SECTION 2
PRECAUTION
This section describes the preparatory work which must be performed before using the MG3641A/MG3642A Synthesized
Signal Generator and the precautions relating to (1) installation and (2) power supply. For GPIB cable connection, address
setting, etc, see Section 6.
2.1 Installation Precautions
This paragraph describes the MG3641A/MG3642A Synthesized Signal Generator installation precautions and
mechanical assembly procedure for mounting the MG3641A/MG3642A in a rack.
2.1.1 Installation site environmental conditions
(1) Location to avoid
The MG3641A/MG3642A operates normally at ambient temperatures of 0° to 50°C.
However, for best performance, do not use or store it in locations where:
It may be subjected to strong vibrations
It may be exposed to extreme humidity or dust
It may be exposed to direct sunlight
It may be exposed to explosive gases
To maintain stable measurement for a long time, in addition to meeting the conditions listed above, the MG3641A/
MG3642A should be used at stable room temperatures and where the AC line voltage fluctuations are small.
CAUTION:
If the MG3641A/MG3642A is used at room temperature after being used or stored at a low temperature
for a long time, condensation may occur inside the instrument which could cause short circuiting. Always
ensure that the MG3641A/MG3642A is thoroughly dry before turning on the power.
(2) Fan clearance
To prevent excessive temperature increase inside the MG3641A/MG3642A, a cooling fan is mounted on the rear
panel. Leave a space of at least 10 cm between the rear panel and walls, peripheral devices, obstructions, etc. so
that air flow is not obstructed. Do not use the MG3641A/MG3642A on its side.
10cm
Do not use the MG3641A/
MG3642A in this orientation
