Device Housing
The QM2010 housing is a doubled sided pin fin heat sink constructed of anodized aluminum as shown in
Figures 12 and 13. This creates an extremely rugged package that provides adequate surface area for natural
convection cooling and EMI protection for the sensitive electronics housed within. The device should be kept
clean and unobstructed in order to promote air circulation. Because the device is cooled through natural
convection, a case temperature rise of +20
o
C over ambient conditions can be expected. If this product is used
outside of a lab environment (+30
o
C ambient conditions) users are urged to exhibit care while handling the
device, such as wearing heat resistant gloves or applying forced air cooling with an external fan.

– QM2010-10-20 Side View, Status LEDs and External Reference Input
Figure 13 shows the status LED locations on the QM2010 series of USB stick synthesizers. The blue LED to
the left of the “USB” text will illuminate when the device is enumerated by a host PC. The “LOCK” LED will be
green when the device is phase locked or red if the device is unlocked or has RF power disabled
. The “EXT
REF” LED should illuminate yellow when the device is set to lock to an external reference. When locking to the
internal 50 MHz reference, the EXT REF LED should be off.
