2ch, Voltage input, DC to 400kHz band width, built in filter for FFT.
This UNIT is equipped with circuits for two independently usable input channels. 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) |
| Supplied Accessories | None * The input cord is optional |
