Description

The Model 1481LA LIN/LOG Ratemeter NIM module offers the user a choice of either linear or logarithmic presentation of the average number of pulses per second being received.

In the linear mode, the Model 1481LA features ten full-scale ranges, from 10 to 500 x 10³counts per second, permitting accurate reading at any range, or the choice of an extremely wide dynamic input range. In this mode, the input pulse rate may be integrated over any one of four switch-selectable time constants, from 0.5 to 40 seconds.

In the logarithmic mode, the Model 1481LA features two three-decade ranges, from 10 to 10⁴counts per second, and from 10² to 10⁵ counts per second, allowing a wide dynamic input range to be monitored without changing the control settings.

The Model 1481LA’s alarm relay is energized whenever the count rate exceeds a pre-selected linear percentage of any full scale range.

The Model 1481LA offers ±0.5% linearity, a rear panel 0-100 mV recorder output, and a 3% precision analog front panel meter.
