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 4.

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.

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)

The following command configures totalizer channel 5 on the Multifunction

module in slot 2 to be reset to "0" after it is read (RRESet means “read

and reset”).
