Status Byte Register
The Status Byte Register of the Tester uses the bit 0
Measurement Data Ready Bit
, bit 1
Measuring Status Bit
, bit 4
Message Available
and bit 5
Standard Event Status Summary Bit
as
shown in Figure 4-7 .
Figure 4-7 Status Byte Register
The Status Byte Register contains the following information:
To query the Status Byte Register, send the command
*STB?
.
The response is the decimal sum of the bits which are set to
1
.
For example, if the bit 5 and bit 4 are set to
1
, the decimal sum
of these 2 bits is 48 (32 plus 16) see Figure 4-5 . So the decimal
value 48 is returned.
