Agilent E1446A

SCPI Driver

The Agilent E1446A Summing Amplifier/DAC can be programmed across the VXIbus backplane (select code 16) from an embedded controller, such as the Agilent E1480A V/360. With this configuration, communication with the register-based amplifier module can be accomplished via four paths:

1.Embedded controller across the VXIbus backplane to the Agilent E1445A AFG (SCPI programming only).

2.Embedded controller to the Agilent E1405/06 Command Module via the GPIB interface (SCPI or register-based).

3.Embedded controller to the Agilent E1405/06 over the GPIB and via the Agilent E1445A (SCPI only).

4.Embedded controller across the VXIbus backplane to the Agilent E1446A (register-based programming only).

Examples of how the amplifier is addressed in paths 1 through 3 are given below. Refer to Appendix C for information on addressing the amplifier during register-based programming.

1.OUTPUT 1680;"INP:IMP 75"

In this addressing configuration, the E1445A must be in the servant area of the embedded controller, and the E1446A must be in the servant area of the E1445A. Select code 16 is the only select code that can be used with this configuration.

2.OUTPUT 70911;"INP:IMP 75"

In this addressing configuration, the E1446 must be in the servant area of the E1405/06. Select code 7 (GPIB) is the only select code that can be used with this configuration.

3.OUTPUT 70910;"INP:IMP 75"

In this configuration, the E1445 must be in the servant area of the E1405/06. The E1446 must be in the servant area of the E1445A. Select code 7 (GPIB) is the only select code that can be used with this configuration.

When using the Agilent E1445A AFG, the SCPI driver is resident in ROM and ready to control the Agilent E1446A. However, to use the Agilent E1405 Command Module, the SCPI driver must be downloaded into the Command Module’s non-volatile memory from a disk. Both DOS and LIF formatted driver disks are shipped with the Agilent E1446A. The drivers can be downloaded from controllers running DOS, BASIC (workstation),
