VXi VT1529A/B 사용자 설명서

420 Specifications

The following specifications reflect the performance of the VT1422A with the VT1501A Direct Input Signal Conditioning Plug-on.
The performance of the VT1422A with other SCPs is found in the Specifications section of that SCP’s manual.

Trigger Timer and
Sample Timer Accuracy

100 ppm (0.01%) from -10 °C to +70 °C

External Trigger Input

TTL compatible input. Negative true edge triggered except first trigger will occur if
external trigger input is held low when module is INITiated. Minimum pulse width
100 ns. Since each trigger starts a complete scan of two or more channel
readings, maximum trigger rate depends on module configuration.
