For the purposes of this chapter it is assumed that you are familiar with the program-
ming and operation of the controller. Refer to the appropriate manuals for details of the
interface commands.
The requirements of the SCPI standard in terms of command syntax, error handling
and configuration of status registers are explained in detail in the respective sections.
Tables give you a fast overview of the bit assignments in the status registers. The
tables are supplemented by a detailed description of the status registers.
All program examples for IEC/IEEE bus control are written in Visual Basic. A requisite
for Visual Basic programming is that the modules NIGLOBAL (Niglobal.bas) and
VBIB32 (Vbib_32.bas) are added to the projects.
Manual control aims at the greatest possible operating ease. The focus in remote con-
trol is the predictability of device status after a command. Consequently, remote control
programs should always produce a default status to start with (e.g. by the *RST com-
mand) and then make the required settings.
6.2 Brief Instructions
The following short and simple operating sequence allows rapid setup of the instru-
ment on the IEC/IEEE bus and setting of its basic functions. It is assumed that the IEC/
IEEE bus address, factory-set to 20, has not yet been altered.
Interconnect the instrument and the controller by the IEC/IEEE bus cable and power
them on.
Connect generator output channel 1 and analog analyzer channel 1 using a XRL cable.
6.2.1 IEC Bus
Generate and start the following program on the controller:
CALL IBFIND("DEV1", analyzer%) Open channel to device.
CALL IBPAD(analyzer%, 20) Send device address to controller.
CALL IBWRT(analyzer%, "*RST;*CLS") Reset device, analog generator is set dual-channel
to 1 kHz, 0,1 V. Measurement function of analog
analyzer is set dual-channel to RMS measurement.
CALL IBWRT(analyzer%, "INIT:CONT OFF;*WAI") Trigger single measurement result.
CALL IBWRT(analyzer%, "SENS1:DATA1?") Request function measurement result (i.e. result of
RMS measurement) from channel 1.
CALL IBRD (analyzer%, M$) Read in measurement result.
PRINT M$ Output measurement result on-screen.
The screen of the controller displays the RMS function measurement result (volt) of the
generator signal which was measured using the XLR cable.
