CHAPTER 2 SETUP PROCEDURE
(c) Ensuring isolation
When connecting the target system to the QB-78K0FX2 using an emulation probe, adjust the height using the
front space adapter or rear space adapter of the QB-78K0FX2 and ensure isolation from the target system.

(d) Precautions related to emulation probe
The following precautions pertain to using the 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-78K0FX2 and the target system. If not,
the impedance of the cable becomes unstable, resulting in the 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.
