4.7.3.6 STATus:QUEStionable register

This register contains information on ambiguous device states. They can occur, for example if the
device is operated outside its specification range. It can be queried using the commands
STATus:QUEStionable:CONDition? or STATus:QUEStionable[:EVENt]?.
Table 4-6 Bit allocation of STATus:QUEStionable register
Bit No. Meaning
0 VOLTage
This bit is set if an ambiguous supply voltage occurs. The following voltage test points are to be checked: T-5V,
T+3.3V, T+5VD, T+5VSTDFE, T+5VA, T+25V, T5VINT.
TEMPerature
4
This bit is set if the internal temperature is too high. The test point TEMP in module S1 will be checked.
5 FREQuency
This bit is set if an internal oscillator frequency is ambiguous. The following voltage test points are to be checked:
1ST LO ST, SWP VCO ST, TP 2NDLOPLL, TP_SAM_LEV, TP_VXO_PLL, LDET, TEXREF, TLEVREF
9 LEVel
This level is set when the IF section is overdriven by an excessively high input level. The result of a level
measurement is then suspect.
