NMP-1000

The NMP-1000 is an analog, wide range, linear current mode module with range switching. Ranges may be selected either manually or automatically, locally or remotely. Full scale sensitivities from 1 x 10-11 to 1 x 10-3 A are provided with indication of percent power on a front panel meter, as well as a front panel LED indication of each decade range. For remote operation, a separate panel assembly can be provided with identical range indicating LEDs, display of current and voltage, as well as channel self test functions. Compensation voltage as well as adjustable high voltage power supplies are provided in the module to allow operation with most existing current mode detectors.
