*STB?

The *STB (status byte) query returns the current value of the instru- ment’s status byte.

Syntax*STB?

Description The master summary status (MSS) bit 6 indicates whether or not the device has at least one reason for requesting service. When you read the status byte register, the value returned is the total of the bit weights of all of the bits set to one at the time you read the byte. The following table shows each bit in the status byte register and its bit weight. The *STB? query does not affect the contents of the status byte register.
