(d) Precautions related to emulation probe
<1> Be careful that stress of the emulation probe is not placed on the target connector. Moreover, when
removing the emulation probe, remove it slowly while pressing down on the exchange adapter with a
finger so that there is no stress on the target connector.
<2> Be sure to connect the GND wire of the emulation probe to the QB-78F1030 and the target system. If
it cannot be connected, the impedance of the cable is unstable and could bring about lowering of
signal transmission characteristics or distortion of the output waveform for an input waveform.
2.7 Notes on Power Supply and GND Pin Connection
For power supplies and GND pins of the target device, be sure to connect all pins to each power supply or GND.
