character {-f —. 0...9) was received but the following characters did not
represent a proper number. For example, + —5 V or .V or + V. Examples of errors that are not error 2 are:
E-1-04 is error 3 because E is not a numeric character and is not used in any command; 12. 34E-01 is error
4 because it is treated as 12 followed by 3.4, and no commands have two numbers separated by spaces.
3
Unrecognized String — A string of consecutive alpha characters that could not be found in the table of
command words was received. Cause could be a spelling error or missing separator. For example, OUTON
would be seen as one word, and would be an error.
4 Syntax Error — A word, number, terminator, or separator was incorrectly placed. For example, ON OUT
UNMASK,CC, or VOUT 5 V lOUT 5A. A syntax error will also result if more than the maximum number
of parameters are specified in the UNMASK mnemonic-form command.
6
Number Out Of Range — A number was received that is too large for the command with which it was
received, for example, VOUT 5£ -f 5, RCL 200, or OLY 100S. Any negative number will also cause error 5.
Note that soft limit errors are error 6.
6
Attempt To Exceed Soft Limits — An attempt was made to program a voltage or current greater than
the soft limit, for example, VMAX10 V; VSET11 V. Note that if the programmed voltage or current is greater
than the maximum rating of the supply, error 5 will result.
7
improper Soft Limit — An attempt was made to program a soft limit less than the associated output value
in either first or second rank. Note that if an attempt is made to program a soft limit greater than the max¬
imum soft limit of the power supply, error 5 will result.
8
Data Requested Without A Query Being Sent — A query command, for example VOUT?, instructs the
power supply to ready data for transmission to the controller. A query command must precede each request
for data by the controller. If the controller requests data from the power supply (with an ENTER or red state¬
ment) without first having sent a query, error 8 will result.
