Power requirements
The M1740A does not have an AC power connection. It is powered by a DC
voltage from the E7760B Wideband Transceiver or the E7770A Common
Interface Unit; this voltage is supplied over the RF Cable Assembly to the
LO/Pwr/Ctrl/IF In connector. The DC supply does not represent a risk of
personal injury.
Using Accessories
When the M1740A is used in connection with the E7760B Wideband
Transceiver or the E7770A Common Interface Unit, use only the RF Cable
Assembly that was supplied with the M1740A to connect it with the other
instrument, 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
M1740A while it is suppling DC power from the E7760B or E7770A. This
connection should be made only when the E7760B is powered off, or the cable
is not connected to the E7760B or E7770A. If the LED status indicator on the
front of the M1740A is lit, this indicates that it is powered up and the cable
should not be disconnected.
