Hioki 8957 HIGH RESOLUTION UNIT

Basic Specifications

• Measurement functions Number of channels: 2, for voltage measurem
• Input connectors Isolated BNC connector (input impedance 1 M?, input capacitance 40 pF), Max. rated voltage to earth: 300 V AC, DC (with input isolated from the unit, the maximum voltage that can be applied between input channel and chassis and between input channels without damage)
• Measurement range 5 mV to 20 V/division, 12 ranges, full scale: 20 divisions, AC voltage for possible measurement/display using the memory function: 280 V rms, low-pass filter: 5/50/500/5k/50k Hz
• Anti-aliasing filter Integrated filter for suppressing aliasing distortion caused by FFT processing (automatic cutoff frequency setting/OFF)
• Measurement resolution 1/1600 of measurement range (using 16-bit A/D conversion; installed in 8860/8861) Highest sampling rate 2 MS/s (simultaneous sampling in 2 channels)
• Accuracy DC amplitude: ±0.2% of full scale (with filter 5 Hz)
• Zero position: ±0.1% of full scale (with filter 5 Hz, after zero adjustment)
• Frequency characteristics DC to 200 kHz ±3 dB, with AC coupling: 7 Hz to 200 kHz ±3 dB
• Input coupling DC, GND, AC
• Max. allowable input 400 V DC (the maximum voltage that can be applied across input pins without damage)
