SYSTem:CARD commands
There is a series of SYSTem:CARD commands that can be used to acquire the following
information about a switching module installed in the Model 2701:
• Return the serial number and firmware revision.
• Determine the maximum allowable voltage.
• Determine if the module supports multiplexer or isolated channels.
• Determine if the module has built-in temperature sensors for internal cold junction,
thermocouple temperature measurements.
• Determine which channels are used for volts/2-wire measurements and which are
used for amps.
• Determine which channels are used for analog or digital output.
