Basic specifications

Accuracy guaranteed: 1 year
Measurement functions Number of channels: 2, for voltage measurement
Input connectors Isolated BNC connector (input impedance 1MΩ, input capacitance 40pF), Max. rated voltage to earth: 300V 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 5mV to 20V/DIV, 12 ranges, full scale: 20DIV, AC voltage for possible measurement/display using the memory function: 280V rms, low-pass filter: 5Hz/50Hz/500Hz/5kHz/50kHz
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 series)
Highest sampling rate 2MS/s (simultaneous sampling in 2 channels)
Accuracy DC amplitude: ±0.2% of full scale (with filter 5Hz)
Zero position: ±0.1% of full scale (with filter 5Hz, after zero adjustment)
Frequency characteristics DC to 200kHz ±3dB, (with AC coupling: 7Hz to 200kHz ±3dB)
Input coupling DC, GND, AC
Max. allowable input 400V DC (the maximum voltage that can be applied across input pins without damage)
