Remote communications connections
The procedures in this manual use SCPI commands sent to the Model 2461 from a remote interface.
Select one of the remote interface connections shown below. The instrument automatically detects
the connection. For more detailed information about the remote communications connections, see
"Remote communications interfaces" in the
Model 2461 Reference Manual
.
Figure 9: Remote communications interfaces
If you are using the IEEE-488 interface, make sure the primary address of the Model 2461 is the
same as the address specified in the program you will be using to send commands.
Calibration verification and adjustment considerations
When performing the calibration verification or adjustment procedures:
•
Make sure that the test equipment is properly warmed up and connected to the Model 2461 input
and output jacks. Ensure that either the front-panel or rear-panel terminals are selected
(depending on your connections) with the TERMINALS FRONT/REAR button or using the
:ROUTe:TERMinals
<
FRONt
or
REAR
> SCPI command.
•
Make sure the Model 2461 is set to the correct source range.
•
Make sure the Model 2461 output is turned on before making measurements.
•
Make sure the test equipment is set up for the proper function and range.
•
Allow the Model 2461 output signal to settle before making a measurement or adjusting each
point.
•
When using a shunt resistor for current calibration verification and adjustment, make sure the
shunt is properly rated for the current and power being measured. Also, consider temperature
coefficient and other resistance uncertainty contributors in the overall measurement uncertainty
calculation.
•
Do not connect test equipment to the Model 2461 through a scanner, multiplexer, or other
switching equipment.
