Hioki 8938
FFT Analog Unit
Product Highlights
- Simply slot the 8938 into the MEMORY HiCORDER for use
- Input Number of channels: 2, Connector: Insulated BNC
- * Input isolated from output, inter-channel isolation
- Measurement ranges 5 mV to 20 V/division, 12 ranges, the measurement resolution is 1/80 of range
- AC voltage for possible measurement/display using the memory function: 280 V rms
- * When attached to recorder where full-scale (f.s.) = 20 divisions
- 10 mV to 50 V/division, 12 ranges, the measurement resolution is 1/160 of range
- AC voltage for possible measurement/display using the memory function: 280 V rms
- * When attached to recorder where full-scale (f.s.) = 10 divisions
- Low-pass filter: 5/500/5 k/100 kHz
- Anti-aliasing filter Cutoff frequency 20/40/80/200/400/800/2 k/4 k/8 k/20 k/40 kHz auto-select (linked to frequency range)
- Maximum sampling rate 1 MS/s (simultaneous sampling of two channels)
- Accuracy DC amplitude: ±0.4 %f.s. Zero-position: ±0.1 %f.s.
- Zero-position -50 % to 150 %, 1 % step * With zero-adjustment function
- Frequency characteristics DC to 400 kHz ±3 dB with AC coupling: 7 Hz to 400 kHz ±3 dB
- Max. allowable input 400 V DC (upper voltage which when applied to between input pins does not damage them)
- Max. rated voltage to earth 370 V AC, DC (upper voltage which when applied to input channel casing or between input channels does not damage them)
