This refers to any measurement under the MEASURE key.
The Operation Status Register continuously monitors the hardware
and firmware status of the analyzer, and is read-only. To query the
register, send the command :STATus:OPERation:CONDition? The
response will be the decimal sum of the bits which are set to 1. For
example, if bit number 9 and bit number 3 are set to 1, the decimal sum
of the 2 bits is 512 plus 8. So the decimal value 520 is returned.
The transition filter specifies which types of bit state changes in the
condition register will set corresponding bits in the event register. The
changes may be positive (from 0 to 1) or negative (from 1 to 0). Send the
Bit Description
0 A 1 in this bit position indicates that the analyzer is
performing a self-calibration.
1,2 Unused. These bits are always set to 0.
3 A 1 in this bit position indicates that a sweep is in
progress.
4
A 1 in this bit position indicates that a measurement
1
is
in progress.
5
A 1 in this bit position indicates that a measurement
1
is
in a “wait for trigger” state.
6,7 Unused. These bits are always set to 0.
8–14 Reserved. These bits are not used by the analyzer, but are
