Programming the Status Register System
Figure 1-30.
The Data Questionable Power Condition Register continuously monitors output power
status of the instrument. Condition registers are read-only. To query the condition register,
send the command STATus:QUEStionable:POWer:CONDition? The response will be the
decimal sum of the bits which are set to 1.
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 command STATus:QUEStionable:POWer:NTRansition
<num> (negative) or STATus:QUEStionable:POWer:PTRansition <num> (positive) where
<num> is the sum of the decimal values of the bits you want to enable.
Bit Description
0 A 1 in this bit indicates that the reverse power protection circuit has been tripped.
There is no output in this state. Any conditions that may have caused reverse power
should be corrected. After correcting the problem, the RPP circuit can be reset by
sending the remote SCPI command statement :OUTput:PROTection:CLEar or by
pressing the
Reset RPP softkey on the front panel. In 8648 mode, any SCPI command
resets the reverse power protection circuit.
1 A 1 in this bit indicates that the output leveling loop is unable to set the output power.
2
−14 Unused. These bits are always set to 0.
15 Always Zero (0).
