Introduction Model 2090 Multi-Device Controller

COMPATIBILITY

• Compatible with the a variety of commercial software

including the following:

 Hewlett Packard Commercial Radiated EMI

Measurement Software (HP Part # 85876A).

 Rohde & Schwarz ES-K1 Emissions Software

 Quantum Change Tile software

• Backward compatible with previous ETS-Lindgren

Models 1050, 1060 and 1090 Controller GPIB

command sets (See Appendix A for settings).

• Compatible with the ETS-Lindgren Model 2190 Virtual

Controller GPIB command set and VCS interface.

SEEK/SCAN FUNCTIONS

• SEEK: Allows for movement of device under control to

a target position (valid through GPIB only).

• SCAN: Allows for movement of device under control

cyclically between pre-programmed limits.

TARGET OVERRUN CORRECTION FEATURE

• Constantly monitors inertia induced target overrun. A

special algorithm continually adjusts subsequent

positioning to minimize overrun, allowing for proper

device positioning during tests.

SPECIAL LIMIT SETTING FEATURE

• When used to control a tower, upper and lower limits

can be set independently for both horizontal and

vertical polarizations.

• Prevents element damage at upper or lower limit due to

a change in polarization.
