Description

The standard Power1401 may be expanded in capability by fitting a range of modular top boxes. These expansion boxes make internal connections to the Power1401 motherboard. They require the Power1401 expanded mechanics (can and case) and are unsuitable for end-user installation.

ADC16 : sets of 16 more waveform inputs

The set of waveform input channels may be expanded by adding an ADC16 (4001-3) expansion box with sixteen extra channels, which are mapped onto ADC channels 8-23. Once the Power1401 is told about the extra channels by the installation program, the new ones may be freely used just like the basic set. Software that reads the extra channels will return undefined data values if the waveform expansion box is not installed.

The ADC inputs are of identical design to the ones on the base unit, with an input range of ±5 V (optionally ±10 V). As on the base unit, there is an option of programmable gain ×1, ×2, ×5 and ×10 for 16 waveform inputs (2701PG) or 8 waveform inputs (2701PG8).
