- Maximum input charge: ± 500 pC (high sensitivity side 6 range), 50.000 pC (low sensitivity side 6 range)
- Measurement range Voltage input:
- (BNC terminal): 10 mV to 40 V f.s., 12 ranges, DC amplitude accuracy: ± 0.5% f.s.
- Frequency characteristics: DC to 50 kHz -3 dB (when DC-coupled), 1 Hz to 50 kHz -3 dB (when AC-coupled)
- Low pass filter: 5/500/5 kHz, Input coupling: AC/DC/GND
- Max. allowable voltage: 40 V DC
- Measurement resolution: 1/25000 of measurement range (using 16-bit A/D conversion)
- Highest sampling rate: 200 kS/s
- Anti-aliasing filter: Built-in filter for eliminating aliasing phenomenon (aliasing distortion) in FFT operation (Cutoff frequency automatic setting / OFF)
- TEDS: IEEE 1451.1.4 class 1 compatible (Reading sensor information, corresponding to automatic setting of sensitivity)
