Using the Front Panel Display. The front panel touch screen display (icons shown below) can be used for impedance
testing, waveform preview, and on-the-fly device configuration.
Open System Setup screen

information.
Hardware Setup. Use the provided
5-meter paired fiber optic cable to
connect the PZ5 to the RZ processor,
as shown below. The connectors are
color coded and keyed to ensure
proper connections.
Create a new logical amplifier. If all banks are
configured, the green plus sign is not displayed.

Software Configuration. Logical amplifiers
can be configured on the Synapse, PZ5
options page. The table below lists default
settings for each analog input amp type.
Touch the icon in the logical amp configuration
area (shown below) to display the desired screen
for the corresponding logical amplifier.
A red outline indicates a bank is
configured, but no headstage
is detected. Colors inside the
frame indicate the logical amp
type (gray= unconfigured).

To test the impedance of your hardware set-up:
• Touch the icon on the desired logical
amplifier to display the Impedance Checking
screen.
To scroll the visible channels:
• Swipe vertically on the interface.
Settings include:
Target. Impedance values above the target will be red,
values <75% below the target will be green and all other
values will be yellow.
Frequency. Choose the probing frequency.
Probing. Select the pins to measure. Available options
depend on the logical amp referencing mode (listed
below).
Ref, GND, and AltRef values displayed on top row.
Differential: Inp(+) the positive input channels
Inp(-) the differential channels
Local: Input all input channels
Ref the reference impedance to
ground
AltRef the alternative reference (pin
13)
Shared: Input all input channels
Ref the reference channel
Gnd the ground impedance
None: Input the input channels
Sort. Display channels with the largest variation from
the target impedance at the top of the screen.
Auto. Cycle through probing options each second.
Next. Advance to the next probing option set.
To return to the Main Configuration screen:
• Swipe three fingers across the screen in any
direction.
