Tech Note: TN2203
Product: RZ, RZ2, RZ5, RZ5P, RZ5D, RZ6, RZ10
Version: All

Issue

In some RZ units, occasional one sample -10 V transients are seen on the ADC inputs. In RZ10 devices, this is visible on the sensor raw stream and the demodulated signal.

Solution

The fix requires a modification to the RZ motherboard at TDT. If you experience this problem, contact TDT for an RMA.
