GENERAL The Keithley Model 246 is a high voltage supply which provides accurate, stable outputs from 0 to 3100 volts dc. Accuracy is ±1% of the dial setting for all outputs. Stability is ±0.01% ±2 millivolts the first hour or in subsequent 8-hour periods, after a 1-hour warm-up. Line regulation is 0.001% plus 2 millivolts for a 10% change in line voltage, and load regulation is 0.002% plus 2 millivolts from no load to full load. FEATURES. a. Three in-line calibrated dials set ...
The DC 505 Universal Counter/Timer has seven measurement functions: frequency counting, finding frequency ratios, period timing, interval timing, width timing, electronic event counting, and manual event counting. The DC 505 has two input channels (A & B), each having bnc inputs and separate triggering level, attenuators, and coupling mode controls. Both input channels have the same 225 MHz capability. Seven-segment light-emitting diode arrays (しED.s) provide a seven-digit visual ...
