● Re-orient or relocate the affected equipment.
● Increase the distance between the instrument and the affected equipment.
● Re-orient or relocate interface cables.
● Connect the instrument to an outlet on a different supply circuit to the affected
equipment.
Electrical supply cables, interface cables and probes should be kept as short as prac-
tical, preferably a maximum of 1 m. Interface cables should be screened and interface
cables longer than 3 m are not acceptable in terms of interference port immunity.
An electrical frequency of approximately 270 kHz or equipment working with an electrical
frequency of approximately 270 kHz can interrupt the stability of the GEN7iB touch screen.
Under these conditions, the touch screen may become erratic or unusable. If such interfer-
ence occurs, please contact your local supplier for more details.
During mains immunity testing, some of the USB ports combined with other parts, such as
keyboards, failed during the disturbance bursts and the drivers needed to restart to resume
the operation. Whenever you experience this malfunction, using a ferrite coil on the USB
cable will resolve the problem (See Fig. 3.1).
