Simplified Programming Overview
This section gives an overview of the basic techniques used to program
the 34970A over the remote interface. This section is only an overview
and does not give all of the details you will need to write your own
application programs. Refer to the remainder of this chapter and also
the application examples in chapter 7 for more details and examples.
You may also want to refer to the documentation provided with your
programming application for details on outputting command strings and
entering data.
The MEASure? and CONFigure commands provide the most straight-
forward method to program the instrument for scanning. You can select
the measurement function, range, and resolution all in one command.
All other measurement parameters are set to their default values as
shown in the table below.
Measurement Parameter
Integration Time
Input Resistance
AC Filter
Scan List
Scan Interval Source
Scan Count
Channel Delay
MEASure? and CONFigure Setting
1 PLC
10 MΩ (fixed for all DCV ranges)
20 Hz (medium filter)
Redefined when command executed
Immediate
1 Scan Sweep
Automatic Delay
When you configure a channel using MEASure? or CONFigure, it is
important to note that the previous configuration on that channel
is lost. For example, assume that a channel is configured for dc voltage
measurements. When you reconfigure that channel for thermocouple
measurements, the previous range, resolution, and other measurement
attributes are set to their default values.
