Rack mount for Agilent 66001A MPS keyboard

Description

The Agilent 66lxxA Series Power Modules are used in the Agilent 66000 Modular Power System (MPS) mainframe to provide a range of dc output voltages and currents. The modules are installed or removed from the front of the mainframe without the need for disconnecting any wires. Modules may be connected in series or parallel to provide increased output voltages or currents. The modules can be equipped with optional isolation and polarity reversal relays that are built into the module output connector.

The power module front panel has digital readouts of output voltage and current. It also has annunciators that indicate:

∙constant voltage, constant current, or unregulated operation

∙activation of a protection circuit

∙disabling of the output

∙remote operation (addressed by the controller)

Programming

The power module is programmed over the GPIB from a controller using SCPI (Standard Commands for Programmable Instruments). This makes power module programs compatible with those of all other instruments controlled with this language. Among the functions that can be programmed are output voltage and current, OVP (overvoltage protection), OCP (overcurrent protection), status registers, output relays, and output voltage and current calibration.

In addition, the power module has programmable trigger, list, and RI/DFI (remote inhibit/discrete fault indicator) subsystems. Triggers can occur from signals at the mainframe TRIG IN jack or from selected internal events. The list subsystem generates preprogrammed sequential outputs in response to triggers. The RI/DFI subsystem generates an output on the mainframe FLT line in response to selected internal events or turns off the output in response to an input on the mainframe INH line.

The power module also can be programmed locally from the optional Agilent 66001A MPS Keyboard. The keyboard has an alphabetical command menu for all power module SCPI commands. By scrolling through the menu and entering the appropriate parameters, commands may be created for development or debugging.

Output Characteristic

The power module can operate in either CV (constant voltage) or CC (constant current) mode over its voltage and current output range (see Table 1-1). The operating locus (see Output Characteristic Curve in Table 1-2) shows a single-range, limited two-quadrant capability. The operating point is determined by the voltage setting (VS), the current setting (IS) and the load impedance (Rl). Two operating points are shown. Point 1 is defined by the load line cutting the operating locus in the CV region, which defines the CV mode (curve A). In this mode, the power module will maintain the voltage at VS for varying load currents (determined by V÷Rl) up to IS. If the load demands a current greater than IS, the power module switches to CC mode. CC mode (curve B) is defined by the load line cutting the operating locus in the CC region (see Point 2). Under this condition, the power module maintains the current at IS at some voltage determined by IS x Rl.
