5. Operation and Maintenance
Operation:
All RF connections should be made to the Converter and Receiver before the power supply is connected and
turned on. Power is applied by toggling the power switch on the front panel to the UP position. Power is
removed by toggling the power switch to the DOWN position.
IMPORTANT
: After the Converter has been in operation and if the coaxial cables need to be disconnected, the
power switch should be turned off and the power cable removed before disconnecting the coaxial cables. If the
Converter is used with the LWA Power Coupler (LWAPC), follow the instructions associated with the power
coupler before applying or removing power from either unit.
Maintenance:
The Converter requires very little periodic maintenance. Converter maintenance described below should be
performed when performing regular maintenance on the Callisto instrument, other receiver or power coupler.
A.
Monthly Preventative Maintenance
☼
Brush dust off the instrument being careful to not disturb the connections
☼
If additional cleaning of the enclosure and panels is required, use a damp cloth; DO NOT use any
chemicals (or else the silkscreen may dissolve)
☼
Check condition of all cables and connectors
B.
Annual Preventative Maintenance
☼
Check power supply voltage, 12 Vdc
☼
Check local oscillator frequency, 200 MHz
±
20 kHz (measure at IF Output with a frequency counter)
after > 2 h warmup. The oscillator is not tunable; it is recommended that the unit be returned to the
factory if the LO frequency is out of specification.
C.
Internal RF connectors
If the internal type SMA RF connectors are loose or removed and replaced, torque them to 45 N-cm (4
in-lb).
