Data Questionable Power Condition Register
The Data Questionable Power Condition Register continuously monitors the hardware and
firmware status of the signal generator. Condition registers are read only.
Data Questionable Power Transition Filters (negative and positive)
The Data Questionable Power Transition Filters specify which type of bit state changes in the
condition register set corresponding bits in the event register. Changes can be positive (0 to 1)
or negative (1 to 0).
Table 3-8 Data Questionable Power Condition Register Bits
Bit Description
0 Reverse Power Protection Tripped. A 1 in this bit position indicates that the reverse
power protection (RPP) circuit has been tripped. There is no output in this state. Any
conditions that may have caused the problem should be corrected. The RPP circuit can be
reset by sending the remote SCPI command: OUTput:PROTection:CLEar. This bit is always
set to 0.
1 Unleveled. 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 0.
Query: STATus:QUEStionable:POWer:CONDition?
Response: The decimal sum of the bits set to 1
Commands:
STATus:QUEStionable:POWer:NTRansition <value> (negative transition), or
STATus:QUEStionable:POWer:PTRansition <value> (positive transition),
where
<value> is the sum of the decimal values of the bits you want to enable.
