[:SENSe][:FIMPedance]:RANGe[:UPPer]?
Description
Sets the measurement range.
With the measurement frequency and the measurement range set to 1 MHz and 47E-12
(47p) or less, respectively, changing the measurement frequency to 1 kHz will
automatically set the measurement range to 100E-12 (100p). On the other hand, with the
measurement frequency and the measurement range set to 1 kHz and 2.2E-9 (2.2n) or
more, respectively, changing the measurement frequency to 1 MHz will automatically set
the measurement range to 1E-9 (1n).
When you set the measurement range with this command, the measurement range mode is
automatically set to the hold range (specified to OFF with the
:RANG:AUTO
command).
Parameters
If one of the settable values is not specified for the parameter, a suitable measurement
range whose recommended range includes the specified parameter (for example, 4.7E-9 if
the specified parameter is 5E-9) is set.
MAX or MIN can be used to specify the parameters.
Query response
{1E-12|2.2E-12|4.7E-12|100E-12|220E-12|470E-12|1E-9|2.2E-9|4.7E-9|10E-9|22E-9|47E-
9|100E-9|220E-9|470E-9|1E-6|2.2E-6|4.7E-6|10E-6}<newline><^END>
If the measurement range mode is Auto, the measurement range used in the immediately
preceding measurement is read out as the query response.
