Description
Target
Select the target impedance from a drop down list (1 kOhms -100 kOhms). This is used to color the
impedance value text during/after probing. Impedance values above the target are colored red,
values <75% below the target are green and all other values are yellow.
Freq.
Set the probe signal frequency from a drop down list. The frequency is adjustable from 35 Hz, 70 Hz,
140 Hz, 280 Hz, 560 Hz, 1120 Hz, and 2240 Hz. This feature is only selectable in daughter board
fi
rmware v1.3 and above, and PZ5 software v1.1.1 and above. The frequency is
fi
xed at 140 Hz in
prior versions.
Probing
(Analog input amps only) Select the set of connections to measure. The available options in this list
change depending on the logical amp referencing mode. See table below.
