CONTrol<Ch>:GPIO<Port>:SHUNt?
Returns the shunt resistance (in Ω) selected by the analyzer firmware for the config-
ured current range (see
).
The dependency between current range and shunt resistance is displayed in the tables
below.
Note:
The high resistance configuration of pins 9 and 10 requires FPGA version 6.1.0
or higher. For older versions of the R&S ZN-B15/Z15 Var. 03, pins 9 and 10 have the
same current range as pins 1 to 8.

Example:
:CONTrol1:GPIO1:RANGe 20mA
:CONTrol1:GPIO1:SHUNt?
Returns 10 [Ω]
:CONTrol1:GPIO1:RANGe 2mA
:CONTrol:GPIO1:TEST:CLOCk:SHUNt?
Returns 100 [Ω]
:CONTrol1:GPIO1:RANGe 200uA
:CONTrol:GPIO1:SHUNt?
Returns 1000 [Ω]
:CONTrol1:GPIO9:RANGe 0
:CONTrol:GPIO9:SHUNt?
Returns 100000000 [Ω]
:CONTrol1:GPIO9:RANGe 100mA
:CONTrol:GPIO9:SHUNt?
Returns 1 [Ω]
