`
`Optionsl MUX-8 Analog Multiplexer
`The Ana.logic DASM-MUXS is an optional &channel, pro·
`grammable, analog multiplexer for the DASM·AD14. The
`MUX& is programmed by downloading a user-defined
`"channel list" via the SCSI bus. The •channel list" contains
`the desired Older in which to switch the input channels.
`The multiplexer also Includes Individual programmable
`gain amplifiers, PGAs, for each channel and can be or·
`dered with safl'1'le-and-hokl amplifiers for 4 or 8 channels.
