System 3
Logical Amplifiers
Though each bank has its own ground and reference, a single ground and reference
can also be defined and shared across all banks of the logical amplifier. See
Reference Modes for analog input banks below.
Digital boards can be configured individually or grouped to share a single ground and
use common filter settings and sampling rate.
Note: Channel numbering on digital input banks can be non-sequential when sampling at
50 kHz. See "Sampling Rate and Digital Input Channels" on page 6-7.
Logical amplifier configurations can be defined using the front panel interface (see
"Using the PZ5 Front Panel Display" on page 6-10) or the PZ5_Control macro.
The PZ5-32 model can have a maximum of two logical amplifiers configured. All
other PZ5s can have a maximum of four logical amplifiers.
Reference Modes
The PZ5 supports four referencing modes for each analog input logical amplifier:
Local, Shared, None and Differential. Reference and Ground configurations for each
logical amplifier can be defined using the PZ5_Control macro or via the touchscreen
interface. See "Pinout Diagrams" on page 6-28.
