Clark hess model 5000 phase standard
Clark Hess Model 5000 Phase Standard
For Sale is a Clark Hess Model 5000 Phase Standard. SN/259
These units are in Very good cosmetic & electrical condition.
On one unit the display is a little cloudy but easy to read.
The other two units look unused and in Like NEW condition.
. The world standard for Phase Measurement. Difficult to locate on of these. SPECIFICATIONS PHASE ANGLE Range: 0.000 to 999.999 Resolution: 0.001 from 1Hz to 100kHz OUTPUT FREQUENCY Range: 1Hz to 100kHz Resolution: 1Hz from 1Hz to 6250Hz 10Hz from 6250Hz to 51kHz 20Hz from 51 kHz to 100kHz OUTPUT AMPLITUDE Range: 100mV rms to 100.0V rms Resolution: 2mV from 100mV to 7.1V 25mV from 7.1V to 100V Accuracy: 1Hz to 50kHz: Better than 2.5mV from 100mV to 500mV . Better than 0.5% of setting from 0.5V to 100V 50kHz to 100kHz: Better than 2.5mV from 100mV to 500mV. Better than 1.0% of setting from 0.5V to 100V. Typically better than 0.25% from 0.5V to 100V TOTAL HARMONIC DISTORTION Less than 0.02% (-74dB) from 1Hz to 1000Hz Less than 0.05% (-66dB) from 1000Hz to 20kHz Less than 0.13% (-58dB) from 20kHz to 50kHz Less than 0.32% (-50dB) from 50kHz to 100kHz OUTPUT IMPEDANCE 0.5W plus 1mH for Output Voltages less than 7.1V 0.5W plus 40mH for Output Voltages greater than 7.1V NOISE Less than 0.1mV from dc to 100kHz Less than 0.25mV from 100kHz to 10MHz OUTPUT DC OFFSET Less than 0.5% of the ac output 2mV OUTPUT CURRENT CAPABILITY At least 10mA.
