RIGOL 2 Command System

*TST?

Syntax
*TST?
Description
Perform a self-test and query the result.
Explanation
The self-test result is denoted by a 32-bit binary number. If the corresponding binary bit is 0, the self-test
item passes the test; while 1 indicates a failure. The return value is the decimal integer corresponding to
the binary number.
The self-test item represented by each bit is as shown below. The bit that is not used is always 0.
bit0: system voltage
bit1: analog voltage
bit2: storage system
bit3: digital core
bit4: digital IO
bit9: fan 1
bit10: fan 2
bit12: inlet temperature
bit13: outlet temperature
bit16: real-time clock
Return Format
The query returns a decimal integer.
Example
*TST? /*The query returns 0 (namely the 32 bits of the binary number are all 0*/
