- Three selectable input ranges: 40 V, 200 V, 1,000 V for optimized resolution
- Simultaneous sampling at up to 800 kS/s per channel (400 kS/s on TMX-E/TMX-R)
- 16-bit resolution with one SAR A/D converter per channel
- 60 kHz bandwidth (-3dB) with 4-pole Bessel anti-aliasing filter
- DC accuracy: ±0.07% of attenuator setting
- Off-ground measurements supported with digital zero suppression
- 4 MΩ minimum input impedance
- Crosstalk better than -80 dB
- Compatible with TMX, TMX-R, and TMX-18 systems
Applications
