Performance Requirements
Environmmental requirements qualify the electrical and
mechanical specifications. When not rack mounted, the
instrument meets the environmental requirements of
MIL-T-28800C for Type III, Class 3, Style C equipment,
with the humidity and temperature requirements defined
in paragraphs 3.9.2.2, 3.9.2.3, and 3.9.2.4. Rack
mounting changes the temperature, vibration, and shock
capabilities. The rack mounted instruments meet or
exceed the requirements of MIL-T-28800C with respect
to Type III, Class 5, Style C equipment with the rack-
mounting rear-support kit installed. Rack mounted
instruments will be capable of meeting or exceeding the
requirements of Tektronix Standard 062-2853-00,
class 5.
-15°Cto +55°C.
For a rack mounted instrument, ambient temperature
should be measured at the instrument's air inlet. Fan
exhaust temperature should not exceed + 65°C.
-62°C to -r85°C.
To 15,000 feet. Maximum operating temperature
decreases
1
°C for each 1000 feet above 5000 feet.
To 50,000 feet.
Stored at 95% relative humidity for five cycles (120
hours) from 30°C to 60°C, with operational
Vibration (operating)
Not Rack Mounted 15 minutes along each of three axes at a total
displacement of
0.025
inch p-p (4 g at 55 Hz), with
frequency varied from 10 Hz to 55 Hz in one minute
sweeps. Hold 10 minutes at each major resonance or, if
none exists, hold 10 minutes at 55 Hz (75 minutes total
test time).
Rack Mounted Change displacement to 0.015 inch p-p (2.3 g at 55 Hz)
