DAC Outputs:
Four BNC connectors provide access to the four individual deglitched 16 bit
digital to analog converter outputs. Digital to analog converter output voltages
/ waveforms, and timings are controlled by the acquisition software. The DAC
channels have an output range of -10.24 to +10.239 volts. These channels are
optically isolated from the computer. All four channels can be used for
simultaneous waveform generation. Use only high quality 75
Ω
BNC cables for
optimal results.

ADC Inputs:
Eight BNC connectors provide access to the eight analog input channels. The
eight analog inputs are divided into two sections of four, labeled “MUX A” and
“MUX B”. Each “MUX” bank is comprised of a single A/D converter
multiplexed into four analog inputs. Each bank has a maximum sampling rate
of 200kHz with a combined aggregate rate of 400kHz. In addition inputs from
each MUX can be simultaneously (co-phased) sampled. Input channel
selection, sampling rate and decimation are specified by the acquisition
software. The ADC channels have an input range of -10.24 to +10.239 volts.
These channels are differential inputs and are optically isolated from the
computer. If the BNC connector shield is left unconnected unexpected results
can occur. Use only high quality 75
Ω
BNC cables for optimal results. The
absolute maximum input range for these inputs is
±
40 volts.
Do not exceed this
level or damage can result to the input circuitry.
