QUESTIONABLE STATUS REGISTER
The QUEStionable condition register (see Figure 3-29) contains status bits representing
data/signals which give an indication of the quality of various aspects of the signal.
A bit set in the QUEStionable condition register indicates that the data currently being acquired
or generated is of questionable quality due to some condition affecting the parameter associ-
ated with that bit.
•
0 - Voltage Mode Error — 1 indicates the instrument is in Current mode.
•
1 - Current Mode Error — 1 indicates the Power Supply is in Voltage mode.
•
2 - Not Used — always zero.
•
3 - Thermal Error — 1 indicates a thermal error has been detected.
•
4 - 5 - Not Used — always zero.
•
6 - Slave Error — 1 indicates a slave fault in a master/slave configuration
•
7 - 11 - Not Used — always zero.
•
12 - Voltage Protect Error — 1 indicates a Voltage protection error has been detected.
Front panel display also shows VPROTECT (see PAR. 3.3.3.2 for details).
•
13 - Current Protect Error — 1 indicates a Current protection error has been detected.
Front panel display also shows CPROTECT (see PAR. 3.3.3.2 for details).
NOTE: If External Reference is enabled and a protection error occurs, both Voltage Protect
Error (bit 12) and Current Protect Error (bit 13) are set. Front panel display also shows
PROTECT (see PAR. 3.3.3.2 for details).
•
14 - Sinking — 1 indicates the unit is absorbing energy from the load.
•
15 Not Used — always zero.

SCPI PROGRAM EXAMPLES
Refer to Appendix B, Figures B-1 through B-14 for examples illustrating the use of SCPI com-
mands.
Figure 3-30 is an example of a program using SCPI commands to program the BOP Power
Supply. The program illustrated is for a configuration using an IBM PC or compatible with a
National Instruments GPIB interface card. (It will be necessary to consult the manufacturer’s
data to achieve comparable functions with an interface card from a different manufacturer.) This
program sets output voltage (Voltage mode) or voltage limit (Current mode) to 5V, and current
limit (Voltage mode) or output current (Current mode) to 1A, then reads the measured (actual)
voltage and current, then prints the measurements.
