Model 4861A is a compact, IEEE-488.2/GPIB-to-Analog Interface that provides signals for controlling analog devices from the GPIB bus. The Model 4861A has four floating analog output channels, four differential analog inputs, digital output drivers and digital inputs. The analog values can be scaled to match the physical values of the input signals or of the controlled parameters. The scale factors and all other user set configuration parameters are saved in flash memory until changed. The 4861A accepts both industry standard SCPI commands and easy-to-use short form commands. Typical 4861A applications are controlling power supplies, providing analog stimuli or measuring analog signals.

OEM board versions of the 4861A are available in a variety of configurations to match the analog control needs. The 4861A's firmware can be customized to add new commands or operate with an alternate language such as the MATE CIIL command set.

4861A board vesions are available for OEM applications. Board versions are designed to be mounted in the host's
chassis and are powered from the host's power supply. On OEM boards, the GPIB, LED and Serial headers are
mounted vertically for quick cable connections and to minimize the board footprint.

GPIB Capabilities
IEEE 488 Bus Interface

IEEE 488 Bus interface meets IEEE STD 488.1-1987 and has the following capabilities:
SH1, AH1, T6, L4, SR1, PP0, DC1, RL1, DT1, C0 and E1/E2 drivers.
Bus drivers incorporate power-up/ down protection to prevent sending invalid data to the bus.

GPIB Address Capability 0-30
SRQ Generation SRQs are generated if the event and summary bits are enabled and the event or signal change occurs. Events include the 488.2 Event Status Bits and the monitored digital inputs.
488.2 Common Commands *CLS, *ESE, *ESE?, *ESR?, *IDN?, *OPC, *OPC?, *PSC, *PSC? *RCL, *RST, *SAV, *SRE, *SRE?, *TRG, *TST, and *WAI.
