(c) Ensuring isolation
(d) Precautions related to emulation probe
Emulation probe
When connecting the target system to the QB-179F124 using an emulation probe, adjust the height using the
front space adapter or rear space adapter of the QB-179F124 and ensure isolation from the target system.
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
<2> Be sure to connect the GND wire of the emulation probe to the QB-179F124 and the target system. If
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.
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.
