SYSTem:ERRor?

Query the instrument’s error queue. A record of up to 10 errors is stored

in the instrument’s error queue. Errors are retrieved in first-in-first-out

(

FIFO) order. The first error returned is the first error that was stored.

When you have read all errors from the queue, the

ERROR annunciator

turns off and the errors are cleared. The error queue is cleared by the

*CLS (clear status) command or when power is cycled. The errors are

also cleared when you read the queue.

See chapter 6 for a complete listing of the HP 34970A error messages.

SYSTem:ALARm?

Read the alarm data from the alarm queue (one alarm event is read and

cleared each time this command is executed). The following is an example

of an alarm stored in the alarm queue (if no alarm data is in the queue,

the command returns “0” for each field).

SYSTem:VERSion?

Query the instrument to determine the present

SCPI version. Returns a

string in the form “

YYYY.V”, where “YYYY” represents the year of the

version, and “

V” represents a version number for that year (e.g., 1994.0).

*TST?

Perform a complete self-test of the instrument. Returns “0” if the

self-test is successful, or “1” if the test fails.
