4.12 SCPI command subsystems

SCPI commands are categorized into subsystems and are presented in the following alphabetical order:

4.13 Calculate subsystems  Covers the commands for the three Calculate subsystems. :CALCulate1

is used to configure and control the “mX+B” and “PERCENT” math operations. :CALCulate2 is

used to manipulate readings stored in the buffer, and :CALCulate3 is used to configure and control

the limit tests.

4.14 :CALibrate subsystem  Provides a table that summarizes the commands used to calibrate the

Model 2001. Actual calibration procedures are contained in the Model 2001 Calibration Manual.

4.15 :DISPlay subsystem  Explains the commands that are used to control display readings and

messages for the top and bottom portions of the display.

4.16 :FORMat subsystem  Covers the commands used to select the data format for transferring

instrument readings over the bus.

4.17 :OUTPut subsystem  Covers the commands used to select the polarity for the digital output

lines.

4.18 :ROUTe subsystem  Covers the commands that are used to control switching.

4.19 Sense subsystems  Explains the commands of the two Sense subsystems. :SENSe1 is used to

configure and control the measurement functions of the Model 2001. :SENSe2 is used to read the

digital input port.

4.20 :SOURce subsystem  Explains the commands used to control the digital output port.

4.21 :STATus subsystem  Covers the commands used to configure and control the status registers.

4.22 :SYSTem subsystem  Covers miscellaneous commands not covered by the other subsystems.

4.23 :TRACe subsystem  Explains the commands used to control the reading buffer.

4.24 Trigger subsystem  Covers the commands used to configure the Trigger Model.

4.25 :UNIT subsystem  Explains the commands used to select measurement units.
