Power requirements
The M1650A does not have an AC power connection. It is powered by a DC
voltage from the E7760A Wideband Transceiver, which is supplied over the RF
Cable Assembly. The DC supply does not represent a risk of personal injury.
Using Accessories
Use only the RF Cable Assembly which has been supplied with the M1650A to
connect it with the E7760A, and connect it only to the mmW ports on that
instrument.
VENTILATION REQUIREMENTS: When installing the instrument(s) into a
cabinet, consideration shall be given to the convection flow into and out of the
cabinet. Consideration shall also be given to the individual instruments to avoid
having the heated discharge of one instrument, now becoming the cooling
intake air for another instrument.
Another area of concern is verification that the maximum ambient operating
temperature of the instrument(s) is not exceeded by cabinet installation.
Keysight recommends forced air convection whenever an instrument(s) are
installed in a cabinet and further recommends that the maximum operating
temperature of the cabinet be reduced 10°C from the lowest, of the maximum
operating temperature of a single instrument.
If there are any concerns or special requirements an Keysight Field Engineer
should be consulted to assure instrument(s) temperature compliance and
performance.used.
The RF Cable Assembly should not be connected to, or disconnected from, the
M1650A while it is suppling DC power from the E7760A. This connection
should be made only when the E7760A is powered off, or the cable is not
connected to the E7760A. If the LED status indicator on the front of the
M1650A is lit, this indicates that it is powered up and the cable should not be
disconnected.
