General Description
Total Harmonic Distortion (Full Linear Load or No Load): 0.25% maximum, 40 to
100 Hz; 0.5% maximum to 500 Hz; and 1% maximum to 1 kHz plus 1%/kHz to 5 kHz.
AC Noise Level: >60 dB RMS below full output (sine wave, 40 to 500 Hz).
Amplitude Stability With Remote Sense: ±0.1% of full scale over 24 hours at
constant line, load and temperature.
Load Regulation: ±0.025% of full scale voltage for a full resistive load to no load;
above 1 kHz, add ±0.015%/kHz.
Line Regulation (DC, or 40 Hz to 5 kHz): ±0.025% of full scale for a ±10% input line
change.
Voltage Accuracy: ±0.1% of range. Above 1 kHz, add 0.2%/kHz. Add ±0.1% of full
scale for "AC PLUS DC" mode. Valid for 5 to 156 VRMS and 10 to 312 VRMS at 25°C
(77°F), sense leads connected. Temperature coefficient less than 50 ppm/°C.
Voltage Resolution: 0.05% of full scale.
Frequency Resolution: 0.01 Hz:
Frequency Accuracy: ±0.01% at 25°C ±0.001%/°C.
Phase Accuracy, Phase-to-Phase Balanced Linear Resistive Load:
±1°, 40 Hz to 1 kHz, plus ±1°/kHz above 1 kHz.
Phase Angle Resolution: 0.1°.
Remote Output Voltage Sense: 5 VRMS total lead drop, maximum.
Output Impedance: 5250 parallel mode, 312V range - meets requirements of
IEC-1000-3-2, Annex A, Supply Source. Valid for equipment classes A, B, C, and D.
