34952A SCPI Programming Examples

The programming examples below provide you with SCPI command examples to use for actions specific to the general purpose switch modules.

The slot and channel addressing scheme used in these examples follow the form sccc where s is the mainframe slot number (1 through 8) and ccc is the channel number. For information on specific configurations, refer to the simplified schematic on page 201.

For complete information on the SCPI commands used to program the 34980A, refer to the Agilent 34980A Programmer’s Reference contained on the 34980A Product Reference CD. For example programs, also refer to the 34980A Product Reference CD.

Digital Input/Output

Example: Configuring a DIO channel The following program segment configures channel 1 on the DAC module in slot 3 as an output and then reads the output value (the channel is not reconfigured as an input). Then, the channel is reconfigured as an input and the value is read again.

The second command below returns 64 as it is physically reading the output data.

SOURce:DIGital:DATA:BYTE 64,(@3001)

SENSe:DIGital:DATA:BIT? 0,(@3001)

The second command below returns whatever is being input externally.

CONFigure:DIGital:STATe INPut,(@3001)

SENSe:DIGital:DATA:BIT? 0,(@3001)

Totalizer

Example: Reading totalizer channel count The following command reads the count on totalizer channel 5 on the Multifunction module in slot 3.

SENSe:TOTalize:DATA? (@3005)

Example: Configuring the totalizer reset mode To configure the totalizer reset mode, send either of the following commands.

The following command configures totalizer channel 5 on the Multifunction module in slot 3 to be read without resetting its count.

SENSe:TOTalize:TYPE READ,(@3005)
