Environmental Requirements
Instrument meets the requirements of Tektronix Standard 062-
2853-00, Class 5, except EMI.
The instrument meets the following MIL-T-28800C requirements
for Type III, Class 5 equipment, except where noted otherwise.
Temperature
Operating
0°C to +50®C (+ 3 2 ‘ F to + 122'F).
Nonoperating
—55®C to +75°C (—67®F to + 167'F).
Tested to MIL-T-28800C, para 4.5.5.1.3 and 4.5.5.1.4, except that
in para 4.5.5.1.3 steps 4 and 5 are performed before step 2
(—55 °C nonoperating test). Equipment shall remain off upon
return to room ambient temperature during step 6. Excessive con­
densation shall be removed before operating during step 7.
Altitude
Operating To 4,500 meters (15,000 feet). Maximum operating temperature
decreases 1 'C per 1,000 feet above 5,000 feet.
Nonoperating
To 15,000 meters (50,000 feet).
Humidity
Operating and Nonoperating 5 cycles (120 hours) referenced to MIL-T-28800C para 4.5.5.1.2.2
for Type III, Class 5 instruments. Operating and nonoperating at
95%, —5% to +0%, relative humidity. Operating, +30® C to
+ 5 0'C ; nonoperating, + 3 0 'C to +60®C.
EMI (electromagnetic interference) Meets radiated and conducted emission requirements per VDE
0871, Class B.
To meet EMI regulations and specifications, use the specified
shielded cable and metal connector housing with the housing
grounded to the cable shield on the AUXILIARY CONNECTOR.
Vibration
Operating 15 minutes along each of three major axes at a total displacement
of 0.015 inch p-p (2.4 g at 55 Hz) with frequency varied from
10 Hz to 55 Hz to 10 Hz in one-minute sweeps. Hold for 10
minutes at 55 Hz in each of the three major axes. All major reso­
nances are above 55 Hz.
Shock
Operating and Nonoperating
30 g, half-sine, 11 ms duration, three shocks per axis each direc­
tion, for a total of 18 shocks.
