Description These query commands are used to read the contents of the condition registers. Each set of event
registers (except the Standard Event register set) has a condition register. A condition register is
similar to its corresponding event register, except that it is a real-time register that constantly up-
dates to reflect the current operating status of the instrument.
See [:EVENt] for register bit descriptions. Note from the status structure (paragraph 4.6) that the
condition registers precede the transition filters. Thus, only the PTR descriptions apply to the
condition registers.
After sending one of these commands and addressing the Model 2001 to talk, a decimal value
is sent to the computer. The binary equivalent of this decimal value indicates which bits in the
register are set.
For example, if sending :stat:meas:cond? returns a decimal value of 512 (binary
0000001000000000), bit B9 of the Measurement Condition Register is set indicating that the
trace buffer is full.
Programming example 10 OUTPUT 716; “:stat:oper:cond?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Queries the Operation Condition Register.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the decimal value that defines which bits in the register are set.
