Onboard Analog I/O and Optional Ampli fi er Input
The RZ6 is equipped with onboard analog I/O and attenuators. It may also include a fi ber optic
port for Medusa preampli fi er input.
The table below provides a quick overview of these I/O features and how they must be
accessed during experiment design.
Onboard Analog Inputs
The RZ6 is equipped with two channels of 24-bit sigma-delta A/D converters. See RZ6
Technical Speci fi cations for more information.
Analog signals can be input through several connectors on the RZ6 front panel.
Channel A has three possible sources:
MIC-A (XLR microphone input)
DIFF-A (¼" TRS microphone input)
BNC labeled In-A
Indicator Description
Cyc Cycle usage. For QZDSPs, the highest core cycle usage is shown
Bus% Percentage of internal device's bus capacity used
I/O% Percentage of data transfer capacity used
DAC Displays the current analog attenuator setting. Also displays bars according to the RMS level of DAC A
and B using a logarithmic scale
Note: Eight solid bars denote that the signal on DAC A or B is clipping.
ADC Displays bars according to the RMS Level on ADC A and B using a logarithmic scale.
Note: Eight solid bars denote that the signal on ADC A or B is clipping.
