Digital Output Commands

SOURce

:DIGital:DATA[:{BYTEWORD}] <data> ,(@<ch_list>):DIGital:DATA[:{BYTEWORD}]? (@<ch_list>)

Output an 8-bit byte or 16-bit word digital pattern to the specified digital output channels. Note that you cannot configure a port for output operations if that port is already configured to be part of the scan list (digital input). You must specify a decimal value (binary data is not accepted). If you are going to write to both ports simultaneously (WORD), you must send the command to port 01. The digital output channels are numbered “s01” (lower byte) and “s02” (upper byte), where s represents the slot number. The :BYTE? (or :WORD?) query returns the last byte or word sent to the specified digital output channel. Returns a number in the form “+255”.

SOURce:DIGital:STATe? (@<ch_list>)

Read the last byte or word sent the specified digital output channels. The digital output channels are numbered “s01” (lower byte) and “s02” (upper byte), where s represents the slot number. This command returns “0” if the channel is an input port or “1” if the channel is an output port.

DAC Output Commands

SOURce

:VOLTage <voltage> ,(@<ch_list>) :VOLTage? (@<ch_list>)

Set the output voltage level on the specified DAC channel. You can set the output voltage to any value between +12 Vdc and -12 Vdc, in

1 mV steps. Each DAC channel is capable of 10 mA maximum output current. The DAC channels are numbered “s04” and “s05”, where s represents the slot number. The :VOLT? query returns the output voltage level on the specified DAC channel. Returns a number in the form “+8.00000000E+00”.
