Features and Functions Clearing 34980A Memory For security reasons, you may want to clear memory in the 34980A. To clear all measurement results from memory, either cycle power to the 34980A or send the command. This will also clear the internal DMM...
Page 23: Scpi Language Conventions
Rules for Using a Channel List Many of the SCPI commands for the 34980A include a channel list parameter which allows you to specify one or more channels. From the remote interface, the channel number has the form (@sccc), where s is the mainframe slot number (1 through 8) and ccc is the channel number.
Page 24 In the following command, since the optional <ch_list> parameter is omitted, the command will be applied to the internal DMM. If the internal DMM is disabled or is not present, an error will be generated. INP:IMP:AUTO ON !Applies to the internal DMM 34980A User’s Guide...
Page 25: General Measurement Configuration
Overview of Measurement Modes Two modes of operation are available with the 34980A, depending on the level of switching and measurement that you wish to directly control: the Stand- Alone DMM Mode and the Scanning Mode.
Page 26 In the Scanning Mode, the 34980A automatically controls a sequence of measurements using the internal DMM, possibly across multiple channels, and stores the results in memory. The 34980A closes and opens the appropriate channel relays and Analog Bus relays required for the sequence.
Page 27 READ? command performs a scan of the channels in the scan list. • If you specify a <ch_list>, regardless of whether a scan list is currently defined, the READ? command performs a “temporary” scan of the specified channels (independent of the present scan list). 34980A User’s Guide...
Page 28: Analog Buses
Analog Buses The 34980A provides four 2- wire internal Analog Buses for easier signal routing. You can route your measurements directly to the internal DMM using the 34980A multiplexer and matrix modules, or you can connect to external signals via the Analog Bus connector located on the instrument’s...
