DEFault
Set units in which flux
density measurements are
returned if FORMat is
ASCii.
T by default.
Note: not all models support
all units. Use UNIT:ALL? to
determine which units are
supported.
:ALL?
Return a list of all the units
supported by this
instrument, followed by the
divisor for each set of units.
The divisor converts the
instrument
’s base units
(µT for the THM1176-
MF/HF/HFC, mG for the
THM1176-LF, and nT for
the TFM1186) to the
associated units.
5-7 PROGRAMMING HINTS
Note that National Instruments' "Measurement & Automation Explorer" (part of the
full NI-VISA package) provides a very useful tool to explore the command set.
Select the THM1176/TFM1186 under "System / Peripherals & Interfaces / USB
Devices," and click the "Open VISA Test Panel" icon. This opens a window from
which you can try all functions available through NI-VISA.
Here are a few notes on how the command set is intended to be used:
-
For simple measurements with the standard settings in single-channel mode,
use the MEASure? command. MEASure:ARRay? returns a time series.
-
Use the UNIT and FORMat commands to change the format in which the
results are returned.
-
Use the READ commands for measurements with non-standard trigger
parameters, or to return raw measurement data without applying calibration
corrections. As with MEASure, READ:ARRay? returns a time series.
-
Use the FETCh command to retrieve all data corresponding to a preceding
MEASure?, READ? or INITiate command, or FETCh:ARRay for the data
